So for some reason this old game came to mind and it's been driving me nuts. All I remember is there were several different colours you could pick from, purple green red and blue. You could also chang the skin of the screen, I believe one of the skins was american flag. Also you could teleport as long as you had some fuel you could move around the screen, on top of that you could get fuel tanks. The point of the game was to kill all tanks of another colour. Please I'm desperately waiting to play this game but can't remember the name. Thanks very much for any and all help. Ohh and last thing there were also ranks like colonel general and such.
