Sine Mora, the diesel-punk shooter with a time-bending gameplay mechanic by Grasshopper Manufacture and Digital Reality, now has an exclusive release date on Xbox Live Arcade. The date was revealed by way of a Facebook contest in which folks could try to guess the day the game would become available.

Joystiq notes that if you cross-reference the winner of the contest (revealed in the video below) with his prediction on the Facebook contest page, you end up with a March 21 release date.

Originally planned as a release for both Xbox Live Arcade and the PlayStation Network, developers Grasshopper Manufacture and Digital Reality decided to make the game an Xbox 360 exclusive back in December of 2011.
