Warzone

Warzone is brand-new multiplayer gametype exclusive to Halo 5: Guardians. It will feature large-scale combat with two teams of 12 Spartans facing off against each other on large maps populated by AI-controlled Covenant and Promethean enemies, including named boss units that occasionally appear on the battlefield. A team achieves victory by attaining 1000 points, which are gained by killing both enemy players and AI enemies. In the beginning of a match both teams are dropped to their respective bases via Pelican and have to clear the base of AI enemies. Some of the maps built for Warzone have been said to be four times larger than those in prior Halo games.

Another variant of the game mode is a Base Assault attack/defense scenario without AI enemies. In this variation, one team is tasked with defending each base on a map and the other team attempting to capture the case and push the other team back. The defending team must hold the base until a set time limit runs out. As the attacking team manages to capture each base, they force the defending team back and extend the timer until they assault the defenders' home base and must destroy their core.

The mode is designed to be tied to the Halo series fiction and features Spartan Commander Sarah Palmer in the place of the Arena multiplayer announcer.
