The fun you can have with helicopters, eh? In this game, you lift off in your whirlybird and scroll around an underground base, blasting missile silos and alien attack waves, and picking up fuel drums and the odd extra gun. Knock out the enemy completely and you get to play "Catch The Missile" with their secret weapon.
Getting that far is another matter though, because all three versions are very tough. The missile-spitting ground emplacements are the real boogers because of the difficulty of aiming AGMs while your chopper is fighting the laws of gravity. Once you've mastered that, it's quite addictive - but three quid is all it's worth.
The prettiest of the lot, but a wee bit slower than the Spectrum version, so it's not quite so playable.
The fastest and most playable version, in spite of it having a bit of a wobbly chopper.
Smart music and shiny sprites, but a cramped playing area, makes it even harder to dodge aliens and missiles than the other versions.
