Were you like me and highly intrigued with Relic and THQ's Warhammer 40K: Space Marine until you found out the co-op mode was more of a Horde mode instead of campaign co-op? But a nice low price can make a difference, and that's where GameFly comes in. The rental service/used game seller has both the Xbox 360 and Playstation 3 versions of Space Marine on sale for $9.99 with free shipping until 5 PM Pacific Time today. GameFly includes original materials like online passes in the games they sell, so don't worry about being locked out of multiplayer. What better chance to step into a space marine's bulky armor?
