This game works on a ZX81 16k RAM (b/w and no sound), but also has support for Chroma colour interface and the Zon-X sound card. This is Battlezone for the ZX81, and like the arcade version it is in 3D, however the tanks do not move or shoot. Only the homing missiles are a threat to you. You can select to play on two difficulty levels - Two homing missiles are coming at you on difficulty level two, but only one on level one. The level is over when all tanks are destroyed. You can blow up the cactus’ for extra points.
The game has no ending, it is a high score game, and keeps playing forever.
It was released in 2023 by Bukster Games.
