Monorail Skybridge: Facility Transport

Monorail Skybridge: Facility Transport is the twelfth level of Doom 3. This is where trash is processed in the UAC. The player is supposed to simply cross the Skybridge to reach the Monorail, but in a stunning move, Betruger makes the bridge crash, and thus, the player must go through Recycling - Sector 1. The Revenant is introduced in a cutscene, and this is the only level with toxic waste pools, in which the player has to fix a leaking pipe in order to move on in the level. The Rocket Launcher is found here.

Note: This level is also called Recycling - Sector 1.

Summary
As soon as the player tries to cross the bridge to the monorail, it is crashed by a demonic force, and the player has to quickly access a nearby airlock, after which they find themself in the first sector of the recycling plant. The player makes their way through the corridors, eventually reaching a large room where they're introduced to the new monster - revenants. Then they ride the elevator to a lower level which contains various maintenance facilities, eventually reaching a room where, due to a broken pump, the toxic waste blocked the path. To remove it, the player needs to go to the central processing room, climb the ladder up and find the console that can be reached by walking along the pipes to the platform it's on.

After shutting down the broken pump, the player proceeds further through more corridors, a cavern-like tunnel and a large room with floor covered entirely in toxic waste, but with a zig-zagged path across it. The player finds an airlock and has to go through another surface area. In it, the player has to quickly run to a small storage building, jump on some boxes and reach the catwalk which leads to another airlock, which in turn leads to the sector 2 of recycling.
