OK here are the 'levels' and then character descriptions will follow while I think them over. Don't expect TOO many new vehicles, maybe a couple, just warning you now.
1-Suburban Terror: Based on the TM: Lost level, a demented neighborhood.
2-Montreal: It's cold here and the drivers are bound to freeze in this chilling area. Why Montreal? Because, let's face it, we've been waiting for a TM level in Canada for a long time (just kidding)
3-Paris: It just wouldn't be Twisted Metal without a trip to Paris
4-Las Vegas: What happens in Vegas stays in Vegas...but as soon as the drivers arrive here, what's happening in Vegas won't be staying...
5-Minion's Stadium: Based on the TM: Lost level 'Stadium Slaughter', you'll face the demonic one himself and his massive tank.
6-Egypt: Send the drivers to their tombs here
7-Transylvania: Same as the TM: HO level
8-Area 51: It really is Judgment Day as UFO appear in the sky...and attack the drivers!
9: Death Port: Based on the TM: Lost level, you learn that Calypso will meet the winner in Harbor City (trying to tie in the uncompleted game some way) and so the remaining drivers board this massive ship for one final battle
10: Piecemeal's Harbor: It seems the remains of the defeated vehicles have been shipped here...and built into a monstrous machine to face you!
OK so those are the levels and next will be characters, after that, I'll let you vote on whose story you want to hear first.
And trust me, Piecemeal will be badass here. I love Dark Tooth/Tower Tooth, but he's been used in plenty of fanfics and Warhawk I used in a old story. I wanted to try someone new.
In the meantime, I also found a fitting theme:
