Your mission in this combination of shooting and math game is to control a purple tank out to wreak havoc in Battle Town. However in order for your shells to have effect on the enemy, you must first answer a maths question in a time limit. Different types of enemy require different types of maths questions to be answered. Answer fast enough and you will be awarded an instant reload. Use the ARROW KEYS to move around. Press the SPACEBAR to fire. When prompted use NUMBER KEYS to enter answer to questions and press ENTER to submit the answer. Good luck!
