This is a list of rooms in Sector 3 / Pyrosphere in Metroid: Other M. Larger rooms have their own pages and are previewed here. Many of these names are unofficial; such names will be highlighted in quotation marks.

Long elevator shaftEdit

Main article: Long elevator shaft
Samus enters Pyrosphere corridor HD

The long elevator shaft is a room on the BOTTLE SHIP in Metroid: Other M. It acts as a connecting shaft between Sector 1 / Biosphere and Sector 3 / Pyrosphere. The room is partially playable, and cannot be accessed again after Samus passes through it. The shaft is accessible from the Biosphere Test Area, outside and to the right of the Exam Center. It may even be part of the Exam Center building, as the entry door is seen blending into a projection of an open field environment with bushes and trees. This is because after being wounded by Anthony Higgs, the Mystery Creature threw itself through the door, damaging the holographic projection.

Red corridor

The "red-lit corridor" is a room in Sector 3 / Pyrosphere. It appears in Metroid: Other M. This is a simple, empty room connecting the "long elevator shaft" to the lava cavern. It is the first room in the Pyrosphere to be explored during gameplay, as the elevator shaft is entered automatically and then entirely explored in a cutscene. When Samus enters this room, Adam contacts her with mission orders.

Inclined corridorEdit


The "inclined corridor" connects to the lava cavern from two exits, and into a Navigation Booth to the right. It is a two-level stairwell connecting from the upper area with the broken glass tube, to the lower area that is exposed to hot air. Both sets of stairs have a noticeably red railing. The Navigation Booth benefits Samus, as she will have a checkpoint if she dies during the Vorash chase sequence that will occur when she enters the outdoor lava cavern.

On the floor in between the sets of stairs is a small alcove in the wall with three Pow. They serve as a hint that there is an item in the wall; in this case an Energy Part through a tunnel. The lower staircase has a blast shield on it that can be removed with a Super Missile; doing so allows Samus to go under the stairs and obtain a Missile Tank.

Navigation Booth AEdit


Navigation Booth A is the first Navigation Booth in the Pyrosphere. When Samus uses the booth for the first time, the Map populates and creates a waypoint to the next Navigation Booth outside the heated shafts. Unlike most Navigation Booths, this one only has a single exit.

Pyrosphere combat arenaEdit

Pyrosphere combat arena

The "Pyrosphere combat arena" is a room in Sector 3 / Pyrosphere. It appears in Metroid: Other M. Samus first enters this room while she is escaping the Vorash chasing her in the adjacent vast lava-filled cavern. When she approaches the next door, a Cyborg Zebesian drops in and begins a battle. Gradually, three more appear and after two are killed, a Fly Pod on the left wall will rain meteors down on the room, and begin spawning Mellas. After a few seconds, Adam authorizes Samus to use her Ice Beam.

Ventilated corridorEdit


The ventilated corridor is a horizontal hallway with a sand floor and eight wall vents (in pairs) that release steam and fire at regular intervals. There are several rectangular lights on the ceiling and wall as well. The floor is uneven and there are several raised sections of rock protruding from under the sand, and what appear to be two electricity panels on either end of the hallway.

Flame hallwayEdit

Main article: Flame hallway
Flame hallway

The "flame hallway" is a room in Sector 3 / Pyrosphere. It appears in Metroid: Other M. The room is similar to the preceding corridor with its uneven, sandy floor and the presence of flaming heat vents, except the camera positions the hallway so that it is vertical. Several rock slabs are found poking out of the sand, which can be vaulted over much like other barriers in rooms on the BOTTLE SHIP. The room is lined with several vents and pipes, the former of which exhausts flames at regular intervals, similar to the flame jets in the Magmoor Caverns.

Navigation Booth BEdit


Navigation Booth B is the second Navigation Booth in the Pyrosphere, found outside the heated shafts. When Samus uses the booth for the first time, the map populates with the locations of two other Navigation Booths, but points Samus to only one due south of her position.

Infested L-shaped corridorEdit


The "infested L-shaped corridor" is accessed from the northern side of the lava cavern. It is inhabited by about four Sovas, and there is a Fly Pod around the corner that spawns Mellas until destroyed. It leads into the Floor Observation Room.

