It’s Halo week and to celebrate there’s a whole host of things going on in the competitive world of Halo. It’s not all about new maps though, finally we see the return of TrueSkill. Similar to Halo 2, the much requested skill ranking will represent your abilities in each of the playlists. Play well and it increases, receive a whooping and it decreases.

Just like its Halo 2 counterpart, the CSR (Competitive Skill Ranking) is from 1-50, players who manage to reach level 35 during Halo week will receive an exclusive Avatar tee.
