* PolishedPort: Of course, the game was notorious for being NintendoHard. The home console version wasn't exactly easier, but with unlimited continues meaning you could play it without spending a fortune in quarters, it was certainly more enjoyable. One advantage it has over the arcade original is an actual soundtrack; in a developer interview, the sound engineer for the arcade game was instructed not to put too much effort into the music since the game's constant gunfire and explosions would drown it out anyway.
* [[ThatOneBoss Those Two Bosses]]: Scarface and Cobra Head. Surprisingly, these two bosses are more difficult to survive than the Evil M.C.