Floor Observation RoomEdit

Floor Observation Room Samus

The Floor Observation Room is a room in Sector 3 / Pyrosphere. It appears in Metroid: Other M. The Floor Observation Room is located in an indoor facility. It is likely that the ringleaders observed various experiments in this room. In the center of the back wall is a raised platform with a staircase, and a Terminal with two seats in front of a desk. These are separated from the rest of the wall by a pair of buttresses. On either side of this are a pair of large wall-mounted screens, one of which is displaying static. The other displays unknown schematics.

Inside corridorEdit


The "inside corridor" leads from the Floor Observation Room back out into the superheated environment of the Pyrosphere. There is little to it feature-wise; its notable features are tubular lights mounted on the walls and floors, with the wall lights standing behind gates. Halfway through the corridor on the right side is a tunnel on the wall, which leads to a Missile Tank back in the wall within the Floor Observation Room. On the initial visit the room is empty, but after Samus's return to the Pyrosphere it is inhabited by Sovas and Cyborg Zebesians.

Volcano corridorEdit

Main article: Volcano corridor
Volcano bridge Pyrosphere HD

The "volcano corridor" is a room in Sector 3 / Pyrosphere. It appears in Metroid: Other M. As the name implies, this room features the volcano that was visible in the main "lava cavern", prominently in the background. The room itself is a long bridge built directly over lava, with barricades on either side to prevent passengers from falling in. The bridge is surrounded by stalagmites protruding from the lava, and the room is open to the Pyrosphere's extreme heat once again after several indoor rooms.

Navigation Booth CEdit


Navigation Booth C is the third Navigation Booth in the Pyrosphere. It immediately follows the volcano corridor, in which Samus would have lost a lot of energy from exposure to extreme heat. When Samus uses the booth for the first time, the map populates with the location of the next Navigation Booth, as well as the Main Sector elevator. On her first visit, the room may rock a little from the volcanic meteors impacting the floor outside.

Interior entranceEdit

Main article: Interior entrance
Interior entrance

The "Interior entrance" is a room in Sector 3 / Pyrosphere. It appears in Metroid: Other M. The entrance is a small indoor room in the shape of a half hexagon. In the center of the floor is a glass pane with lava visible beneath it, and a terminal on the back wall. The terminal controls the lava level, and it must be used to drain the lava so that passage inside the Crater Interior is possible. As the lava drains, at least two grates can be seen in the wall, suggesting that the lava was flowing into the shaft from an unknown source.

Launcher hallwayEdit


The "launcher hallway" is a straightforward corridor connecting the lower Crater Interior to the Main Sector elevator. The room contains five Sovas and a one-way Morph Ball launcher in an alcove, which Samus comes through using a shortcut after the Geothermal Power Plant.

Transport to Main SectorEdit

Pyrosphere Main Elevator

"Transport to Main Sector" is the Pyrosphere 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.

Rhedogian room - lower

The "Rhedogian room" is a major room in Sector 3 / Pyrosphere. It appears in Metroid: Other M. Several mini-boss fights take place in this room. The room appears as a long hallway with buttresses and yellow fluorescent lights mounted on the walls. The other end of the room is raised high, and can only be ascended either with a Grapple Point floating above the lower floor, or by using a Kick Climb shaft in a wall alcove below. Next to this ledge on the left wall is an extended platform, which Samus can jump off of.

Dessgeega-infested hallEdit


The Dessgeega-infested hall[1] is a simple, L-shaped corridor. Near both of the doors are two dividers on the floor that Samus will automatically vault over when she approaches. As its name implies, the most notable feature of the room are the two Dessgeegas, which stomp around aimlessly. Samus can choose whether to kill them or not. Upon entering the room initially, she is greeted by five Mellas. Aesthetically, the room has little in the form of unique features, apart from a series of curved orange lights on the walls. This room leads into a Navigation Booth connected to the "lava crossing" (see below).

Navigation Booth DEdit


Navigation Booth D is the fourth Navigation Booth in the Pyrosphere. It follows the Dessgeega-infested hall and leads into the lava crossing. After Samus is unable to cross, she returns here and receives a transmission from Adam. The map directs her to the Main Sector elevator.

