This is a shoot-'em-up arcade-style game in 3D. Simplicity and immediacy make it most attractive, and youngsters will probably find it compelling.

Astride your laser-armed superbike you must chase the machines of the warlords through the forests - your only enemies are the trees! You have three lives per game.

There are eight sectors, or levels, each one being more densely forested than the last. You must successfully patrol each sector by day and night to be promoted to the next.

You have control over your speed, which way you turn and photon bolt firing. All this via Kempston stick or keyboard.

The picture projected is good and jerkiness minimal. The trees race forward to meet you most realistically. The target bikes serve this way and that.

The instructions are minimal (all on cassette insert), the game loads easily and runs very quickly yet is quite controllable, even by keyboard.

As I said, its appeal is in its straightforwardness - possibly so much so that lack of variety might eventually make it pall.
