Trivia

 * To get the hidden Plasma Gun, the player needs to open "Ventilation Access Grate 3" through a touch-screen, located in a L-shaped console, on the right just after accessing a standard door (before the room with a lift). After opening the access grate, the player must come back through the door he just entered and immediately turn left; he should see some boxes and the ventilation access opened. First item in the ventilation duct is a medkit, then following the little conduit, the player must turn right, watching a room through a grate: shoot it (one shotgun shell should do the job) and the Plasma Gun is just ahead, on the pipes; then he can follow the pipes-road on the left to find other useful stuff, like armor shards.
