List of rooms in Metroid: Other M

This is a list of rooms in Sector 1 / Biosphere in Metroid: Other M. Larger rooms have their own pages and are linked here. Many of these names are unofficial; such names will be highlighted in quotation marks.

Transport to Main Sector[]

Biosphere Main Elevator

"Transport to Main Sector" is the Biosphere variant of a room in every sector that contains an elevator connecting to the Main Elevator in the Main Sector. The elevator in each room is connected by a downward ramp to a convex path, with a railing around the exterior in the foreground. The only major difference in each room is the color of the wall-mounted computer terminals, elevator and ambient lights - green, blue or red depending on the Sector.

Navigation Booth A[]


Navigation Booth A is the first Navigation Booth in the Biosphere. When Samus uses the booth for the first time, the Map populates and creates a waypoint to the next Navigation Booth outside the grand tree room. The door to the next room is locked on the first visit; after Samus uses the booth and her map is updated, the camera pans to the unlocking door.

L-shaped corridor[]


The "L-shaped corridor" leads from the Navigation Booth into the overgrown hallway. It has nothing of importance.

Overgrown hallway[]


The "overgrown hallway" is an industrial corridor that has been overtaken by vegetation in the area, namely vines, moss and soil. To the sides of the room are trees with various colors and solar lights on the ground. Samus will automatically vault over the vines. There are two Fly Pods in the room, spawning Reos, and two Grippers, which are both situated in front of a Fly Pod. At the end of the room is a pair of steps that Samus must jump up to reach the exit, which is blocked by a wall of vines. She can destroy it with a Missile. There is another small corridor through here before the next room.


Confrontation room[]

Main article: Confrontation room
Confrontation room

The "confrontation room" is one of the first rooms in Sector 1 / Biosphere. It appears in Metroid: Other M. This room is the setting for at least three enemy confrontations during Other M. When Samus first enters the room, the door will lock, and part of the ceiling will break, exposing a Grapple Point. This remains unusable even after the Grapple Beam is authorized, until much later in the game. Samus hears a Ghalmanian screech, and one of the creatures appears and grabs her with its tail before slamming her onto the ground. Upon defeating them, the door unlocks and she can proceed.

Fly Pod hallway[]


The "Fly Pod hallway" is a short corridor following the confrontation room. There are two vines on the ground that Samus can vault over, and there is one Fly Pod that spawns endless Reos until it is destroyed.

Grand tree room[]

Main article: Grand tree room
Biosphere central chamber ascension HD

The "grand tree room" is one of the first rooms in Sector 1 / Biosphere. It appears in Metroid: Other M. The grand tree room is one of the largest rooms in the Biosphere. Its name comes from the giant tree in its center, around which is a spiraling walkway leading to a higher area. The room initially opens with a bridge, over which two large vines have extended; these can be vaulted or jumped over. The tree is surrounded by a platform with an impenetrable gate dividing half of it off. From this platform there is a bridge to another door that acts as a later shortcut between this room and the Biological Experiment Floor. This platform is also where the upward walkway is accessed.

Navigation Booth B[]


Navigation Booth B is the second Navigation Booth in the Biosphere, and it is accessed from the top of the grand tree room. This gives Samus a chance to replenish any energy lost during the fight in the "confrontation room" or any enemies who have hit her along the way. When Samus uses the booth for the first time, the map updates with a waypoint to the next Navigation Booth.

Crooked corridor[]


The crooked corridor[1] is a simple zig-zagging corridor with seven Wavers, which are asleep when Samus first enters the room. They will also be asleep on any subsequent visits to the corridor. Once she reaches the first corner, they all awaken and attack Samus. She is not required to kill them all to advance. Samus enters the room from a Navigation Booth connected to the grand tree room and it exits into the rainforest.

Rainforest[]

Main article: Rainforest
Rainforest - lower floor

The "rainforest" is a lush jungle room in the Biosphere. It appears in Metroid: Other M. This room is notable in that this is where Samus encounters Little Birdie for the first time. When Samus enters the room for the first time, a loud screech is heard, and a Griptian appears. The doors are locked until it is defeated. After its death, two Griptians emerge, but the exit door remains locked.

