X-Com: UFO Defense
Commander Jonelle Barrett is determined to win. Having moved from Morocco to a new base in Switzerland, she is well-placed to build a fortified base and defend Europe from the marauding aliens who harvest humans as lab animals for breeding stock . . . and for their dinner tables!
Barrett soon finds that her new territory is already riddled with alien invaders. Her handpicked garrison is all she has?until she learns that one of her most trusted people may be a traitor. Her task is twofold: keep the aliens at bay and keep her own sanity in the face of despair. She doesn't know which will prove more difficult.
