The Grinder is based in a world where monsters such as zombies, werewolves, and vampires are in existence and are a part of everyday life. A team is contacted and recruited by a contact only known as "Book" to keep the population of monsters under control.

Gameplay for PS3/360
The PS3/360 version of The Grinder will be a completely different game from the Wii version. Whereas the Wii version was a 4-player Left 4 Dead style FPS, the PS3/360 version is a top down shooter/hack & slash similar to High Voltage's Hunter: The Reckoning.
Doc: He wants to figure out everything he can about the monsters. Doc used to be a hunter but after a mission gone awry, he quit the hunting business to become a doctor. Now he has to come out of retirement to keep his three companions safe.
Miko: She is an assassin that just wants a new challenge. She was getting bored with her job until one of her targets turned out to be a werewolf, and she felt genuine excitement for the first time in years. Now she hunts them full-time to recapture that experience.
AJ: She is an urban explorer who had a bad experience and is looking for revenge. She was the only survivor of a slasher attack.
Hector: A greedy, boastful and arrogant bounty hunter who has tracked targets on both sides of the border. Hector used to be a professional hunter but he angered so many people to the point that professional hunting companies refuse to give him any more work.
High Voltage Software has previously worked on Hunter: The Reckoning and have said that The Grinder is heavily influenced by it as well as Left 4 Dead. The game will use the Quantam3 engine and the developers have said are trying to push the amount of characters on the screen at one time to its maximum limit. They are also attempting to make it have no load times. While the game has not been officially cancelled yet, development for both versions of The Grinder are on an indefinite hiatus. The game is currently rumored to have been moved over to Wii U.
The trailer released for the game in 2009 was voiced by actor Mark A. Sheppard (best known for his TV-work on Firefly, Battlestar Galactica and Supernatural) who also did the voice for the main character in High Voltage's Wii-FPS, The Conduit.
