If you read GamesRadar (which they can now prove you’ve done at least once), you probably know DeathSpank is a downloadable action RPG. You know it’s funny, thanks to the input of developer Ron Gilbert, one of the guys behind the original Monkey Island games. You may know it’s hitting PC, Xbox 360 and PlayStation 3 in mid-July, and you may have sussed out that it’s set to last about 15 hours. Hey, you’re pretty smart. But what you don’t yet know about it co-op mode.
