This is probably the best port amongst 8 bit computers, always referenced as by Amstrad CPC fans in the "8 bit war" when C64 users claim it to be a lame machine.
Even the [[Commodore 64|C64]] and [[MSX]] ports were somewhat inferior compared to the CPC version. The MSX version was named Contra as it was produced by Japanese company, while most westerner home computer systems had it under the Gryzor Brand-name, all of them being more or less approximate adaptations from the same Arcade game anyway. Perhaps not surprisingly, the MS-DOS PC version was miles behindtoo.
