A newly released video for TMNT: Smash-Up introduces us to a few new characters such as Casey Jones and what appears to be Krang. I know this game is being developed by the guys who made the fantastic Super Smash Bros Brawl, but I’m still a little leery on how it will play. I’m hoping that is does turn out well though. And who know what other characters we may see soon, maybe The Rat King or Zack the Neutrino.
