Alpha Labs - Sector 2: Union Aerospace Science Division

ALPHA LABS - SECTOR 2 - "Alpha Labs Sector 2 processes and stores hydrogen fuel through the facility's primary system, the Molecular Fuel Storage Compactor. The sublevel section houses the coolant control system needed for proper hydrogen fuel refinement."

Alpha Labs - Sector 2: Union Aerospace Science Division is the sixth level of Doom 3. Once again the player must continue their way towards the Alpha Labs to quickly meet up with Bravo Team. There is a short glimpse of the Marine squad through a window, suggesting the player is not very far. This is where the dark labyrinth with the lantern-welding scientist is located. Trites make their first appearance soon after the first web sighting in the exit room.

Walkthrough
At your arrival, you are "greeted" by a lot of Medkits and a levitating corpse you won't be able to follow. After that, the player will crawl a lot in this level. The first time is a access vent from the water closets (there is no "mirror scene" in this one). On your way, you'll be able to observe, through a grid, a Zombie eating a Fat Zombie's rotten guts. Once you drop down from this vent, there is no return, so collect all plentiful ammo and medkits there are at the beginning of the level. Just before reaching what is presumed the first part of the Molecular Fuel Storage Compactor, you will see the Bravo Team running through a window, albeit unable to communicate with them. Sergeant Kelly will then assignate the next objective: connect with Bravo Team in Sector 3 of Alpha Labs. The Marine then has to make his way through the dark labyrinth of the coolant section, where a scientist guides him with a lantern. The Chaingun (among other bonuses, such as Backpack) can be acquired here. Then, there will be another crawling section, which is another point of no-return, before the final trial of this level (and perhaps the hardest so far, so it might be a good idea to save here): the Trite Room. The best way to survive seems to stay at under the ladder case (between the computer and the wall) and use the Chaingun. If needed to reload, switch instead to the Machine Gun. Once all the Trites are eliminated, a ladder appears. There are some more Trites in the upper area. Just open the door to the left, run into it, and either gun the Trites from here or directly exit the level.
