Well, looks like I'll be playing Super Time Force all over again when it hits Steam. Why? Well aside from the new challenge levels and alternate-dimension powers, there's three new playable characters. Two of which are from Team Fortress 2. Well from the looks of it at least. One is the Pyro, and the other is the manly Saxton Hale fisting his enemies to death.
Fisting all over the place he is.
