If you've got a hankering for a delicious layer of squad-based strategy in your tower defense sandwich, but you have issues with commitment, you'll be pleased to know that you can now try out a demo for Anomaly: Warzone Earth. We have the file available for download, or you can grab it for the PC and Mac through Steam.

The game takes tried-and-true tower defense concepts, and mixes in Commander powers, vehicle units, and unit upgrades. It costs $8.99 on Steam, but that price is set to go back up to $9.99 after the launch sale period. Check out our recent review for impressions on the clever strategy hybrid.
