The only complaint I have about this game is the fact that I have gone as far as wave 15 before I got a gun. This is an anoying problem because of the fact that the cannon is so under powered even with full upgrades (master firearms, faster fire, and faster reload) that it does not have enough of an impact to the monsters to get much father.
