The following is a list of room in Sector 2 (TRO) from Metroid Fusion.
center|400px
All the rooms in Metroid Fusion have explicit identification numbers visible through access with the Debug Menu. Within the Debug Menu, the values "H" and "G" are used to represent Samus's location on the BSL Station. The "H" Value represents which room Samus is located in, and the "G" value is used to represent the entrance Samus used in order to access the room. For the purposes of this list, the "H" value of the room will be listed first, followed by the "G" value of the first entry into a room, then the "G" values of other entrances in order of normal availability to the player. For example, the Operations Deck would be listed as "H014-G141 (G065, G027, G022, G193)".
If a proper name for the room exists, that name will be put first, followed by the room's "GH" value. Then a short description of the room will be given, possibly with a picture, as to allow for identification of the room. If the "G" value has a Security Lock over the Hatch, the "G" value will be labelled by a color corresponding to the Security Level if the door has a security level greater than 0. If a latent ability is required to use the entrance, an abbreviation for the upgrade will be placed next to the "G" value of the room, such as PB for Power Bomb or MB for Morph Ball. A majority of the room names are unofficial.

==Navigation Room Station 2==
The main Navigation Room for Sector 2 (TRO).
==Save Room Station 2==
The main save room for Sector 2 (TRO).
==Recharge Room Station 2==
The main Recharge Station for Sector 2 (TRO).
==TRO Main Research plaza==
The central hub to further rooms in Sector 2 (TRO). 
This room contains Zeros. After eliminating Nettori, the zeros will evolve into KiHunters.
==TRO west research hall==
A short hall west of the main research plaza. Houses mild jungle life. A hidden wall can be destroyed to uncover a door leading into a Sector transport tube.
This room contains . A Missile tank is located at the left end of the room, beside the Screw Attack wall.
==Northeast research hall==
A hall containing Zeros.
==Jungle security station==
A small jungle room connecting to further Sector facilities. Leads to the Level 1 Security room. Using the Screw Attack, a Sector transport tube can be found.
Contains Zeros that ultimately metamorphasize into KiHunters.
==Level 1 Security Room==
Room ID: 
This is the room that houses the Level 1 Security terminal. Once Samus activates it, all Level 1 hatches remain unlocked. Unbeknownst to her, the releasing of the hatches allows further X parasites inside the other neighboring Sectors (specifically Sectors 2 and 4). 
Late during her mission, Samus can return to this room and destroy a breakable wall NorthWesteard using her Screw Attack. This leads to a hidden storage room.
==Crumble City== 
Room ID: h055-g132
A hidden storage that can be access from the far left of the Security Room using the Space Jump and the Screw Attack. It houses one Energy Tank and one Power Bomb Expansion. To obtain both, carefully timed Space Jumps are required to move above a large formation of pit blocks. If quick enough after touching a pit block from below, Samus can still have time to recover using a well timed jump off a pit block. The pathway leading to the Energy Tank has some solid flooring underneath a few pit blocks, making aerial recovery not too difficult. 
The room's name comes from how almost the entire area is filled with Crumble blocks. Most players and fans who have traversed this area have labelled the room as Crumble City.
==Research storage room==
A small room sealed by a Level 1 Security hatch. A hidden cache can be uncovered behind a bobm block, with the cache area containing an Energy Tank.
==West research hall==
==Transit plaza==
A long hall leading to the Data Room.
After Samus obtains Bombs, the doorway leading back into the Main plaza becomes destroyed by a SA-X. This forces Samus to detour underground to escape the room.
This room contains a Missile Tank. It is located directly above the destroyed door. Samus must use her newly acquired bombs to uncover the small area.
==Transit Save Room==
A Save room located underneath the destroyed doorway's connecting hall.
==TRO Data Room==
Room ID:
The Data Room in Sector 2 (TRO) containing the Morph Ball Bomb data. Samus reaches inside this room once she has unlocked the Level 1 Security Hatches.
==Botanical maze==
A tall shaft room housing many bombable areas, forming a maze. Samus uses a combination of bombs and Morph Ball to proceed through.
This room contains Zeros. A Missile Tank is located in a hidden area Northwest of the room. To find it, Samus must bomb a floor to reveal a rising pillar, then locate a breakable wall she can climb into with her Morph Ball. Once in the hidden room, Samus must use her Bombs to reveal another rising pillar. Using that , she can climb to reach the Missile Tank at the top of the area.
==Transfer shaft==
A tall shaft with mechanical background and flooring. There are no platforms save for the large edge between doorways. Once Samus drops to the ground floor below, she cannot return back up without the Hi-Jump Boots. No enemies are present.
==Jungle chamber==
The first room Samus explores to contain thick vegetation. Samus must bomb a floorboard to continue forward. This room contains a Desgeega, Zeros and a Blue Zero. A Missile Tank can be obtained on the southeast corner of the room, using bombs to reach it.
==Flora Cave Access==
Room ID:
A small room right of the lower Save Room. 
This room contains 3 Owtch.
==Zazabi's Room==
Room ID:
Main article: Zazabi's room
This is the room where Zazabi is fought. Samus can return here after obtaining the Screw Attack to reveal a breakable wall leading into a hidden subchamber (which leads to two weapon expansions).
