Tank Battalion is an arcade game originally released by Namco in 1980. I worked with people at DJOG to recreate this game in processing.
You can move your tank arround using the arrow or WASD keys. And to fire, press the SPACE key. Your goal is to protect the flag from the other hostile tanks. On the right side of the screen you can see your score, your lives, the round number, and the amount of tanks left in this round.
