This is a list of rooms in Sector 2 / Cryosphere 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 SectorEdit

Cryosphere Main Elevator

"Transport to Main Sector" is the Cryosphere 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.

Transport accessEdit


"Transport access" is a short hallway between the Main Sector elevator and the "snow hub". The floor and walls are partially frozen over, and there are two small ice humps on the floor, which Samus can vault over. On later visits, this room is inhabited by a single Baristute.

Navigation Booth AEdit


"Navigation Booth A" is the first Navigation Booth in the Cryosphere. When entered for the first time, the exit door is locked until Samus uses the booth. Her map automatically populates, and directs her to the next Navigation Booth. After this, the Booth in this room is freely usable.

Snow hubEdit

Main article: Snow hub
Snow hub - platforms

The "snow hub" is a room in Sector 2 / Cryosphere. It appears in Metroid: Other M. The snow hub is the first major room of the Cryosphere, and it connects to multiple other rooms. It is a corridor in the shape of an L. It is lined with ice pillar formations and stalagmites, some of which fall over or have already fallen over on the first visit.

The "Fumbleye room" is a room in Sector 2 / Cryosphere. It appears in Metroid: Other M. This room is set indoors, outside of two long corridors that are filled with snow. There is a partial walkway suspended above a pool of water, with a significant chunk of it missing. It is located underwater, in pieces that are connected to a set of pulleys that raise or lower the platforms. The beginning half of the walkway extends under the water, and is lined with a "ladder" of Grab Ledges that can be used to get back up to the surface. All segments of the walkway are lined with blue fluorescent lights.

Snomer-filled corridorEdit


The "Snomer-filled corridor" is a long, winding corridor with steps in an outdoor setting. The floor is covered in snow and the room is surrounded by icicles and ice stalagmites. As Samus runs through the room, Snomers pop out of the floor. She can kill them or ignore them. Near the exit are three Joulions, and two large ice mounds that can be destroyed with Missiles or (later) the Speed Booster. To Shinespark across the chasm in the next room, Samus must build up speed by running through this room.

Ice bridge cavernEdit

Main article: Ice bridge cavern
Ice bridge cavern - running on bridge

The "ice bridge cavern" is a room in Sector 2 / Cryosphere. It appears in Metroid: Other M. This room is an icy cavern in a large cave. There is a long bridge that connects between cliff ledges on both sides of the room. The bridge appears to be naturally formed. Both cliff ledges are covered in snow with several ice stalagmites protruding from their base. Underneath the ledges are large icicles, which appear to be rendered in 2-D. A smaller platform is present under the ledge on the other side of the cavern, and contains an Energy Tank as well as a tunnel in the wall that leads to a Morph Ball launcher, which propels up through the top of the ledge. Several Pow can be seen in the middle of the room, hinting toward the Energy Tank.

Navigation Booth BEdit


Navigation Booth B is the second Navigation Booth in the area and one of two connected to the ice bridge cavern. This one is accessed through a door on the lower floor of the cavern, behind a mound of ice. As with the other Navigation Booths, on the first visit the door to exit the room is locked until Samus uses the booth. On her first visit, using the booth populates more of the map and provides a waypoint to the next Navigation Booth. It leads into the frozen corridor.

Frozen door corridorEdit


The "frozen door corridor" is accessed from the lower ice bridge cavern's Navigation Booth. It is similar to other arcing hallways in the area. In the middle of the floor are two vault-able ice humps and above them, a Fly Pod that spawns Himellas until it is destroyed. The door is blocked by frigid ice that can only be removed with Super Missiles. To get around it, Samus can enter an open hole in the wall with her Morph Ball and roll through a tunnel. Halfway along the tunnel is a vent that blows air out at regular intervals; if she rolls in front of that while it is venting, it will blow her out into the room again. The tunnel leads out to the next room.


Kyratian corridorEdit

Main article: Kyratian corridor
Snowy area ice lake frozen Cryosphere HD

The "Kyratian corridor" is a room in Sector 2 / Cryosphere. It appears in Metroid: Other M. This room is located outside the facility found in the first few rooms of the Cryosphere. It is initially entered from a Morph Ball tunnel in the previous corridor, as the door between the rooms is frozen over with ice that cannot be destroyed without Super Missiles. The tunnel ends with a small blue ledge. The corridor is bordered on the left and right by snow-covered hills, with 2-D rendered icicles growing on their undersides.

Ice passage

The "ice passage" is a room in Sector 2 / Cryosphere. It appears in Metroid: Other M. The passage is a long, outdoor hallway that curves sharply to the right near its center. Similar to the previous outdoor room, the ground is frozen over and uneven with multiple ice humps that Samus can vault over. The ice in the floor appears to be partly reflective. It is surrounded by large misshapen branches, snowy banks and at several points, large canopies of snow hanging over the ground. Unlike the previous room, none of them will break when approached. Further on in the passage is a large wall made of ice.

