The psycho clown and all the glorious car combat is coming back. Here's the E3 video from Gamespot. I'm not so sure about the way there taking it but I wont pass judgment till we see more.
It does kind of scare me that they at first were not going to include a single player. *-* WTF were they thinking! Thank PIE that someone hit them with a stupid stick and they will be adding it. Also a shame it's only coming out on the PS3, I so do love my achievements. ;) But all in all I've been waiting for another TM tital and it's about time they deliverd. >:P
