|Tractor Beam for the 16K ZX81:
This Galaga style game features most of the game elements found in the arcade version. Aliens fly onto the screen to assemble their attack force. A special master alien on the top row can use his tractor beam to capture one of your ships. Don't let him get away with that! Shoot him down next time he's attacking, reclaim your ship and dock two of them together to double your firepower. Also features four selectable difficulty levels and three unique challenging stages. Shoot down all forty aliens in the challening stages to get a special 10,000 point bounus. Extra life for every 50,000 points.
This game will run in colour and with sound using a Chroma interface and a Zonx sound board, but will also run on a standard ZX81.