The "Dessgeega chamber" is a room in Sector 2 / Cryosphere. It appears in Metroid: Other M. Samus passes through this room during her exploration of the Cryosphere in search of survivors. The chamber is a room divided by a large, raised section. The left side of the room has minimal features, and is inhabited by a small group of Snomers. A blast door is found on the left wall, with a red panel near it. It is likely that this is used to open the doors, although it cannot be interfaced with in-game. Where it leads to is unknown.

The "stalactite cavern" is a room in Sector 2 / Cryosphere. It appears in Metroid: Other M. The cavern is long and consists of icy ledges rising out of a river of ice water. The walls are formed of ice, with icicles and frozen runoff hanging off of them. Light from an unknown source can be seen pouring into the room through gaps in the outer walls. In the center of the room is a large bank of snow, which protrudes slightly from its lower half. On the other side of the lake is another shore, which contains the exit. To cross the room, a number of hanging stalactites (referred to as pillars in Metroid: Other M Premiere Edition) must be knocked down using Missiles, similar to stalactites found in the Phendrana Drifts during Metroid Prime. The energy attacks used by two Kyratians in the cavern may also knock down some of the stalactites.

Navigation Booth CEdit


Navigation Booth C is the third Navigation Booth in the Cryosphere. In contrast to the previous two Navigation Booths, this one has the booth on the right side of the room. As before, Samus must use the booth before she can proceed to the next room.


Junction accessEdit


"Junction access" is a straight, frozen corridor inhabited by Himellas and Snomers. There are two ice humps that Samus can vault over; the first is in the middle of the room and the second is near the exit door. There are six vents which release cold air at regular intervals, three on each side. The room leads into the "dead Gigafraug junction".

Dead Gigafraug junctionEdit

Gigafraug deceased crysosphere samus hd

The "dead Gigafraug junction" is a room in Sector 2 / Cryosphere. It appears in Metroid: Other M. The room is a partially frozen corridor with several fans blowing air out of ventilation shafts. One of the fans is permanently frozen over and never moves. In between the fans are thin buttresses lining the walls. The junction connects to three other rooms, each through a door located in a short alcove in three of the room's corners. The door leading to an environment with heavy gravity, and ultimately Sector Zero, is located in this room on a higher ledge. It cannot be opened until Samus has the Seeker Missiles later in the story.

Cooling fan hallway

The "cooling fan hallway" is a room in Sector 2 / Cryosphere. It appears in Metroid: Other M. The hallway is a long, straight room with a metal walkway. It has been severely affected by the climate control system's malfunction, with ice growing on parts of the architecture. The hallway is lined with buttresses, large pipes, a sliding platform and a track on the left side. There is a long pipe within the ceiling as well. Towards the back of the room is a pair of cooling fans blowing extremely cold wind, and above them is a control booth.

The "vast ice cavern" is a room in Sector 2 / Cryosphere. It appears in Metroid: Other M. This room is set inside a natural ice cave, with the only man-made architecture consisting of a ladder and a drain from the adjacent Water Tank. The entrance is situated on a higher ledge with a tower next to it, which surrounds a short ladder. In gameplay, this ladder is ascended as a series of Grab Ledges. At the bottom of the room is a snow-covered ground with a small, shallow pond near the right side. The water has a noticeable purple glow, produced by shadows from the ice in the room, and is populated with Skulteras.

Water Tank

The Water Tank is a room in Sector 2 / Cryosphere. It appears in Metroid: Other M. As the name implies, the primary feature of the room is a central tank filled with water. There are two ledges on either side of the room for Samus to climb up. Parts of the ceilings and walls are shown to be frozen over with ice, due to the malfunction of the climate control system. It can be presumed that the water temperatures would trigger hypothermia in the standard human, although this is not a concern for Samus in her Power Suit.

"Booster corridor access" is another arcing, connecting corridor between the Water Tank and "Speed Booster corridor". Most of the room is intact, with the only frozen part being the floor. There are two ice humps near the center of the room.

Speed Booster corridorEdit

Speed Booster corridor

The "Speed Booster corridor" is a room in Sector 2 / Cryosphere. It appears in Metroid: Other M. Visually, the corridor is unremarkable. It is long and straight with a very tall slope about halfway through the room. Along the corridor are multiple arches, and rectangular blue lights mounted on the ceiling and walls. Underneath the wall lights are smaller, red-colored lights that give a slight illumination to the surrounding walls. Multiple sections of the walls have four horizontal lines in them that appear to be grooves.

Short arcing corridorEdit


The "short arcing corridor" is entered from the Sector Generator Room. Aside from a snow hump near the exit door, this room has nothing of importance.


