Bad Dudes vs. DragonNinja is a platformer beat'em up that gained notoriety long after its release in 1988. This is due to its unique back story, whereby the president of the United States was kidnapped by ninjas.
This falsehood of this story becomes quickly apparent; your street-smart character plows through ninjas by defeating even three with a single kick. My own conclusion is that you're up against the world's worst ninja clan. How they've managed to kidnap the president is beyond me.
