Digital Reality has just announced their next game co-developed with Grasshopper Manufacture, Sine Mora, is set for release on March 21 via Microsoft's Xbox Live Arcade.
Sine Mora is a dieselpunk shoot-em-up with a unique time manipulation mechanic. The game is said to play a lot like Raptor, Tyrian, and Raiden. Bosses in Sine Mora are unlike regular shoot-em-ups and are instead akin to platform game bosses.
The game runs through several difficulty levels and can be completed in 90 minutes on the easiest mode. Higher difficulties are said to last up to five hours, and collecting every achievement may take up to 50.
Sine Mora is exclusive to the Xbox 360. For now.
