While the next Ratchet & Clank game looks handsome enough in those new bright and cheery screen shots, the PlayStation 3 exclusive had a gorgeous base on which to build. This is a sampling of that concept art from Insomniac Games' Ratchet & Clank: All 4 One.
Cute, menacing, atmospheric, it's all here. Some of this stuff might even serve you well as your new desktop wallpaper, should you be a fan of Ratchet & Clank.
