XCOM: Enemy Unknown is introduced by Lead Producer Garth DeAngelis in this E3 2012 gameplay demo. XCOM: Enemy Unknown is an RTS and has two major gameplay modes, as explained in the video. Players build their own base in XCOM to research new items, weapons, vehicles, and units. Each room can have its own benefit in or out of combat, too.
XCOM: Enemy Unknown requires strategic unit placement in this turn-based combat system. Group tactics are also key to victory, says Garth DeAngelis. The game is set for release for PC, PS3, and Xbox 360 on October 9, 2012.
