**MONEY GLITCH** Every time you start a game, you get money at the start of the round. Max out the money for each round upgrade, the later the wave, the more the money. Start a game, get your money then quit immediately to the main menu. Start again, quit. Repeat as many times as you want and watch the money go up. -> [+] <- :)
First time I have played this game... YAWN. How this any different from Legacy Of Thousand Suns or the countless others???? I want something unique, not another clone.
