Battle City Tank 1990

The player, controlling a Tank, must destroy enemy tanks in each level, which enter the playfield from the top of the screen. The enemy tanks attempt to destroy the player's base (represented on the map as a bird, eagle, or Phoenix), as well as the human tank itself. A level is completed when the player destroys all 20 enemy tanks, but the game ends if the player's base is destroyed or the player loses all available lives.

Note that the player tank's weapon can destroy the base as well, so the player can still lose even after all enemy tanks are destroyed.
