Peachy implementation of that much under-rated arcade vehicle Moon Patrol; the hairiest ride outside of Disneyworld's Space Mountain.
Starfighter 7 has been grounded by alien laser-fire. Having survived the crash-landing (well, them's the breaks!), you must try and reach the safety of Moonbase Alpha in your trusty Model T Moon Rova. However, not only must you negotiate some ludicrously pock-marked terrain en route but you must also slug it out with those pesky aliens, who not content with wasting your starship, want to waste you too!
Although intrinsically simple in concept, the combined challenge of rocks, canyons and irrepressible attackers works on practically every level. High scores demand both strategic driving and defensive shooting! However, it must be said that the program's visual effects are rather dull. When I bust a buggy I want to see it *bust*! At least a couple of wheels should come bouncing out of the debris!
Dragon Data managed this to great effect on their splending Lunar Patrol program a while ago. The Spectrum buggy just sort of implodes. The Currah Microspeech routines are also rather uninteresting.
Unless more notable chat is buried deeper within the program, it seems hard-pressed to do more than count you in and out. Still, I'm nitpicking. Playwise this is neat stuff and, if I was you, I'd book a lunar lesson right away.
