This week's Xbox Live Gold deal of the week is none other than Geometry Wars: Retro Evolved 2. The game is normally 800 but is now on sale for 400 .
Packed inside it's shapey goodness is four player couch co-op play through a variety of game modes, including my favorite Pacificism. We reviewed the title some time ago, but still find ourselves picking up and playing it from time to time. For $5 this game is an absolute steal.
