The Grinder is an online cooperative FPS reminiscent of Left 4 Dead. You can play as four unique hunters that kill monsters such as vampires and werewolves. Expect light RPG elements. Apparently up to four players online with countless enemies on screen at once. Wii motion plus will be used for them having a Japanese assassin as a character. Expect all the bells and whistles from an online experience like Wii speak, leader boards, and achievements. Split screen co-op is an option for those without wi-fi. Expect a holiday 2010 release.
It seems to me that High Voltage justs looks at what is popular on 360 and makes a Wii version for us. Not complaining though.
