Those hoping to engage in wanton shape genocide without a console's involvement can now look towards Valve's online game distribution service, Steam, now hosting a Windows XP version of Geometry Wars: Retro Evolved. Developed by Bizarre Creations and considered by many to be the Xbox 360's first must-have game, Geometry Wars is being offered at an introductory price of $2.50, half that of its 2005 "supposed to be free" launch price. The game will be shifted to $3.95 starting June 22.

If Steam isn't your thing either, perhaps this holiday season's Geometry Wars: Galaxies on the Wii and DS will be enough to enlist you in the fight against circles and diamonds. Failing that, we'll have to conclude that you're one of them -- a total square.
