If you have Marathon, you can join the TPC (the Pf0r3) clan. It is very new. It hosts any Marathon game you have. We are planning to make allies with the Big 3 (Maw, TUI, and HMC). Once we get eight people, we will host free-for-all challenges and will crown the person with the most wins. Once you become a clan member you can have the TPC tags next to your gamertag. The first to people to join that have Marathon and Marathon Durandal will be in charge of one of those games. If you want to join, just search The Pf0r3 clan on the group search, and if you have a question, just post it here.
