 The game was released in Canada, Europe, Australia and Brazil, at a time when the Master System was discontinued in other markets.The controls and rules of the game are very different from the original "Shinobi".Although the objective of the game is still to reach the end of the stage and then fight a boss, the player is prevented from proceeding onwards at certain points of each stage until certain enemies are eliminated, similar to a side-scrolling beat-'em-up.
