Fun Fact: The NES version of Rush 'N Attack was the only version to feature a two-player co-op mode.
Developer Konami dealt heavily in arcade games and ported many of them to the NES, including Rush 'N Attack.
The game was kind of ridiculous if you think about it. The player was attacking ostensibly-Russian military bases (hence the title) with nothing but a combat knife, dodging bullets and stabbing enemy soldiers as the opportunity presented itself, and only once in a while getting lucky and finding a dropped weapon to use. The ridiculousness of the premise didn't make Rush 'N Attack any less fun.
