TL;DR
Halo Infinite's Season 4 brings back the fan-favorite Infection mode, where one team (Infected) converts enemy players (Survivors) to their team upon killing them. The mode has undergone some aesthetic updates, with Iratus, the Banished AI, taking control of the Academy's systems. Infection is a round-based mode where the goal is for the Infected to eliminate all Survivors. The last Survivor will have special traits applied to them, but their location will be revealed to all Infected.
