Rank (Halo 4)

Spartan Rank is the primary ranking system used in Halo 4. Players are promoted after accumulating an amount of experience points (XP) through multiplayer (i.e. by playing War Games and Spartan Ops, completing Commendations and Challenges) and Forge matches. After reaching level 50, players are allowed to earn specializations.

Competitive Skill Rank, or CSR, was a secondary ranking system based on wins and losses rather then XP. It was designed to pair players with similar skills into the same match. After its launch date on April 10, 2013, players' CSRs could be seen on their Halo Waypoint stats until that functionality was removed in November 2021. Each playlist featured its own individual CSR running from levels 1 through 50. Following the shutdown of Xbox 360 Halo online services on January 13, 2022, the CSR system ceased to function.

Spartan Rank

Players begin their careers in the base SPARTAN-IV ranks. There are 130 ranks in total, from SR-1 to SR-130, unlocking armor permutations, Loadout equipment, tactical packages, support upgrades, visors, stances and emblems and weapon skins. After achieveing SR-50, players are able to select a specialization from the eight available. A specialization consists of a path of ten ranks, with various unlocks exclusive to that specialisation. Once the player has hit the tenth rank of the picked specialization, they can pick another; this process repeats until all specializations are completed at SR-130.

CSR

Competitive Skill Rank, or CSR, was a new system introduced to Halo 4 in April 2013 aimed to fill a similar role to the 1-50 skill rank systems seen in Halo 2 and Halo 3. CSR calculations were calculated-per playlist, with the highest CSR value for a player being the one shown on their Halo Waypoint service record.

Competitive Skill Rank was calculated in one of two ways, depending on the playlist. Several playlists used a win/loss system to determine ranking, while others utilized individual scoring, which determined rank based on the player's performance against everyone in the match, teammates included. It was also affected by the CSR's of the other players in the game: outperforming and beating players with higher CSRs would make a player more likely to rank up, and vice versa. Playlists that utilize individual scoring allowed players to rank up faster than those that used team scoring.

The playlists that utilized individual scoring were:

• Infinity Slayer
• Big Team Infinity Slayer
• Rumble Pit
• Multi-Team
• Team Action Sack
• Flood, Team Snipers
• Regicide
• SWAT

Team-based scoring playlists were

• Castle Team DLC
• Team Objective
• Capture the Flag
• Dominion
• Team Throwdown
• Team Doubles
• Grifball

Gallery

• 

  CSR emblems representing the various levels. The blank emblem means the player has not played the playlist since April 10, 2013.