OK, Samus. Head to Sector 2. There's a high probability of survivors hiding there. We'll have to take care of that freak of nature later.

—Adam


Lava crossingEdit


The "lava crossing" is a room preceding the mentioned Navigation Booth. As the name implies, it is filled with lava and cannot be crossed without using Grapple Points. Aside from the ledge Samus enters the room on, there is one platform in the middle and then the one at the other end, each higher than the one before. When Samus enters it for the first time, she will find herself unable to cross it because the Grapple Beam has not been authorized. Upon going back into the Booth, she is directed to look for survivors in the Cryosphere. After returning - shortly before which the Grapple Beam was authorized - Samus is able to cross the room, into Blast Furnace Observation. In an alcove under the floor on the other side is an Energy Part. The room is inhabited by a Magdollite on further visits.

Blast Furnace ObservationEdit

Blast Furnace Observation - Vorash

Blast Furnace Observation is a significant room in Sector 3 / Pyrosphere. It appears in Metroid: Other M. The room features two areas: the observation area, and the Blast Furnace itself. Samus comes to this room en route to the Geothermal Power Plant. She navigates through the tunnel network and releases the Grapple Points. The second one falls into the mouth of the Vorash - a creature that tried to eat Samus in the lava cavern earlier - when it leaps from the lava and swallows it. The rest of the Grapple Points float above the lava, and are usable.

Navigation Booth EEdit


Navigation Booth E is the fifth Navigation Booth in the Pyrosphere. It immediately follows the Blast Furnace Observation room. When Samus enters for the first time, Adam contacts her again before she can use the booth. Once he is done speaking to her, the map populates with the Geothermal Power Plant's location, and the door locks until Samus uses the booth.

Samus, it looks like that monster is headed to the geothermal electric-power generator. [Samus gasps]

Track it and put an end to it.

—Adam

Using the booth populates the map with the next set of rooms in the experimental simulated desert area.


Sandfang hallEdit


The "Sandfang hall" follows immediately from a Navigation Booth after the Blast Furnace. It is the first room of the Pyrosphere's experimental simulated desert area. The uneven floor is covered in sand and if walked over, a Sandfang will spawn. It is possible to avoid drawing out the creature by grappling over it using a Grapple Point.

Environmental Test FloorEdit

Environmental Test Floor 1

The Environmental Test Floor is a room in the experimental simulated desert area of Sector 3 / Pyrosphere. It appears in Metroid: Other M. Inhabiting this room are two Dessgeegas and a pair of Sandfang. The room itself is an open space with a sand floor, and multiple dunes surrounded by protruding, jagged rocks and sections of rebar. Toward the back of the Test Floor is a large, holographic cliff wall, with a door to get inside the tower being on a platform higher up, but initially concealed by the hologram. Samus is not required to engage the enemies in the room, but doing so will allow her to navigate without interference.

Mella stairwellEdit


The "Mella stairwell" is a confined, black staircase with yellow lights. There are four Mellas in the room, hence the name. It leads directly into the next named room, the Desert Refinery.

Desert RefineryEdit

Main article: Desert Refinery
Powergrip

The Desert Refinery is a room in the experimental simulated desert area of Sector 3 / Pyrosphere. It appears in Metroid: Other M. The Desert Refinery is a large room where sand in the surrounding desert area is refined. Whether this serves a purpose for the bioweapons projects aboard the BOTTLE SHIP, or is for general maintenance is unknown. Several towers in the room are seen grinding and releasing sand particles.

Curving catwalkEdit


The "curving catwalk" is a midair catwalk suspended over an indoor facility. Samus is attacked by multiple FG-1000 and FG II-Graham units here. Once she has cleared them out, she must Speed Boost along the catwalk and Shinespark up at the end to reach a higher ledge with a wall hole leading into a midair tunnel in the Desert Refinery, which then leads into another Navigation Booth.

Navigation Booth FEdit


Navigation Booth F is the sixth Navigation Booth in the Pyrosphere. It follows the Desert Refinery from the highest floor. There is no update to the map after using this booth.

