2K Games announced today that a free demo for XCOM: Enemy Unknown is now available on Steam. PC gamers can now try out the hybrid strategy/tactical game that pits players against an unknown alien threat. The demo includes two levels of the single-player tutorial campaign, covering combat controls and tactics. Players will also get a chance to see the XCOM base, where they will train soldiers and research alien technology.

Video of the demo, like that seen below, has already hit the web, so even if you aren’t a member of the “glorious PC gaming master race” you can still experience what XCOM is all about. 2K has said a demo will be available “soon” for Xbox 360 and PlayStation 3 gamers.

XCOM: Enemy Unknown will launch on October 9th, and those who pre-order the game will be eligible for free exclusive downloadable content, including soldier customizations and a recruit unit inspired by the original X-COM: UFO Defense.
