wealth of new content not seen in the PSP version.
The included content includes new levels, several of which were originally designed for Twisted Metal: Black, access to an online soundtrack, an art book, a 30-minute making-of documentary, a new "Sweet Tour" mode, and ending footage originally shot for the first Twisted Metal game. Oh yeah, and the port of the PSP game is in there too, with an improved framerate and textures.
Considering the game will retail for $19.99 USD, that's a whole lot of content included. TM:HO-ETE is scheduled for a February release in the States.
