Not really a compilation as such, just three old games banded together and available for a tenner, original packaging and all.
They're all conversions of coin-ops, and all first saw the light (heavenly choir) last autumn, but as games they couldn't be more different. Breakthru (Jan '87) is a remarkably tatty drive 'n' shoot which may have been a spanker in the arcades but is more of a slap round the chops on the Speccy. Kung-Fu Master (Sept '86) has all the usual flying limbs and oriental shrieks (zzz), while Crystal Castles is a cracking conversion of the old Atari Pac-Man derivative, well worth a tenner by itself as far as I'm concerned.
