Just played the demo, it was short (come on, they didn't even let me fight the boss, or have the second part of the first stage with the elevators in it?) but it was pretty much the same thing as the NES version, right down to the controls. I wouldn't have it any other way. Oh, it had a lifebar and I didn't have to worry about grinding to build up my HP in this version. I don't get why everybody's so upset at this game's controls/gameplay... I thought the original Bionic Commando was a universally well-liked game.
It's definitely getting a purchase from me next time I pick up an XBLA points card. Can't wait for Galaga Legions, but with the rate the Summer of XBLA is going, people are gonna get really hyped up, play the game and declare it's shite.
