*excellent playability and fast action.
various levels and different gameplays.
Despite this, this game is not flawless :
Even the [[Commodore 64|C64]] and [[MSX]] ports , two machines often judged superior to Amstrad CPC in many ways, 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 as they were produced under license by Westerner companies, 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 behind too.