Double-sided corridor[]


The "double-sided corridor" connects directly to the rainforest from the right side, and leads to the Breeding Room. It is the first corridor of an indoor facility, and has an observation window. The camera pans to a two-dimensional perspective when Samus enters the room. There is a fissure in the window, which Samus can roll through with her Morph Ball to get behind the wall. There are two Wavers and two Grippers here, as well as plants, including rafflesia-like plants resembling flowers in the background of green Brinstar. Back in the foreground, a tunnel in the ceiling contains a Missile Tank, and leads into the next room. A hatch on the right side of the foreground can be destroyed with a Super Missile later in the game to create a quicker shortcut between this corridor and the next room.

Stairwell[]

Note: For the G.F.S. Valhalla room, see Stairwell.


The "stairwell" is first entered from the ceiling, via a tunnel from the previous room. It connects back to that room with a door that is blocked by a sturdy hatch, which can only be removed with Super Missiles (authorized later in the game). Part of the floor in front of this door is illuminated with green light. The room itself is unremarkable, with its only notable feature being a wall-mounted schematic on the bottom floor. A door on the top floor leads to the stasis tank room, while the bottom door leads to a corridor connected to the Breeding Room. This door features a unique green design that is rarer on the BOTTLE SHIP. After the sturdy hatch is removed, Samus can run through the previous room and build up speed, then Shinespark in the stairwell up a long shaft to reach a hidden ledge with a small crate containing another Missile Tank.


Multi-door hallway[]


The "multi-door hallway" is a short corridor between the stairwell and the Breeding Room. There are three doors on the left wall, two of which are inaccessible on the first visit. The door at the very end leads directly into the Breeding Room. After the credits, the first door will unlock and Samus can ascend a shaft via Wall Jumping to reach a hidden area with an ornate tree and yet another Missile Tank.

When Dr. Madeline Bergman is explaining MB's revolt to Samus later in the game, a flashback depicts a researcher and two BOTTLE SHIP Security Guards passing through this room to detain MB, who is observing the murder scene in the Breeding Room. MB overpowers and kills the guards and researcher in this hallway as she goes rogue.


Breeding Room[]

Main article: Breeding Room
Breeding Room - curved tree

The Breeding Room is a room in Sector 1 / Biosphere. It appears in Metroid: Other M. The Breeding Room was used for the study of Little Birdie, a small creature kept by the ringleaders as a pet, since its small size made it unsuitable as a bioweapon for the special-forces unit.

Multi-door hallway

Monitoring room[]


The "monitoring room" is a semioval shaped room with numerous observation screens and terminals. Some of the screens show rooms elsewhere in the BOTTLE SHIP, such as the aforementioned ornate tree in the "multi-door hallway" (even before that part of the room becomes accessible). There is a single Geemer in a central stasis tank, filled with an unknown liquid. To leave the area, Samus must destroy the tank with a Missile, killing the Geemer and causing the liquid to spill onto the floor, although it evaporates quickly. Under the Geemer is a hidden Morph Ball tunnel network that leads back into the "double-sided corridor".


Long pathway[]

Main article: Long pathway
Rainforest - lower floor

The "long pathway" is a corridor in the Biosphere. It appears in Metroid: Other M. The hallway is lush with jungle foliage including trees, ferns and stretched roots, which Samus jumps or vaults over. Further along in the room is a pair of Fly Pods attached to the walls that will continuously spawn Reos until they are destroyed.

Items

Missile Tank

Connecting rooms

Rainforest (automatic door)
Pressurized corridor

Pressurized corridor[]


The "pressurized corridor" is another industrial hallway with auxiliary lighting, and gaps in the wall. There are fifteen Geemers in the room, some of which enter via the mentioned gaps. A sensor above the exit door must be used to depressurize the room and allow Samus to proceed. Notably, if any Geemers are alive when the room depressurizes, they will fall to the floor with their legs curled up.

The premise of this room is similar to the Air Lock, the third explored room in Metroid Prime.

Observation Room[]

Main article: Observation Room
Reos MOM

The Observation Room, also called Experiment Floor 1, is a room in the Biosphere. It appears in Metroid: Other M. The Observation Room is open to the sky, and consists of a barren ground with a waterfall that hides a cave. In the sky, there is a window that is seemingly floating there. Behind the waterfall there is a Fly Pod spawning Reos that must be destroyed to expose a hole leading to a tunnel, which must be traversed in Morph Ball form, and leads to a blockage that can be destroyed with a Bomb. This takes Samus up to a cliff high above the room, with a holographically generated background.

