It’s looking to be a hot summer on XBLA this year with squillions of excellent games heading our way and not a cloud in sight. Those lucky folks over at G4 got to grips with 3 XBLA games all pencilled in for a summer release and published this awesome gameplay video showing off cheery multiplayer Happy Wars, adventure-platformer Spelunky and the Kinect only Crimson Dragon. Microsoft’s hugely anticipated Summer of Arcade promotion is yet to be announced but you can join us in the guessing game and maybe even win some prizes here. Will any of these upcoming games make the cut?
