Ninja Gaiden

Ninja Gaiden is an NES video game released in 1989 by Tecmo. While not the first installment in the series (an arcade game of the same name was released prior), it is more widely known than any other before it and was the first in the NES Ninja Gaiden series. The game was eventually ported to the SNES and the Wii's Virtual Console, among other systems not owned by Nintendo.

Gameplay
In all there are a total of six challenging sidescrolling levels that the game's protagonist, Ryu Hayabusa, will have to venture through. The character has a simple life bar which is at all times displayed at the top right of the screen along with the enemies' bar as well (if Ryu is battling one). Among other things seen up here is the level, score and timer. At the end of every act the player will be required to battle a boss, with six in all.