Geemer-infested corridor[]


The Geemer-infested corridor[2] is a corridor accessed from the Observation Room, from the top level and after ascending a shaft with the Kick Climb. It is a hallway with blue wall lights and six Geemers, four of which are crawling along the ceiling. There is a small chamber on the left as well, with the other two Geemers in it. There are two grates over this chamber, with the third having been knocked off - presumably by the Geemers - and left on the floor.

Biosphere Missile Tank 3

The Missile Tank.

Samus is not required to kill any of the Geemers to advance, although doing so allows her to collect a Missile Tank. There is a sensor mounted above the door to the Observation Room and shooting it releases gas into the room that kills off the Geemers in the small chamber, allowing Samus to obtain the Missile Tank. She can simply kill the Geemers with her weapons fire, as well.

Waver-infested corridor[]


The Waver-infested corridor[2] is entered from the previous corridor. It is teeming with twelve Wavers and curves around to the right. This leads to a downward slope that has suffered damage, and is lined with two thorned roots. Unless Samus runs up the slope with her Speed Booster (which is not authorized on her first passage), she is unable to return the way she came once she goes down the slope.

The Waver corridor is also referred to as a "long hallway", "hall" and "long hall" (not to be confused with the room in the Main Sector) on page 58 of the Prima Games guide.


Navigation Booth C[]


Navigation Booth C is the third Navigation Booth in the Biosphere, and it is accessed from the Waver-infested corridor. The camera positions the room at a diagonal angle. It is found in a state of auxiliary power, with the exit door being locked even after Samus uses the booth, which creates a waypoint to the next booth. On the left wall is a damaged piece of wall that can be broken open with a Missile or Bomb. It leads to the observation deck. A terminal found in the Subterranean Control Room unlocks the door here.

Observation deck[]

Main article: Observation deck
Observation deck

The observation deck is a corridor in Sector 1 / Biosphere. It appears in Metroid: Other M and is the only room with re-spawning Groganches. Samus enters this room from a Navigation Booth that is running on auxiliary power, via a damaged wall she can rupture using a Missile or Bomb. The room begins with a steep staircase, which is lined with blue safety lights that flicker in parts. This corridor curves around to an observation area with impenetrable glass windows, through which a forest environment can be seen, with palm and other trees.

Navigation Booth C (automatic door)
Lobby (automatic door)

Lobby[]


The "lobby" is an almost rectangular and empty room. There are broken coffee tables to the right of the room with the glass scattered around the tile-patterned floor, as well as a blinking light on the wall. A restroom is accessed by going through the door on the left.

Restroom[]


The restroom[3] is identical to a similar room in the Main Sector and is accessed through the "lobby". It features an inaccessible men's room, and an accessible ladies' room. Samus can open one of the stall doors in the ladies' room to find an Accel Charge, which up to that point would be the first of this kind of power-up that she acquires.

In terms of appearance, this restroom is rather plain-looking, although the red color of floor and stall doors stands out. The other two doors appear to be locked, although no one is using them. A small red light or knob can be seen on the locks to indicate that the stall is "occupied". The game automatically places the camera over Samus's shoulder when she explores this restroom, and she stands with her Arm Cannon raised.


Bull corridor[]

The "Bull corridor" immediately follows the lobby, and as the name implies, contains five Bulls. The close quarters nature of the room means that Samus can easily be affected by the explosion of one or more of the Bulls and take damage, so carefully dispatching them is advisable.

Ghalmanian shaft[]

Main article: Ghalmanian shaft
Ghalmanian shaft - interior shaft

The "Ghalmanian shaft" is an elevator shaft in Sector 1 / Biosphere. It appears in Metroid: Other M. Outside the elevator shaft itself is a path that curves to the right, with a railing mounted to the wall and green lights lining the path to the elevator. There is a terminal to the right of the elevator, presumably to call it, although it cannot be used and does not need to be used for Samus's purposes. There are five Geemers in the lower half of the room, and light can be seen emanating from the ceiling. When Samus enters the room for the first time, a Ghalmanian's purring is heard.

Illuminated corridor[]


The "illuminated corridor" is lined with fluorescent green lights on each wall. To the left of the hallway is a sturdy Blast Shield that can only be removed with a Super Missile, which is not authorized on the first visit. A Missile Tank is found behind the Blast Shield. There is also a hole on the adjacent wall, leading into a tunnel with a small crate containing a second Missile Tank.

