The Citadel

The year is 2321, Earths population has spread out into space. Mega-corporations have built space stations throughout the galaxy. You have not long arrived on-board a Citadel class space station owned by the Federal Defence Union (FDU). The main function of this Citadel is scientific research and development. The night you arrived, the stations Artificial Intelligence (AI) was beginning to malfunction. And now, only one week later, the Citadel's main power has just shutdown, and the backup generator has come online. The doors won't open, communications don't work, and you can hear some unusual noises from other parts of the space station. Can you escape before the backup generator goes offline and you're trapped on-board forever?
