Battle City

Control your tank using arrow keys to move and Space to fire. Your mission is to destroy all enemy tanks in each stage while protecting your base (the eagle at the bottom). Enemy tanks spawn from the top and try to destroy your base. Collect power-ups that appear when you destroy flashing tanks: star (upgrade), shield (invincibility), grenade (destroy all enemies), clock (freeze enemies), shovel (fortify base), tank (extra life). Brick walls can be destroyed by both your shots and enemy fire. Steel walls are indestructible.
