Room of ...7 max?
Two players are randomly chosen to battle the other 5 are now the Xelnaga!!!
Every 5 mins up to 30 mins, a popup will show for the xelnaga to vote on a choice of 2 things. (like the red blue light band things.)
Because your in charge of this part you can balance it out this way. and you don't have one mod going absoloutly mad all the time just dropping stuff everywhere.
Also the Players get 1 help that they can call in that the Xelnaga can approve or deny (again red vs blue), if approved they do not get another chance.
At the end of the game, the winner stays in, the loser is on the Xelnaga team a new opponent is chosen and the process starts again.
