Today the demo for Firaxis' upcoming turn based strategy title XCOM: Enemy Unknown has been released.
The demo can be found on Steam, requires a Steam account, Windows Vista and 5.5 GB free hard drive space.
It should also be mentioned that there is still the possibility to get Civ5 for free (also as giftable copy) if you preorder XCOM now, and the number of preorders hit a certain threshold. There are a bit more than 2 weeks left, and the way to Civ5 is already to 50% done .

Thanks to Gyathaar, Rubin and Grifftavian for this news hint .