Storage accessEdit


"Storage access" is an upside down L-shaped corridor. Near the entrance, there are several square, red lights at the base of the walls. Around the corner and toward the door are several ice mounds that can be destroyed with Missiles. Doing so and clearing the room of enemies is necessary to cross the gap in the next room, as Samus must run into it from this room while building up speed in order to Shinespark.

Specimen storage roomEdit

Specimen storage room

The "specimen storage room" is a room in Sector 2 / Cryosphere. It appears in Metroid: Other M. This room is set in an indoor facility that also houses the Sector Generator Room, to which this room is connected via a hallway. To the left and right of the room are six large, glass specimen tanks that span the height of the room. They are filled with Snomers and Himellas, which are in stasis. The liquid in the tanks appear to be giving off carbon dioxide, as bubbles constantly flow up in the tanks. Each tank has a set of cables at their apexes, and are surrounded by barriers at their base.

Navigation Booth EEdit


Navigation Booth E is the fifth Navigation Booth in the Cryosphere. The camera is positioned so that the room is horizontal, unlike the previous Navigation Booths in the area. Use of this Booth is required, and also necessary for the Groganch and RB176 Ferrocrusher battles that lie ahead.

Experiment FloorEdit

Main article: Experiment Floor
Experiment Floor - center

The Experiment Floor is a room in Sector 2 / Cryosphere. It appears in Metroid: Other M. The Experiment Floor is a snowy location set on a cliff, outside of a research facility. The ground is uneven and several sections of it are raised. Near the entrance is a trio of snow-covered cliff platforms, which make a "staircase" of sorts. In the center of the area is a series of rock formations, curiously formed in the shape of arches, which extend over the room. Additionally, there are curved spikes of rock, and snow can be found falling from the walls and higher cliffs.

The Materials Storehouse is a room in the warehouse area of Sector 2 / Cryosphere. It appears in Metroid: Other M. Materials are transferred to and from this Storehouse via the nearby Materials Transfer Lift. As the name implies, this room is used as a warehouse to store unknown materials used by the ringleaders of the BOTTLE SHIP. The room is entered from a higher floor with observation windows allowing the room to be seen. There are noticeable icicles growing on parts of the walls, perhaps due to lack of maintenance, or the sector freezing over. A staircase attached to this floor allows passage to the lower floor. Hundreds of large blue, red and gray storage containers are situated in the room, forming a maze of sorts.

Small hallEdit


The "small hall" is a very small hallway accessed through the Multi-Lock Blast Shield in the dead Gigafraug junction. It can only be accessed when Samus has obtained the Seeker Missile power-up. It leads into the section of rooms with extreme gravity.

First gravity chamberEdit


The "first gravity chamber" is a large room. It starts as a short hallway, before opening into a larger chamber. There are two "steps" in the ceiling, including the ceiling above the beginning hall. When Samus passes the middle of the room, a loud roar is heard from afar, and the gravity in the room shifts, turning the ceiling into the floor. To cross the room, Samus must jump up the "steps" of the former ceiling until she is standing above the former floor, and Space Jump to reach the opposite site. The Space Jumps must be quick as Samus is not able to gain altitude with it, unlike in other Metroid games.

Second gravity chamberEdit


The "second gravity chamber" is an even larger room, where the gravity remains flipped on the first visit. It begins as a short hall leading to a drop shaft, which can be ascended (or under the gravity's effects, descended) with the Kick Climb. The shaft ends with a metal grate on the left side, which can be jumped off of. In the larger area of the room are several midair platforms, which contain Snomers. Samus stands on their undersides during gravity. There is a Missile Tank in a tunnel in the back wall, which can be reached by climbing up (or "down") to the tunnel entrance and rolling to the right.

Third gravity chamberEdit


The third gravity chamber, in contrast to the previous two, is a straight hallway with two gaps in the ceiling. One Baristute is found in the first, and two in the second. Samus is not required to kill them, but if she falls into the pit she may have to. To leave the room, Samus must Space Jump across the gaps.

Gravity L-shaped corridorEdit


The "gravity L-shaped corridor" is an L-shaped room with a raised walkway. As Samus approaches the turn in the room (marked by the raised walkway ending), the gravity becomes heavier, hindering her ability to jump.

Gravity passageEdit


The "gravity passage" is a long room and the second in the area with extreme gravity. In the very center of the passage are two columns spaced a short distance apart. The entrance and exits are each found through a trio of archways. The room is inhabited by FG-1000s near the entrance, Cyclaws in the center and an FG II-Graham near the exit.

Gravity pathwayEdit


The "gravity pathway" is another long passage that turns to the right. In the first half of the room are a pair of steps leading up to the turn. There is an E-Recovery Tank in an alcove in the wall, but it cannot be obtained until the Gravity Feature is self-authorized as Samus is not able to jump high while under the gravity's effects. There are two Kyratians in this room.

