Rank as you knew it in Halo 3, is dead. The concept of Rank has been revamped and divorced entirely from Trueskill and the concept of EXP (at both the Global and Playlist levels) has also been discarded and been replaced by The Arena.

The Arena is a brand new Matchmaking experience incorporated into Halo: Reach and aimed directly at competitive players who value skill, rank, and bragging rights above all else. Halo: Reach will still feature a wealth of other Playlist offerings, ranging from social to competitive (and everything in between), but the Arena is all about extreme competition.

Its rules are simple:

1. Play enough games each day and you will receive a Daily Rating.
2. Earn enough Ratings in a Season and you will be placed in a Division amongst your peers.

At the end of each season, everyone who has qualified for a Season Rating will receive a breakdown of their Division placement and their individual performance in each Arena Playlist.

Good luck. You’ll need it.
