This game. This fucking game is so hard, yet so addictive. Basically, your goal is to, with random troops and equipment that you can also level up, evacuate the civilian population, or in the optimal situation eliminate the zombie threat. Its hard to explain, its like trying to keep pure water away from oil, with guns and explosives. Maybe these will help explain it: http://img710.imageshack.us/img710/7836/atomzombiesmasher201111.jpg http://img830.imageshack.us/img830/7836/atomzombiesmasher201111.jpg http://img600.imageshack.us/img600/7836/atomzombiesmasher201111.jpg http://img404.imageshack.us/img404/7836/atomzombiesmasher201111.jpg http://img717.imageshack.us/img717/7836/atomzombiesmasher201111.jpg http://img171.imageshack.us/img171/7836/atomzombiesmasher201111.jpg http://img7.imageshack.us/img7/7836/atomzombiesmasher201111.jpg http://www.youtube.com/watch?v=UtgHpIfTCb8 Did I mention the soundtrack is awesome, if a bit repetetive?
