Bionic Commando Rearmed
This is a very cool game, I checked out the demo last night. Based on the NES classic, you are a commando with a bionic arm and wreak havoc in the 2D world. The graphics are slick, the controls are tight and the game looks to be fun. The demo is a bit short to tell how good the main game is, but current reviews are looking great. Add the challenge rooms levels (50-something of them) and this is a good buy.
