The game, originally scheduled for an April release, is coming out on May 18, and will feature six different characters from different fields.

I might pick this game up at some point, if it ends up being another good co-op game. I have New Blood, which my sister and I were playing through co-op, until we got to an operation we couldn't complete (or rather, there was a rhythmic action she couldn't perform, she's bad at rhythm). That game was pretty tough, I kind of hope they tone down the difficulty a bit.
