Halo Charts 35 & Below hos a 4v4 Tourney MLG style tourney. They are looking for more players to create additional teams. The drafts have already taken place, but given enough interest, they will add some more teams. If you are interesting, go to Halo Charts and sign up for the 35 & Below Group for more information.

P.S. - If you couldn't tell by the name, you have to have a skill level of 39 or below to enter into this competition. If you are 40 and above, they have a separate group and tournament for that.
