Left 4 Dead Rules
Teams will be of either 3 or 4 players (depending on total numbers of participants). Players will be allowed to choose ONE other player that they want to be on a team with. Assuming teams of 4, pairs/individuals will be randomly assigned together to try to keep the teams even. EX: if there are 2 pairs of people and 4 people not in pairs, one pair will be placed with 2 individuals and the other pair will be placed with the other 2 individuals.
Anything except circumventing a crescendo event is legal.
Round 1: Blood Harvest Versus campaign. Highest-scoring teams advance
Round 2: No Mercy Versus campaign. Highest-scoring teams advance
Round 3 (if needed): Death Toll Versus campaign. Highest-scoring team wins.
EDIT: I am trying to figure out a way that we could add the new playmode, Survival, as part of the tournament; I was thinking have each team play the same survival map (lighthouse?) and using the times as like a ranking system to determine seeds? I dunno just a thought.
