Comes out this month.I played the multiplayer demo on xbox live.So basically you have an arm that you can grapple and pull yourself to poles and branches n ect,and can either climb up or swing and throw yourself further,you can also grab players and pull them too you.The graphics arent that impressive though and the battles feel like every gun you get your just shooting little red pellets at different speeds (slwo for shotgun,fast for machine gun,ect).Its hard to even see the difference in the weapon your holding.I wasnt very impressed.Seems more like an arcade game honestly and not something I would spend $60 on.The retail version maybe better but...I highly doubt it.
