Hey KChamp, We recently held a tournament on SSL and it went very well. Everyone thinks there should be a tournament mode and a prize for the winning team, like a weapon, theme, map, tank or kreds. There could be an entry fee to play in tournament mode like a kred to make it more interesting too. Let me know if you think it's a good idea or not.
Here is a good suggestion for 3 tanks or possibly 5, you should include free for all battle, everyone for themselves, also this might require additional maps for this mode.
