Ninja Mission

Ninja Mission published and developed by Arcadia Systems in 1987.

This is an side-scrolling beat-’em-up game consisting of a succession of fights, in which you (surprisingly) play a ninja whose job is to go through the playfield and kill everyone in his path. You are also equipped with a dagger and a shuriken which you can hurl at your enemies.

You must also collect “idols” which are left lying around), which will reinvigorate you, as well as grant you further points. Once you collect all of the idols, you will have won the game.
