Mazin Saga is essentially a beat 'em up with its own spin - the game turns the table into a fully-featured fighting game during boss battles. The game is inspired by the popular mecha series "Mazinger". While Mazin Saga doesn't excel in any of its gameplay genres, the variety found in its short playthrough made the game diverse enough to be memorable without relying on cumbersome bonus stages; part of the game has mechanics such as being chased by a giant T-Rex while dodging enemies, while other parts of the game have you fighting the many tokusatsu-inspired "Bio-Beasts", each level ends in a one-on-one battle with your one of your five mecha rivals, before facing the "Evil Mazinger" himself.
