The evil Neo Zeed who has aspirations of world domination had your
sensai assassinated, and your girlfriend Naoko kidnapped. It's time for
you to fill the shoes of Joe Musashi a ninja master on his quest to
avenge the death of his master, and to save his girlfriend from the
evil clutches of Zeed.
Let's get this straight.
Revenge of Shinobi is a tough game. It's very unforgiving, and it's not for
the gaming weak. RoS has you taking revenge in eight super challenging
side scrolling levels that require exact timing and a whole lot of
patience. I'd liken Shinobi's play style to a Castlevania where perfect
timing and finesse is everything. Even Shinobi's double jump requires
exact timing which makes it feel imprecise at times, but it's mastery
is a must, especially in the later levels of the game. Missing a double
jump can result in a lot of frustrating deaths for the player. However,
that aside, the rest of the controls are spot on, and even the double
jump becomes second nature after a while.

The gameplay is simple, move from one side of the screen to the
other while dispatching hordes baddies while dodging their attacks, and
learning their attack patterns. The game not only tests your gaming
skills, but also your you memorization skills. Every boss has an exact
pattern, and until you learn it, the bosses will destroy you. My
suggestion for anyone interested in this game is to look up youtube
videos that show you boss strategies. A lot can be learned from
watching those who have mastered the game.
While the gameplay is really hard for newcomers, especially with the lack of checkpoints, and tough boss battles in each level, the game is totally learnable for those with the patience to see it through. The game takes total concentration from the player. Like many other games like it RoS requires you to get in your hardcore zone. Finally mastering a challenging level that was seemingly impossible for you to beat before puts you in gaming zen which few games ever help you reach. It's immersion is in mastering the game.

Bottom Line: Revenge of Shinobi is a great, but challenging game. If you don't have oldschool style patience, then stay away, because the game will frustrate the hell out of you. However those with patience will be totally immersed in Shinobi's gameplay.
