Skyfox was a big hit on the C64 - now it's available for the Spectrum. And a very workmanlike conversion the Spectrum version is too. The mainly monochrome graphics are effective. But the game, which is basically a fast-moving shoot-'em-up, lacks decent sound to complete the package.
The basic theme of the game is this. You are the pilot of a super-fighter Skyfox. Your job is to defend your bases from enemy attack.
Skyfox is a well presented game - but eventually becomes a bit boring after the umpteenth wave of tanks.