Multi-step catwalkEdit


The "multi-step catwalk" is entered from the above-mentioned Navigation Booth. It is similar to the curving catwalk; however, there are many more robotic units and the pathway is not free of obstructions. Along the way are several raised steps that must be jumped over, and floor barricades that Samus can vault over. The raised sections have ladders on them, which are unusable by Samus. These were likely used by the ringleaders and/or other BOTTLE SHIP staff, who did not have the agility and movement that Samus does.

Sand Tower summitEdit

Sand Tower summit

The "Sand Tower summit" is a room in the experimental simulated desert area of Sector 3 / Pyrosphere. It appears in Metroid: Other M. This circular room is located at the top of the Desert Refinery and constructed entirely out of metal and steel with a tiled floor. The room is surrounded by barriers that are open to the indoor complex outside, but cannot be passed through by Samus. Behind the barrier are sections of wall, buttresses lined with a bright yellow light or accent, and a screen spanning the width of the room that reflects the yellow lights or accents. Being round, the room has no corners, although the north, south, east and west sides of the floor use sections of black, patterned tile with a grey border.

The "desert cave" is a room in Sector 3 / Pyrosphere. It appears in Metroid: Other M. This room is located in the lowest region of the Desert Refinery, and is reachable by descending the elevator from the refinery's summit. It is a straight hallway that is, unlike the rest of the refinery, uninhabited save for a Dragotix. By this point in the mission, Samus is able to dispatch it with ease.

Lava pondsEdit


The "lava ponds" are accessed from a high ledge in the lava cavern, which is reached by ascending three platforms near the door to the infested L-shaped corridor and using a series of Grapple Points. The room is a short hallway inside a cave with several fissures of exposed lava. It is not difficult for Samus to navigate around the pools, although there are several Magdollites which can make movement difficult unless they are destroyed. It leads into a Navigation Booth.

Navigation Booth GEdit


Navigation Booth G is the seventh and final Navigation Booth in the Pyrosphere. It follows the lava ponds and leads into the carcass room. Using the booth populates the map with the rooms leading up to and including the Geothermal Power Plant.

Carcass roomEdit


The "carcass room" is entered right after the Navigation Booth. Samus automatically enters Search View upon stepping into here, noticing a molted husk on the wall - that of the Mystery Creature she had been tracking. The husk was not removed by the Galactic Federation upon their seizure of the BOTTLE SHIP and remains there after the credits. The room is illuminated through the presence of lava underneath the floor, seen through impenetrable glass. A Missile Tank can be found in this room. If the next corridor is cleared of enemies, and Samus Speed Boosts back into this room, she can Shinespark to the ceiling and Space Jump to a ledge on the right with this tank.

Glass tubeEdit


The "glass tube" is, as the name would suggest, a long glass tube situated above lava. The tube itself is similar to that found in the lava cavern, but remains intact for the duration of the game. When Samus enters the room for the first time, more unsettling music begins to play. Along the path are three pairs of two FG-1000 units, extending an electrical field in Samus's path. Contact with the path deals 35 units of damage to Samus. She can either jump over the fields or shoot the drones to remove them. Either way, she can then proceed into the Geothermal Power Plant.

Geothermal Power PlantEdit

Geotherrmal Power Plant Grapple Beam Point Pyrosphere HD

The Geothermal Power Plant, also referred to by Adam Malkovich as the geothermal electric-power generator, is a room in Sector 3 / Pyrosphere. It appears in Metroid: Other M. In a previous room, Anthony Higgs mentioned to Samus that he and the rest of the 07th Platoon were sent to the Geothermal Power Plant to open the magma-eruption port, in order to restore power to the Pyrosphere. After she leaves, she proceeds after him.

UndershaftEdit


The "undershaft" is the final room of the Pyrosphere and is reached through a Super Missile blast shield in the outer Geothermal Power Plant. It begins as a hallway that turns into a drop shaft with Grab Ledges on either wall. The bottom of the first shaft contains lava. A hole in the left wall further down leads into a tunnel with a Missile Tank. Similar to the earlier heated shafts, a sensor (this time farther down) must be shot to open a blast door that leads to a Morph Ball launcher, which takes Samus back to the launcher hallway.
