Inspired by the game of the same name.
I haven't played it, but I have seen the cutscenes to this game and they're very entertaining.
This is just my idea of what characters a sequel to this game should have.
BTW, I love the scout and so I chose him as the TF2 representative.
Characters belong to Valve, Steve Purcell, Mike Chapman and Craig Zobell, Jerry Holkins and Mike Krahulik.
