Fallout 3 - Mothership Zeta

Fallout 3 — Mothership Zeta is an add-on for the role-playing post-apocalyptic action game with a first-person view Fallout 3. A strange alien signal is spreading across the Wasteland Capital, emanating from a crashed UFO. Is this really a distress signal or is there something more sinister hidden behind it? The answer to this question becomes obvious immediately after you get on board a huge spaceship, with only one alternative — to fight your way to the command bridge and leave the ship.
