Observation Deck

The  is a location on board Mothership Zeta.

About
The Observation Deck is first accessed from the Space Walk and is a room with the large glass floor through which the player and any surviving companions witness the Aliens firing their Death Ray towards Earth.

After passing through the door near the teleporter that has inconveniently been deactivated, you will enter a large room. Immediately, you should notice two turrets firing at you from the ceiling. Additionally, a couple of aliens and a drone inhabit this room. If you head SW, you can find a small room on the right (open it via the control panel just next to it) that holds the Atomic Pulverizer, which is a slightly upgraded version of the Atomic Atomizer. The Pulverizer's best advantage is a dramatically lower AP cost. Atomic Atomizers can be used to repair the Atomic Pulverizer. Continue through this passageway, and you will come to a 3-way. Left is a blocked passageway, right goes to a flight of stairs. Go up the stairs and then take the first left. You will find yourself on the platform from which the aliens you first encountered in this room were targeting you. On this level there is a Healing Arch to the left and a control panel for opening up the next area. Be careful you do not jump into the area between this control panel and the rail as your character will become stuck. After activating the control panel, go south down a set of stairs from the platform and then proceed to a another alien/drone infested room via the east door. Continue on until you enter a room full of weapons and armor for the taking. LOTS of stuff in here and some Alien Captive Recordings. After your shopping spree, you can go through a door to the north and explore a hallway full of buttons to push and instant entertainment ensues. But to move onward with the mission, go to the SE door into the Experimentation Lab.
