Aliens have infested Earth, and are spreading a deadly virus throughout the planet. Needless to say, they must be stopped, and fast. The time pressure (your score upon completing a level is based on the uninfected percentage of the land) is only one difficult aspect of this shooter.

Viewed in remote 3D with a patchwork-quilt type ground effect, with trees sticking out and full gravity. Controlling your spaceship involves balancing the direction and height as well as thrusting to the right speed. A scanner tells you where the aliens are.

Acorn Archimedes version

A demo of the game, still called Lander at the time, was bundled with new Acorn Archimedes computers.

Commodore 64 version

Despite frequent rumours, no C64 version was officially planned.

ZX Spectrum version

The Spectrum version started as a bedroom project, as Firebird did not believe the game was viable on 8-bit systems. It was not until Steve Dunn had written a demo of the ship flying over the landscape that anything official was signed.
