Grasshopper Manufacture and Digital Reality are partnering for a second XBLA/PSN game, in addition to Sine Mora. Announced at a Grasshopper Manufacture event during Gamescom, Black Knight Sword is a side-scrolling platform action game that takes place in a sort of puppet play. The scrolling is made to look like the character is actually standing in place, and the background elements are constantly shuffled and replaced as if on a stage.
In the above video, taken by Gamer365, Akira Yamaoka introduces the game. It's like you're at the GHM/Digital Reality party yourself!