Scrap Block[]

Main article: Scrap Block
Waver

The Scrap Block is a room in Sector 1 / Biosphere. It appears in Metroid: Other M. As the name implies, it is used as a garbage dump, and contains lumps of a rubbish resembling webs. They can be cleared away with Missiles or Bombs, and remain destroyed for the rest of the game. In the foreground is a raised platform with a ridged texture and a ramp on the left side, and in the background is a staircase leading up to the exit door. Samus enters the room from a network of tunnels leading in from the Observation Room, and proceeds from here further into the area, eventually reaching the Subterranean Control Room.

Long dirt tunnel

The long dirt tunnel is a room in Sector 1 / Biosphere. It appears in Metroid: Other M. The beginning part of the corridor is blocked by a wall of vines. Samus can remove these with her Missiles, and they will melt when she does so. This reveals a wall, at the base of which is a hole the Morph Ball can fit through. This opens up into a longer corridor with pits in the floor; a Gripper will spawn in one of these. The first time Samus comes through here, the room will rumble, as a Namihe emerges from a wall ahead. It leaps at Samus and a quick-time event occurs where she must SenseMove over it to avoid damage.

Subterranean Control Room[]

Subterranean Control Room - post-Fune and Namihe

The Subterranean Control Room is a group of rooms in Sector 1 / Biosphere. It appears in Metroid: Other M. When Samus first enters the room, she is forced to fight two Ghalmanians. Once they are defeated, she can proceed into the next rooms. Upon her return, she is attacked by a Fune and Namihe, who burst through the walls and ceiling to attack her. Several of the pipes are left bent after the walls are damaged. After the creatures are defeated, a Morph Ball launcher activates in the tunnel Samus entered the room from.

Biosphere Environment Generator HD

The jungle environment is a large room in Sector 1 / Biosphere. It appears in Metroid: Other M. This room is one of many in the Biosphere to contain holographic ecosystems, which can be turned on and off by interfacing with a generator. When the generator is off, the room is shown to be primarily industrial in nature and indoors, with manmade walls and structures, but a floor with grass, trees and ferns. Towards the end of the room on the left is a large pipe, with what are later revealed to be Kihunter webs growing on it. These webs are also present on the ceiling. Green fluid, possibly blood from Little Birdie, can be seen splattered on the left wall as well.

The underground cavern is a room in Sector 1 / Biosphere. It appears in Metroid: Other M. This is a rather unremarkable corridor carved out of a dirt tunnel, although small green or blue ferns can be seen growing from the soil in the walls and floor. At different points of the cavern are stretched roots for Samus to jump or vault over, similar to other natural and manmade barriers in corridors across the BOTTLE SHIP. Unlike other areas of the BOTTLE SHIP, such as the adjacent jungle environment, this room does not appear to be simulated.

Biological Experiment Floor[]

Biological Experiment floor Central Chamber

The Biological Experiment Floor is a room in the Biosphere in Metroid: Other M. The room is the location of a large Kihunter Nest, protected by a King Kihunter. It bears resemblance to the earlier explored "grand tree room" in the area, with a long, curving platform leading to the top of a pillar. However, the room's structures are blue and organic in composition. Several Whipvines are attached to the wall of the central structure and try to hit Samus Aran with their tentacles. A Missile Tank can be found as Samus ascends the hive, on a lower ledge. At the apex of the pillar is a small cave, through which a steep drop follows. A large pink, hollow plant with a gap in its center gives way to the pillar's interior, a round chamber in which the Kihunter Nest is found. Bioluminescent plants decorate the walls here, and the soil floor in the center has a slope, causing Samus to slide down it.

Biosphere intersection[]

H-shaped corridor (first half)

The "Biosphere intersection" is a room in Sector 1 / Biosphere. It appears in Metroid: Other M. The room immediately follows the Biological Experiment Floor. At the end of the cutscene in the Floor where Samus is observing Little Birdie, she runs into this room. The Map automatically updates with the location of the Biosphere Test Area when Samus enters the intersection, and the door locks behind her. On later visits, the room serves as a shortcut back to the "grand tree room" in the first half of the area.

Navigation Booth E[]


Navigation Booth E is the fifth Navigation Booth in the Biosphere, and it is accessed from the Biosphere intersection. Later, Samus sees the Deleter running into the Navigation Booth, but he is gone by the time she gets there.

