A demo for XCOM: Enemy Unknown is now available on Steam, as PC gamers can finally check out Firaxis' take on the classic series. Console gamers will get the demo "soon," which likely means when the PlayStation Store and Xbox LIVE Marketplace update this week.
XCOM: Enemy Unknown's demo weighs in at a rather hefty 5.7GB and includes two levels from the tutorial. That should be plenty to convince people whether or not Firaxis has done the series justice, but considering the tier three reward on the Steam page is halfway to unlocked, many haven't needed an extra push. Still, the demo can give a taste of the alien-killing, laser-shooting, and fragile squad members that go hand in hand with an XCOM game.
If the demo gives an error when you try to download from Steam, restart the client to solve it. XCOM: Enemy Unknown arrives in full on October 9.
