* GameBreaker: The grenade launcher. It fires quickly, covers a wide area of effect and goes through enemies like a lawnmower through grass.
* GoddamnBats: Meet [[ActionBomb Mr. Shrapnel]]; you ''aren't'' going to like him. He likes to explode, [[ExactlyWhatItSaysOnTheTin sending lethal shrapnel outward that travels outward to the edge of the screen]].
* DemonicSpiders: Meet laser firing orb; you ''really'' aren't going to like him. Not only can they zap you from across the room and glide at odd angles, they go flying away at high velocity when shot before they explode. They are still deadly before they actually explode, so the other player can shoot one into you if they aren't careful.
* MostAnnoyingSound: The High-Power Grenade Lobber - '''[=EEE=]'''''[=eee=]'''''[=EEE=]'''''[=eee=]'''''[=EEE=]'''''[=eee=]'''''[=EEE=]'''''[=eee=]'''''[=EEE=]'''''[=eee=]'''''[=EEE=]'''''[=eee=]'''''[=EEE=]'''''[=eee=]''
* 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. The SNES port deserves particular credit here. While it doesn't quite have the enemy density of the arcade, it has virtually ''zero'' slowdown, despite having massive quantities of stuff happening. When you turn on fast mode, you also discover that, most of the time, the game was actually ''limiting'' the processing speed. That's why it has no slowdown; the code is so fast that it has speed to spare in most cases. Some also regard the lessened difficulty of the SNES port as a point in its favor, making it much more playable while still being quite challenging.
* ThatOneBoss: Scarface and Die Cobros. Surprisingly, these two bosses are more difficult to survive than the Evil M.C.