Jungle hallway[]


The "jungle hallway" is a lush and very overgrown room connecting between the grand tree room and the Biological Experiment Floor, which is otherwise a one-way trip. The vegetation includes inactive Gripper-like venus flytraps, vines and branches. The room is divided by a cliff, which can be ascended using a Grapple Point on each side. A hidden tunnel in the cliff can be entered with the Morph Ball to find a small crate with a Missile Tank. When atop the cliff, Samus can Space Jump to an alcove above the door to the H-shaped corridor, to reach another small crate with an Energy Part.


Crumbling hallway[]


The "crumbling hallway" connects between the grand tree room and the jungle hallway. Apart from vines growing out of the left wall and two segments of damaged floor, the room has little of importance. There are enemies here if it is visited before the Ridley battle, after he is defeated, the room becomes empty.

Box corridor[]


The "box corridor" connects from the Navigation Booth. It is part of an indoor facility but has suffered damage and overgrowth with multiple webs on the walls. The corridor is shaped like an upside down L. The first part, before the corner, contains an elongated vine that stretches across the floor, which Samus can vault or jump over. The other half has suffered more damage with two large boxes in the way. Samus can jump over the first, and jump or roll under the second, which is protruding from the wall. It connects from the H-shaped corridor to the access bridge and the water-filled tank.

Bioweapon Research Center access bridge[]

Biosphere Bridge HD

The "Bioweapon Research Center access bridge" is a room in Sector 1 / Biosphere. It appears in Metroid: Other M. This room leads from the Biosphere into a small room with the only elevator to the Bioweapon Research Center. There is a central bridge in this room that is retractable using a terminal stationed on either side of the room. Each ledge where the bridge connects contains a trio of pillar-like structures with blue light emanating from them. There are also blue lights on the ceiling.

"Transport to Bioweapon Research Center" is the elevator leading to the Bioweapon Research Center from the Biosphere. There is nothing especially unique about this room.

Water-filled tank[]

Main article: Water-filled tank
Water-filled tank Search View (surface)

The water-filled tank is a long room in Sector 1 / Biosphere. It appears in Metroid: Other M. The room is primarily filled with water, hence the name. Navigation of the water is made more dangerous on the first visit due to the Gravity Feature not being authorized. Whether this room has always been flooded is unknown, though the damage to it, and presence of human architecture in the submerged area imply that it was not.

The water-filled room is a room in Sector 1 / Biosphere. It appears in Metroid: Other M. This is an open room filled with water, hence the name. It begins on a high ledge, with a metal staircase to get down. A second set of these is found further in the room. The stairs are each lined with iridescent and rectangular blue lights. Samus, given her ability to survive long falls, can simply jump over the stairs onto a rock platform below. These platforms, and the ledge she jumps from, are covered in grass, ferns and large leaves. Underneath, they are lined with metal gratings.

Biosphere Swamp HD

The Swamp Zone, also called Experiment Floor 2 is a room in the Biosphere. It appears in Metroid: Other M. Upon entrance, the room initially is a marsh-like area with constant rainfall. Throughout the room are trees featuring cylinder-shaped gratings with no bottom, and platforms with Grab Ledges that Samus must traverse to move on through the room. Although there are many of these and much of them are unreachable, placed to confuse Samus, the platforms she must first use are located towards the back of the room.

Navigation Booth F[]


Navigation Booth F is the sixth Navigation Booth in the Biosphere, and it is accessed from the Swamp Zone. On the first visit, the map directs Samus to the Exam Center's entrance, but it is not populated with the rooms leading to the Exam Center until the next Booth.

Stacked crate corridor[]


The "stacked crate corridor" is entered from a Navigation Booth connected to the Swamp Zone. It is initially another L-shaped corridor, but the floor ends around the corner with a drop to a lower area. Large crates are stacked on the floor, forming a "staircase" that can allow Samus to climb back up. There are four Zeros in the room which can molt into Kihunters if not killed in time; two cocoons are found at the entrance upon the first visit and will spawn Kihunters regardless. Across from the edge of the higher part of the room is a hidden platform with a Missile Tank. This can be reached using the Space Jump/Screw Attack once Samus self-authorizes use of them.

Warehouse lift[]


The "warehouse lift" is an elevator room immediately following the stacked crate corridor. On the lower floor are large boxes and shipping crates. The elevator itself is stuck at the top floor. There is an initially inactive Morph Ball launcher on the floor and a series of Grab Ledges on adjacent walls, which is how Samus climbs up on her first visit. The setup of this shaft is similar to the Ghalmanian shaft. When Samus reaches the highest ledge on the left wall, she can fire at a sensor on the opposite wall in Search View to activate the launcher below. Using it sends Samus through the elevator to the better lit top floor, which has more boxes and crates. It leads into the Kihunter corridor.


