Joined at the hip for release on PC is Shank, a real bloody platform game from the mind of Cloning Clyde's Klei. They're both digital only releases.
DeathSpank originally was just for Xbox 360 and PS3 but Hothead Games and Ron Gilbert said they just couldn't ignore the outpouring of requests from the PC crowd, and so they joyfully relented to give us the RPG adventure styling’s of DeathSpank.
Shank meanwhile is a platforming, 2D side-scrolling marathon full of spurtings of the deep red stuff. Both are available for £9.99 on Steam should you fancy them.
