The first map will be pl_borneo. It's played the first team to win two halves (one half = you play once on each side.) The home team, #1 Intercollegiate TF2 Team ,gets to choose the side they start on in the first half. In the second half you mirror that (e.g. first half you started on attack, so second half you start on defense.) If a team is tied after the first two halves (1-1), then the away team gets to choose what side they start on for the third half.