Kihunter corridor[]


The "Kihunter corridor" is a straightforward corridor with webs on the walls. There are six Kihunters in the room, two of which molt from cocoons. It leads into the Swamp Zone's observation area.

Plant-filled corridor[]


The "plant-filled corridor" is visually similar to the double-sided corridor, but the hallway behind the glass in the background is more difficult to access. Behind the glass near the end of the hallway is a sensor. Samus will need the Wave Beam (authorized later in the game) to be able to shoot it through the wall. When activated, a part of the glass will open for Samus to enter and gain a Missile Tank. This corridor leads directly into the next room.

Experiment Floor Access[]


"Experiment Floor Access" is a corridor formed in an arc. While primarily manmade in construction, it appears to have experienced slight overgrowth of the nearby habitats. Long purple leaves and tree branches, moss and venus flytrap-like plants grow on the walls here. The branches appear to form an arch. There are two Whipvines that guard the room, which are each stationed above mysterious fissures in the floor. It leads directly into Experiment Floor 3.

Metroid: Other M Premiere Edition refers to this room as a "small arching passageway" on page 70.[4]

Experiment Floor 3[]

Main article: Experiment Floor 3
Biosphere forest HD

Experiment Floor 3 is a room in Sector 1 / Biosphere. It appears in Metroid: Other M. The room is quite large and predominately environmental, although it features a Sliding platform, metal track off to the left and network of Morph Ball tunnels. There are several trees in this room of varying species, though it is unknown if these are illusions as with some other elements of the Biosphere and Pyrosphere. The trees create a divide in the middle of the room, forcing Samus to go around if she wishes to explore the other end.

The following rooms are part of the Exam Center and cannot be revisited, as the Center explodes shortly after Samus leaves it.

Exam Center lobby[]


The "Exam Center lobby" is the first room of the Exam Center. There is a path leading directly toward an elevator, which is bordered by three pairs of large columns to each side. The door locks when Samus enters, preventing her from returning to the Biosphere. Once she enters the elevator, it takes her up to another L-shaped corridor.

Desolate L-shaped corridor[]


The "desolate L-shaped corridor" contains a noticeable fog surrounding the floor. There are two deactivated FG-1000 units on the floor. It leads directly into a Navigation Booth.

Navigation Booth H[]


Navigation Booth H is the eighth Navigation Booth in the Biosphere, and the first of two in the Exam Center.

T-shaped corridor[]


The T-shaped corridor[5][6] has numerous thin, rectangular lights mounted on the ceilings, walls and floor, with different colors. The floor lights are dark blue, the ceiling lights are cyan, and the wall lights are white. At least two sections of wall lights are broken, and emitting sparks. To the left of the corridor is a dead-end, with two doors lined with a border that has a black and yellow striped pattern, akin to barricade tape. These doors cannot be opened by Samus and presumably lead to unexplored sections of the Exam Center. A disabled FG-1000 bot is found on the floor here.

Another door to proceed further into the Exam Center is on the right side of the corridor, but locked. The wall beside this door, also lined with the black and yellow borders, has a weak section at its base. Samus can rip a hole in this with a Missile or Bomb to reveal a hidden tunnel keading into a hallway with another disabled FG-1000 bot. This tunnel leads to a security room.


Security room[]


Not to be confused with the Security Rooms in Metroid Fusion.

The "security room" is connected directly to the T-shaped corridor. In here is a terminal that, when used, unlocks the door in the previous corridor, with said door being visible on a screen above the terminal. On either side of the terminal are two pairs of what are likely computer banks. Below the screen are three additional screens: one on the left with a purple monitor, a group of four blue screens in the center, and a light green screen to the right with three horizontal lines.

Terminal hallway[]


The "terminal hallway" is accessed through the previously locked door in the T-shaped corridor. The explorable part of the room is a zigzagging walkway suspended above a lower floor with desks and terminals. Visible from the top are three large screens depicting areas (possibly live feed footage of them) elsewhere in the BOTTLE SHIP, such as what may be the volcano corridor in the Pyrosphere. It leads into a stairwell corridor. Two deactivated FG-1000 units are found here.

