Changes

The Home Computer's home computer ports (Amstrad CPC port tooincluded) were mostly produced under licence by the Famous amongst Amstrad CPC user [[Ocean|OCEAN]] , the company from Englandfamous amongst Amstrad CPC user for it's good ports.

As said, '''Gryzor''' is actually a port from Konami's '''Contra'''. Contra was often renamed from countries country to countries country and system to system for more or less obscure reasons.

Nintendo Entertainment System (NES) console version was renamed '''Probotector''' in Europe, having the sprites changed from humans to robots due to censorship reasons, political authorities judged it was too violent for European children if the protagonist were humans, and would lead those kids to kill peoples people in the street.

Despite those name changes, this is the same game despite in different countries, on different machines and regardless of country or machine or being produced by different companies (under license in OCEAN's case).

Gryzor is probably one of the best game available on Amstrad CPC, and is probably featured in every Top10 ''Top 10'' games for this standardsystem. This is of course not objective but quite accepted amongst the Amstrad community, . Gryzor is the symbol of what a well programmed CPC can do. This is a "Run and Gun" style game, such as games like : [[Robocop]], Midnight resistance... With vertical, horizontal and 3d (sort of) action.

*Quite Faithfull Being quite faithful to the arcade 's colourful graphics exploiting . It exploits CPC's mode 0 very well the Mode 0.

This In CPC owner's view it is probably the best port amongst 8 bit computers, and stands up well against the other 8-bits in a fair comparison. It is always referenced as such by Amstrad CPC fans in the 8-bit wars. 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.

UnsurprisinglyEven 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. Unsurprisingly the MS-DOS PC version was miles behind too.

The engine code is similar to [[Renegade's]]. This is expected because it was written by the same programmer[[John Brandwood]].
