Spacewalk

The station has been overrun. You have two pistols, a safe room, and one shift to get the numbers up.

HOW IT PLAYS Choose a 5, 10 or 15 minute shift and step out of the safe room. Aliens hunt you room to room through the station's corridors, hangars, reactor and decks. They scream when they spot you and you can hear their footsteps coming from behind. Every kill counts. When the clock hits zero your shift is scored: aliens killed, your best for that level and shift length, accuracy and headshots....
