hi i am hosting a halo 4 unofficial tournament my gt is sonOFaROOFER there will be no prize i may get my clan to come so that it see you all on Saturday 
You may have a lot of trouble collecting other players to take place in your tournament as there is no prize involved. I understand that the tournament is supposed to just for enjoyment, but in reality many people will wan’t something for possibly winning. I don’t wan’t to seem rude about this though so I won’t go too far. Though, you can try looking in the ‘Recruitment’ section of the forums as you’ll most likely have much better luck there. Good luck!
