There are 24 missions to play, multiple weapons, various enemies, hidden objectives, hidden map areas, and plain old fun. Nothing is perfect about the game, in fact most of it is mediocre but it is just flat out fun. I just can't stress that enough. Some areas require certain weapons like mortar to go over a wall, missiles for the helicopters etc. You can blow up almost everything with the unlimited supply of shells but other limited use weapons will do a better or quicker job.
Game uses the old drive over a power up mode for health and weapons.
When your tank is really hurting it will start to smoke. You can fire this game up, play a mission, get out that aggression and go on about your life. Nothing keeping you in there for hours. Of course it is pretty easy to play for hours too. I am trying to find all the bonus objectives in each mission.
