'''Gryzor ''' was a port from the '''Arcade ''' game '''Contra ''' from '''Konami'''.
(Also known as Probotector on Nintendo Entertainment system)
== Gryzor Vs. Contra Vs. Probotector ==
As said, '''Gryzor''' is actually a port from Konami's '''Contra'''. Contra was often renamed from countries to countries and system to system for more or less obscure reasons.
Contra was renamed '''Gryzor''' because the term '''Contra''' could refer to "the Iran-Contra affair" or "Nicaraguan Contra rebels"... which were hot international political topics in 1987.