Fourth gravity chamberEdit


The "fourth gravity chamber" is a large room. At the end of it is a Kick Climb shaft, which can be reached by using a Grapple Point. At the top of the shaft is a pair of platforms, with a gap between them leading back to the lower floor. To get to it, Samus must quickly Space Jump while resisting the heavy gravity of the room. Another Grapple Point is found above the second platform. Samus can grapple to the left to reach a third Kick Climb shaft leading to a Missile Tank, or the right to reach a walkway with the exit at the end. It is recommended that Samus attempt to obtain the Missile Tank when she has activated her Gravity Feature, so that it is easier to climb the shaft.

Final gravity hallEdit


The "final gravity hall" is a straight passage that turns to the left (from Samus's perspective; the back from the camera's), where Samus drops down a step and is free of the extreme gravity.

Navigation Booth accessEdit


"Navigation Booth access" is a simple corridor leading to the penultimate Navigation Booth in the Cryosphere.


Navigation Booth HEdit


Navigation Booth H is the Cryosphere's penultimate Navigation Booth. When Samus uses it for the first time (as required), the map populates with the location of Sector Zero.


Nightmare's RoomEdit

Main article: Nightmare's Room
Nightmare's Room

Nightmare's Room is a room in Sector 2 / Cryosphere. It appears in Metroid: Other M. At the top of the room, several cables power up a machine whose "tail" is visible. Just as Samus is about to exit the room, these cables supercharge the machine, and reveal the Nightmare, who manipulates the gravity to hinder Samus' actions, and then engages her. Samus fights a long and frustrating battle with the Nightmare, before its faceplate cracks, revealing its true face, and it slams into the walls and platforms in its death, before falling to the ground dead.

Transport to Sector ZeroEdit


The "Transport to Sector Zero" is the elevator that leads toward Sector Zero. There are few unique features to the room, which has striped wall architecture and two branching "prongs" on either side of the elevator. A computer screen with a blue display is found on either side of the elevator, displaying unknown schematics. The elevator's interior is similar to that of other elevators on the BOTTLE SHIP.

Transport to Cryosphere SouthEdit


"Transport to Cryosphere South" is the room connected to the above. Unlike other elevator rooms, the camera in this room turns to an isometric perspective, as if it was a room in the 2-D sidescrolling Metroid games. This is because the door to the next room is found on the back wall (left from Samus's perspective). It leads into a Navigation Booth.


Navigation Booth IEdit


Navigation Booth I is the ninth and final Navigation Booth found in the Cryosphere. As with each of the previous Booths, the door to the next room is locked on the first visit until the booth is used. This ensures that there is a save point in case Samus dies during the coming escape sequence.

Light hallEdit


The "light hall" connects to the Navigation Booth and immediately proceeds the longer, arcing pathway that Samus later has to escape. As she runs through this room, numerous lights on the ceiling and walls begin to turn on, and remain active.

Sector Zero AccessEdit

Main article: Sector Zero Access
Sector Zero winding corridor HD

"Sector Zero Access" is a room in Sector 2 / Cryosphere. It appears in Metroid: Other M. Sector Zero Access is a long corridor formed in an arc. Like the short hall that precedes it, the room is initially dark until someone enters the room, at which point lights come in in rapid fashion. The lights extend across the length of the ceiling, walls and floor. There are five long pipes, one on the ceiling and two on each wall, that extend the entire length of the hall as well.

The "Sector Zero Entrance" is a room in Metroid: Other M. Classified in the map as part of the Cryosphere, it leads into the unexplorable Sector Zero. When Samus enters this room, the camera's perspective frequently shifts, showing different angles of Samus and something following her. After some time, she stops and automatically enters Search View. When she turns to her left, she is surprised by a Baby Metroid. Recoiling, she has a flashback of the baby from SR388 hatching (as depicted in Metroid II: Return of Samus and Metroid: Samus Returns). After hesitating, she prepares to kill it. However, she is shot in the back and collapses.

Transport to Main Sector SouthEdit


Transport to Main Sector South is the final room in the Cryosphere, and is accessed during the post-credits sequence when Samus is forced to take a detour through the Residential Sector. There are no unique features in this room aside from a glossy floor. The door to leave is covered by a Desbrachian gate. After releasing and killing the Desbrachian inside, Samus can go through the door to end up in the "fog-filled corridor".


Section 4 Gravity BlockEdit

Section 4 Gravity Block

Section 4 Gravity Block was a room in Sector Zero, in which MB's original body was stored. It is only seen in a custcene in Metroid: Other M. Samus never got to explore this room, since Adam detached the sector instead of her.
