Decompression Chamber

The  is a location on board Mothership Zeta.

About
This is where you have to go after you've blown up the three generators in order to get to the upper saucer section. The entrance to it is next to the work bench of the engineering core and will be locked until all three generators have been blown up. There is a large button in the middle of the room that starts decompression. You'll need the astronaut's spacesuit while you're in this area or your head will explode soon after the pressurization begins. You find dead alien bodies scattered around after you leave the first chamber. The decompression chamber acts as an airlock between the spaceship and the space environment to lessen the strong vacuum effects when the air pressure disperses into space. It is a relatively small area compared to some of the other areas on the spaceship.

Notable Loot
Several Alien Atomizers, Disintegrators, and Power Modules, on the Alien bodies.

Appearances
only appears in the Fallout 3 add-on Mothership Zeta.
