List of rooms in Metroid: Other M/Bioweapon Research Center

This is a list of rooms in the Bioweapon Research Center 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 Biosphere==
"Transport to Biosphere" is the first room of the Bioweapon Research Center. The room is rectangular in shape, with a path on the floor curving between the doors into the elevator and the next room, which is a Navigation Booth. In the middle of the wall between the doors is a shaft of yellow-tinted lights, with smaller lights embedded into the wall with triangle-shaped borders.
As Samus is returning to this room, a cutscene shows Ridley's clone heavily wounded in the "killing ground", as a massive creature appears and kills him.
==Navigation Booth A==
Navigation Booth A is the first Navigation Booth in the Center. Using the booth unlocks the door and allows Samus to continue. Her map does not populate with new rooms, unlike other booths, since Adam is not in contact with Samus at the time.
==Laboratory access==
"Laboratory access" is a curving corridor that connects from the booth to the main laboratory. It is an initially straight corridor that twists to the left. Along the way are two sections, perhaps security gates, with barriers on the floor that Samus can jump or vault over. On the first visit it is empty, but when Samus revisits the center after Sector Zero, several FG-1000 and two FG II-Graham units are present. Four of the FG-1000 units form two electrical barriers, which Samus can jump over, or remove by destroying the robots with her Plasma Beam.
==BRC main laboratory==
The "BRC main laboratory" is the central room of the Bioweapon Research Center. It appears in Metroid: Other M.
Items

==Storage room==
The "storage room" is a room in the Bioweapon Research Center. It appears in Metroid: Other M in a pre-rendered cutscene, and is not playable.
Items
:• none
Connecting rooms
:• BRC main laboratory (locked door)
==Spare room==
The "spare room" is a large, square room accessible via a staircase at the front of the main laboratory. It can be visited after James Pierce's body is found on the second visit to the laboratory, or after the credits. The room's back wall has a red hue from a pair of power sources. A Missile Tank is located in the top right corner. After collecting it, the door locks and Samus is ambushed by a group of fifteen Super Zebesians. Once she defeats them (most easily with the Screw Attack), the door unlocks and she can leave.
==BRC transport==
The "BRC transport" is a small room with an elevator that brings Samus to the lower part of the Bioweapon Research Center. It is found behind a door at the back of the main laboratory, which is guarded by a Desbrachian shell on the first visit. By the time she returns, the shell is gone. The transport elevator takes her to lab reception.
==Lab reception==
The "lab reception" is the room that the BRC transport leads to. From the elevator, the room turns to the right (shown vertically in-game), under an arch to a larger room. Ahead is a raised section of floor with a short staircase in front of it on the right. There is also a longer staircase behind the left wall, which has transparent window panes, leading to a higher door. On the right wall is a large screen displaying information. It makes a chiming sound, the same heard in the "Main Sector lift hub". The floor and ceiling have a tiled pattern.
It leads into the killing ground from the front exit, and into "operations base access" via a door on the left, reachable by staircase. That room cannot be accessed during the first visit as the door is locked. As Samus approaches the killing ground door on the first visit, the camera zooms in on her. On return visits, the room is inhabited by three FG II-Graham units.
==Killing ground==
The "killing ground" is a room in the Bioweapon Research Center. It appears in Metroid: Other M.
Items
:• none
Connecting rooms
:• Lab reception (automatic door)
:• Breeding cage (automatic door and blast doors)
:• Rinka corridor 1 (automatic door)
:• Short passage (automatic door)
==Rinka corridor 1==
"Rinka corridor 1" is a long hallway accessed through the door on the right side of the killing ground. After a short flight of stairs, Samus comes to a long hall with a locked door at the end. Along the walls are dormant Ring Beam Units. To unlock the door, Samus must shoot a sensor above it. Doing so activates not only the door, but the Ring Beam Units, which begin to spawn endless Rinkas. They continue to spawn on return visits.
Notably, this room contains the only sensor found in the Center, and the last one encountered in the game. It is not necessarily the last one activated, however, as some cannot be used until the Wave Beam has been authorized.
==Rinka corridor 2==
"Rinka corridor 2" immediately follows the first. It is a passage that curves to the left. Rinkas spawn endlessly in this room as well, but they can be ignored.
==Rinka corridor 3==
"Rinka corridor 3" is the third corridor with Ring Beam Units spawning Rinkas. It is short and straight. A Multi-Lock Blast Shield is found covering the exit door, and while Samus can destroy it easily, the cramped nature of the room means that Samus may get hit by Rinkas.
==Rinka corridor 4==
"Rinka corridor 4" is the fourth and final corridor with endlessly spawning Rinkas. It is similar to the previous corridor, but longer. The door is blocked by another Multi-Lock Blast Shield. As before, Samus must destroy it without being hit by the Rinkas to continue.
==Arcing hall==
The "arcing hall" is an empty corridor with a sharp arc to the left. It leads into the second Navigation Booth.
==Navigation Booth B==
Navigation Booth B is the second and final Navigation Booth in the Center. Using the booth unlocks the door and allows Samus to continue to Room MW.
==Staircase==
The "staircase" is the final room before Room MW. As the name implies, the primary feature of the room is a large staircase to the door, which is positioned on the back wall and angled right. Part of the floor consists of a transparent material, through which cables can be seen. When the room is visited for the first time, eerie music plays, which continues into Room MW.
==Room MW==
Room MW is a room toward the rear of the Bioweapon Research Center on the BOTTLE SHIP. It appears in Metroid: Other M.

==Short passage==
The "short passage" is accessed through the leftmost door on the back wall of the killing ground. After destroying the Queen Metroid, Samus pursues the survivor she saw in Room MW through this hall.
==Control room access==
:For the room on the G.F.S. Valhalla, see Control Room Access.
"Control room access" is a room shaped like a blocky L. It has a glossy, tiled floor that makes a unique sound when Samus runs across it. The same floor is found in the main laboratory. It leads directly into the control room, where Samus encounters the real Madeline Bergman.
==Control room==
The control room is an expansive room in the Bioweapon Research Center. It appears in Metroid: Other M and is where the final confrontation against MB, or "Melissa Bergman", takes place.

==BRC operations base==
The "BRC operations base" is a room in the Bioweapon Research Center. It appears in Metroid: Other M.