==Zazabi's Subchamber==
Room ID: h056-g134
This room is accessible through Zazabi's Room and only by use of the Space Jump and the Screw Attack. Here, Samus must use well timed Speed Booster movements to reach the Power Bomb tank in the corridor above her. She must first charge up a Speed Boost, stop, and carefully jump up above a small ledge with a Shinespark ready, then release said shinespark towards a ramp to maintain the speed momentum. She must do this repeatedly until she runs straight through a breakable wall leading directly into the Power Bomb tank (this may require trial and error to obtain). She then can exit to the left where a set of four Pit blocks await.
A hidden Missile Expansion is also located in this room's left corner. It requires Samus to charge up a shinespark from the bottom elevation, then accurately aim at a small wall towards her right side to obtain. The blocks, as well as the expansion, can be revealed using a Power Bomb for easier planning. 
==Access to Main Deck==
==Service hall to Main Deck==
==Root Hall==
Room ID:
==SA-X Escape 2 Room 2==
Room ID:
*Pre-Nettori: h057-g136 (g137)
*Post Nettori: h061-g143 (g144)
==Shutter Hall==
Room ID:
*Pre-Nettori: h058-g054
*Post Nettori: h059-g082 
The Shutter Hall is a room Samus passes through during her exploration in Sector 2 (TRO). She first arrives here during a chase sequence from a SA-X. She needs to quickly hit the shutter lights in order to proceed and escape the SA-X's pursuit. Samus can then enter the left room to escape from the SA-X's sights and end the chase sequence.
There is a hidden path in this room that is mandatory to discover in order to find the source of the Reactor Silo's roots. Close to the left room's entrance is a hidden missile block located on the floor. Shooting it and the hidden shot blocks underneath it reveals a small tunnel towards a winding hallway leading out to the left and the rest of Sector 2 (TRO).
After Netorri's defeat, this room contains three winged Kihunters and one grounded Kihunter (Two winged ones are located near the shutters while the third winged and the wingless one are near the hidden winding hallway). The large roots below the shutters dissolve, making backtracking into the Reactor Silo possible.
==Panic Room==
Room ID: h060-g140
The Panic Room is a small one-way storage-like room with only one major significance. Its name comes from the time it is visited; during the second TRO SA-X chase sequence. Despite being important to the chase sequence, this room is entirely optional and can be avoided all together using speed-running tricks.
Samus can come across this room during her escape from the SA-X. This room appears to be a dead end but contains a small ledge for Samus to grip up and enter into a small tunnel using her Morph Ball. If this room is entered during the Chase sequence, she will have only a few seconds to reach the leftmost edge of the room before the SA-X enters (unlike the previous rooms, the SA-X does not enter this room almost immediately). If successful, the SA-X will enter slowly, look around and walk out of the room unable to locate its prey. Once the chase sequence music stops playing, the SA-X has successfully left the area and Samus can exit out of this room to continue exploring Sector 2 (TRO). 
There is a small hidden Morph Ball tunnel located above the wall's right edged grip. It will lead Samus to a pit block above and closer to the entrance from which she came from. This tunnel appears to serve no significant purpose other than a somewhat alternate escape path from the SA-X. After Nettori's defeat, this room will contain 2 Reos and, if Samus continues towards the enclosed leftmost area of the room, X parasites will begin to fly into the room, a pair of two at a time for a total of six extra free floating X Parasites to be absorbed.
==Jungle Shaft==
Room ID:
==TRO Recharge Room==
Room ID
A hidden Recharge Room located near the Jungle Shaft, directly above the door leading into a cave of Kihunters. To locate it, Samus must simply stand on the right ledge jutting out from the wall and use her Morph Ball to hug the right wall. She will immediately pass thru a wall and enter this room. Due to restoring Auxilary Power, this room proves useful to Samus after her long journey through the Reactor Silo, and before her dangerous trek into Nettori's room. This room is entirely optional to visit but is here in case of an emergency.
Because there is no clear identification that this room exists, it is nearly impossible to find and almost always overlooked, leaving many to stumble upon this entirely optional room by accident. 
==Jungle Cave==
Room ID:
A large room filled with many roots, vines and KiHunters. It is within this room that Samus draws near the source of the many large roots flooding in the Reactor Core. The initial hallway is flooded with large roots, making straightforward travel somewhat difficult. However the end of the right side of the hall has a door that will be powered down due to the root problem. So Samus must seek elsewhere to search. Above the left door is a small shaft leading to a higher elevation of this room, the hall above flooded with many vines entangling a few KiHunters. Past here, a Gadora blocks the open doorway to the boss behind the powerful overgrown roots.
Samus must revisit this room after Nettori has been destroyed. Because of the boss's defeat, the roots overgrowing inside the hallway will disperse, allowing for an easier walk out, with only the remaining KiHunters to be concerned over. The long hallway is perfect to charge up a Shinespark if need be. 
This room contains KiHunters. On the initial visit, there will be a Gadora present.
==Nettori's Room==
Room ID: 
Main article: Giant root's arena
This room is the source of the roots choking the Reactor Silo. It is here Samus must explore in order to restore power back into the Silo (and as a whole, the entire B.S.L station).
This rooms contains the Nettori-X along with its associated components (2 Samus Eater Buds and 3 Samus Eaters).
==Jungle Service Corridor==
Room ID:
A hall infested with many Kihunters inside small enclosed portions of the room.
==Jungle Storage Room==
Room ID:
A E-Tank is found in the hidden back of this room, far to the right.
==Jungle Hall==
Room ID:
A plain short hall containing 4 wingless Kihunters. Samus can access this room once Nettori has been defeated, and acts as a shortcut out of Sector 2 from her current area, which naturally would be just outside Nettori's area.
This room contains 4 KiHunters with their discarded shells laying about.
