Description

Gameplay

The player controls a tank and shoots projectiles to destroy enemy tanks around the playfield. The enemy tanks enter from the top of the screen and attempt to destroy the player's base (represented on the screen as a phoenix symbol), as well as the player's tank itself. A level is completed when the player destroys 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 can destroy the base as well, so the player can still lose even after all enemy tanks are destroyed.

Battle City contains 35 different stages that are 13 units wide by 13 units high. Each map contains different types of terrain and obstacles. Examples include brick walls that can be destroyed by having either the player's tank or an enemy tank shoot at them, steel walls that can be destroyed by the player if they have collected three stars, forest that hides tanks in them, ice fields that make it difficult to control the tank and patches of water which cannot be crossed by tanks. In addition, flashing red tanks drop power-ups when destroyed. There are several types of power-ups, such as a clock that freezes all enemies, a protective shield, and a bomb that eliminates all on-screen enemies. The enemy tanks come in four different sizes, with the largest one requiring four shots to destroy.
