Sony today sent over a new character trailer for Mr. Grimm that digs into his back story a bit. As you can see below, he does not appear to be the same character that we've met in the past. He's even more depraved and insane looking if that's possible.
Twisted Metal - Mr. Grimm trailer:
Twisted Metal for the PlayStation 3 is scheduled for a February 14th, 2012 release. Happy Valentine's Day!
