From outer space you receive a call for help: due to a technical problem spaceship 'Haven' is in serious trouble. You and Jameson are sent out to solves these problems and help any possible survivors. Search for 'key cards' that contain important information. In the spaceship there are evil aliens walking around, averse to any outside interference: they're out to kill you and your buddy, so take good care and shoot them down before they attack you!
Use WASD or the arrow keys to move around. Use the mouse to aim and to shoot. Press the spacebar to perform actions (open doors etc.) and Shift to select a weapon.
