Most speed tournaments I see are 2 player, here is an idea for say a 6 player game speed tournament;
Set up 6 player speed games, if you win the 6p game you progress 2 rounds of the tournament. If you are in 2nd or 3rd place in a game (rankings dictated by assasin=army count, terminator=last 2 to be put out and Standard=last 2 to be put out) you progress 1 round of the tournament.
You progress until there are only 6 players left, utilising a play off system at the end if there are say only 3 guys left to play a round before the final.
The final is a 6p game.
Also, if someone can run a tournament on Supermax Prison Riot it would be appreciated. It's a fantastic map for multi player but no one ever plays!!
