AWESOME game
hey everyone, the combo system works fine like this. when you place 2 turrets next to each other and upgrade them a great deal, they will begin to shoot differently on occasion. example. with the rockt and the laser, occasionally a rocket will be fired that flies around and shoots extremely deadly lazers at the monsters... much like an auto turret. it works for other weapons too, i believe if you use the lightning gun with the lazer, it will make a slowig turret. etc.
