When this Mature-rated game came out for the generally kid-friendly Nintendo Wii console, it definitely turned a lot of heads. And while it wasn’t a huge commercial success, this Sin City-inspired black-and-white-and-red action game was a lot of fun for teenagers and older audiences. You could even get your motorcycle in on the carnage, catching enemies and dragging them behind you while you spun wheelies over their flattened domes. Brutal!
