The game has a very DoubleDragon-esque feel to it, which for me is a complete flashback to the good old days. It’s very easy to play and EXTREMELY fun as well. On my N1 the controls are just point to move and trackball to nuke. If you haven’t already, head on over to www.getjar.com for some pure mobile pwnage! The game is only free until the 29th of October.
