Halo Infinite multiplayer ranks
From Halopedia, the Halo wiki
The ranking system in Halo Infinite is primarily focused on a player's per-playlist Competitive Skill Rank (CSR), currently featuring no form of progression-based ranking. The closest alternatives to the progression rank systems found in prior titles come in the form of Halo Infinite's Battle Pass system, wherein armor pieces can be unlocked via challenges.
