And no one has commented on this yet. Shows the current interest in TF2 from SpA (An observation, not a criticism)

Personally I think this new game mode sounds interesting. Puts the entire balance of the game both on display and trial at the same time. Eager to see how it works...though I think it might have to be on another server...

Yeah, they probably did. This doesn't change the fact that a Highlander match with a bit of organisation is a whole lotta fun (spa vs comm *hint* *hint*)
