Ok, I've seen some pretty unfair things in this game, but three cars with mounted guns and a light tank still seem like overkill at wave 20, how desperate is this german commander anyway?
At first I sucked at commanding him, but by the end I was pretty good and for the people who cant find what button to press, it's space and it says it right there under the game.
one thing... make the destroy button anything other than the right mouse button, my computer thinks I want to open the little options thing and then the game thinks that I'm always holding the right mouse button. I guess the right mouse button shouldn't ever be used in a game...
