Defense Grid, developed by Hidden Path Entertainment (an indie developer which is currently developing Age of Empires II HD), revolves around defending power cores from marauding aliens who attempt to make off with them. You, the player, control a (wait for it…) defense grid on a series of abandoned military bases in order to stop the aforementioned aliens, which seem to be fairly generic. The real draw to this game is the great art – oh, and that it was part of Portal 2’s Potato Sack ARG, which means it’s got some juicy GLaDOS easter eggs for those rabid Portal fans out there, as well as a fully-featured DLC pack featuring the aforementioned maniacal AI.
