We at the PBCup are going to try and make as many demos available to the public from each Playoff match.
Last night Rust and aB squared off in the 1st round of the playoffs. If you don't know the outcome, then I wont spoil it for you, but some teasers include a nail biting first round on castle1 and a well fought, close game, on the tie breaker (midnight).
