Summer of Arcade ends with Dust: An Elysian Tail, but cool XBLA releases continue after the promotion. Klei Entertainment's Mark of the Ninja, a unique side-scrolling stealth-action game, will launch on September 7.

Klei "really wants" to follow the XBLA release with a PC version, the developer tweeted. However, no definite announcements have been made toward that goal, so XBLA is currently the only place to hide in a vent, shoot out a spotlight with a shuriken, and then silently dispose of nearby guards. Legally, anyway.
