4. Splatterhouse
Hey, "violent" doesn't have to mean "good." Though Namco Bandai's remake of their classic 1988 beat 'em up was certainly lacking in the gameplay department, it did deliver on its promise to show buckets and buckets of blood. In fact, that game's experience system actually revolves around collecting the blood you've spilled from your enemies. One of the game's bonuses—called "splatter kills"—even involve performing extremely gory finishing moves.
The original game was pretty violent, but the new Splatterhouse takes this element of the game to a whole new, and much bloodier level. Hell, you can even lose your limbs and use your detached arms to beat up enemies. It doesn't get much worse than that.
Silly? You bet, but also gratuitous enough to nab the number 4 spot on our list.
