Historical game by Atari in which the player is the defender of three cities attacked by alien forces and other objects with some missiles. Moving with a trackball you have to neutralize all the shots using one of the three shooting positions, taking care not to end the ammo. Each level consists of one or more “waves” of missiles. The game ends when all three cities are destroyed by enemies.
The cabinet in the collection is produced under ATARI license by SEGA for the Japanese market (even if the game board is ATARI). It is a rather rare version even if the game is very widespread and appreciated.