Stairwell corridor[]


The "stairwell corridor" has a slight T-shape, and consists of a horizontal corridor lined with a railing, splitting off toward a staircase. Two deactivated FG-1000 units are found before the stairs. When Samus climbs the stairs, the camera suddenly zooms in on the door to the next room, and Samus lets out an audible gasp. The game then shifts to an over-the-left-shoulder perspective where Samus walks slowly, with her hand on her lowered Arm Cannon until she walks into the following room; the main observation deck.

Main observation deck[]

Main article: Main observation deck
Main observation deck

The main observation deck, also referred to as the observation deck is a major room in the Exam Center. It appears in Metroid: Other M. This room is the setting of a cutscene, and is partially playable. Samus first comes to this room when she is exploring the Exam Center. Right outside the room, she gasps as she sees that the door is opened. As she cautiously enters the room, she sees James placing something underneath a console. After he awkwardly greets her, the rest of the 07th Platoon, except for Lyle appears, with the team assuming he is late.

Navigation Booth I (automatic door)

Navigation Booth I[]


Navigation Booth I is the ninth and final Navigation Booth in the Biosphere, and the second of two in the Exam Center. It is first used after Samus regroups with the 07th Platoon in the main observation deck, and can be used again before Samus leaves the center to aid the soldiers. The game places Samus in an over-the-shoulder perspective when she moves through this Navigation Booth, with Samus patrolling slowly and her Arm Cannon lowered. On her return trip, she has the cannon raised.

Locker room[]


The "locker room" connects via Navigation Booth back to the main observation deck. It is a small room with two sets of inaccessible lockers on either wall and nothing else of importance.

Flickering lights corridor[]


The "flickering lights corridor" is a small room with two doors. The first, to the conference room is locked until after Maurice Favreau recovers data from the computer in the main observation deck, while the second leads on. The room has an alcove to the side in the center, and its prominent feature is the mentioned flickering ceiling lights, which turn on and off in a pattern. Part of the right wall can be seen sparking as well.

Cafeteria[]


The "cafeteria" contains two benches, a round conference table, loudspeakers and a pair of vending machines, one of which is damaged. It is likely that the ringleaders used this room when taking a break from their projects.

Dark corridor[]


The "dark corridor" is a short hallway with dim, broken lighting and a sparking ceiling. It has nothing else of importance and simply leads into the next room.

Containment room[]


The "containment room" appears to have been used by the ringleaders for study, as it contains tables and stasis tanks. Some of the tanks have been broken, while others remain intact albeit empty, and have a greenish liquid in them. When approached, some of the tanks' liquid may even bubble up. K.G. Misawa and James Pierce are found here examining a table. They can be examined, but not spoken to.

Cracked corridor A[]


"Cracked corridor A" immediately follows the containment room, and its sole notable feature is a large crack in the left wall. It has nothing else of importance and leads into a decontamination room.

Decontamination room A[]


"Decontamination room A" is a small square-shaped room following the previous corridor. A loud hiss is heard when Samus enters; however, unlike most decontamination rooms the door is not locked. Samus can continue forward through the door and the hissing will stop.

Testing chambers[]

Main article: Testing chambers
Exam Centre room
Multi-door room B

The testing chambers are two identical rooms in the Exam Center, in Sector 1 / Biosphere. They appear in Metroid: Other M. When Samus enters the first chamber, a beeping sound is heard and the door she entered from locks. Through the "top" hatch, Samus is surprised by the source of the beeping, a Cyborg Zebesian that falls towards her. She SenseMoves out of the way and readies her fire, prompting an Examine sequence. Studying the Zebesian's chest reveals that it has a Federation mark, indicating that it has been cybernetically enhanced.The second chamber cannot be accessed until after Maurice has finished recovering data from the observation deck's main terminal.

Decontamination room A (first chamber, automatic door)
Decontamination room B (second chamber, automatic door)

Conference room[]


The "conference room" is accessible from the flickering lights corridor after Maurice recovers data from the Exam Center's main computer. It is an outstretched corridor with two long tables lining it, and multiple chairs. Papers can be seen near the exit scattered about the floor. Anthony Higgs and K.G. are found here investigating, and again can be Examined, but not spoken with.

Cracked corridor B[]

"Cracked corridor B" immediately follows the conference room, and like the previous cracked corridor its sole notable feature is a large crack, this time in the right wall. It leads into another decontamination room.

Decontamination room B[]


"Decontamination room B" is identical in purpose and appearance to the previous such room. It leads into the second testing chamber.
