Rank (Halo 5: Guardians)
A player's Spartan Rank, or SR, is based on experience points earned by playing matchmaking and completing Commendations. There are 152 ranks in total, from SR1-SR152. The higher the player's rank the better REQ packs they earn. A breakdown of the SR rank requirements is found here: Boop
A player's competitive skill rank, or CSR, is not only based on wins and losses but also the rank of the opponents the player faces on the enemy team. Unlike Halo 4, which had its CSR be numerical values from 1 to 50, Halo 5: Guardians' CSR is a league system. There are seven divisions for the CSR, with the first five having six tiers. These include Bronze, Silver, Gold, Platinum, Diamond, Onyx, and Champion. However, before players can be placed within a division they must first play ten matches in order to be properly placed. The amount of points players gain or lose depends on the people they play against. For example if a player has been placed in the Silver division and loses against a team of Gold players, they will lose rank less than they would have if they had lost to someone from a lower Division, such as Bronze. The same goes for winning – if a player beats a team of Bronze players, they won’t rank up as much compared to when they beat a team of Champion Players. Losing games will cause a player's progress within a rank to decrease, but will never drop down a whole rank from losing. Like Halo 4 each playlist has its own ranks.
While the first five divisions do not have a numerical value attached, the Onyx and Champion divisions do. Players within the Onyx division are ranked 201-3,000 while Champions are ranked 1-200. Players in the Onyx and Champion divisions cannot share the same rank, IE there is only one player with the rank of 185 in Team Slayer in the world. If a player wishes to rank up they will cause other players to lose rank similar to a leaderboard.
Seasons are a new monthly competitive feature for Arena where a players CSR is reset in select playlists. This feature gives players a chance to improve on their performance from the last season and earn cosmetic rewards.
