Halo Infinite is a 2021 first-person shooter developed by 343 Industries and published by Xbox Game Studios. It is the sixth mainline entry in the Halo series and the third in the "Reclaimer Saga" following Halo 5: Guardians. Infinite features a multiplayer component, with deathmatch, capture the flag, and other modes available in standard 4-versus-4 and Big Team Battle variants. In competitive Halo matches, there are four game modes that can be played during a game: Capture the Flag (CTF), Oddball, Slayer, and Strongholds.

All competitive matches are played four-versus-four and contain multiple different game modes within one match. To increase the intensity and skill-level competitive halo also removes the radar and gives each player BR75 Battle Rifle as their starting weapon. The competitive experience is therefore requiring more precise communication and expertise to maximize your own and your Spartans' potential.

In professional play, matches are typically played in Best of Five (Bo5) or Best of Seven (Bo7).
