Containment was a multiplayer event for Halo Infinite that was held between August 29 and September 12, 2023. The fourth event of Season 04: Infection, Containment focused once more on the HAZMAT armor core, much like the HAZMAT event that kicked off the season. Containment would be followed by Tenrai III the week following its conclusion.

Containment content[edit]

Containment's content could originally be earned through a 10 tier event pass over the course of its two week tenure. Like events that arrived during the Winter Update, progress could be furthered through the completion of one of ten weekly challenges available to the player, or through XP earned by playing the game with the newly implemented "Match XP beta".

Helmet options earned through Containment would be made available on all armor cores during Season 05: Reckoning, with shoulder pad options following with the release of Spirit of Fire in January of 2024. Armor coatings earned would be made available on all armor cores with the release of Fleetcom in July of the same year. Rewards earned through Containment's event pass would be added to the Exchange during Haloween II in October of 2025.
