The observation deck is a location on board Mothership Zeta.
The observation deck is a room with a large glass floor through which the player character and any surviving companions witness the aliens firing the death ray towards Earth. Initially, it is accessed from the space walk. Later, one can teleport to/from the observation deck and the engineering core.
Below the observation deck's glass floor, in the center of the room, which is facing earth; one can see what appears to be the East Coast and Central America extending down below Florida and upwards north of Canada. Including this, one can make out the Great Lakes and Michigan.
- This is one of many areas of the ship that will not be accessible after the player character has completed This Galaxy Ain't Big Enough....
- If one has good Karma and takes off their spacesuit before the starting chamber is pressurized, they will receive negative Karma from killing themselves, and vice versa.
