Despite its family-friendly aesthetics, the Nintendo Wii offered plenty of mature titles. Sadly, 'The Grinder' didn’t make the cut. Developed by High Voltage Software in the late 2000s, this 4-player co-op FPS was Left 4 Dead before there even was a Left 4 Dead. What set The Grinder apart was that it featured a garden variety of monsters that included vampires, werewolves, and yes, zombies. Unfortunately, the project was ultimately canceled due to a lack of interest from publishers.
