Warzone

Warzone is a multiplayer gametype introduced in Halo 5: Guardians.

Overview
Warzone 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, or by capturing all three bases on the map and destroying the enemy team's core, located in their base. 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. A contingent of AI-controlled Marines aligned with either team is also stationed in each base. There are armories and garages on the map that can be captured by the players to give access to superior weapons and vehicles, respectively, and are part of the game's new Requisition system.

The Requisitions available to the players are determined by their energy level, which is accrued over the course of the game, as well as the REQ cards they have purchased or earned by leveling up their Spartan Rank. The requisition packs allow players to respawn with a certain weapon or in a vehicle of their choosing, with a higher energy level providing access to more powerful items (although the player must also possess the REQ card for that item). Warzone is the only multiplayer mode in the game allowing the use of non-cosmetic Requisitions.

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 base 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.

Six maps will support Warzone at launch while another six will be available as DLC.

The mode is tied to the Halo series fiction as a type of War Games Spartan training simulation. It features opening and closing cutscenes and Spartan Commander Sarah Palmer in the place of the Arena multiplayer announcer. Some of the maps built for Warzone have been said to be four times larger than those in prior Halo games.

Warzone Promethean and Covenant enemies' difficulty is heroic, but due to the great amount of players, their health and AI are improved, making them stronger than the standard Heroic ones.

Warzone features two new spawning systems. The first system ensures players spawn on capturable Warzone Bases. This system uses spawn points placed in three groups called "rings". The first ring is made up of spawns placed inside the base. These are the highest priority spawns that are most commonly selected by the engine when the player selects the base as a spawn location. If there is combat inside the base, however, the engine will ignore spawns in the first ring and instead evaluate spawns in the second spawn ring. This second ring is comprised of spawns placed just outside the base. The third ring is the failsafe ring and contains spawn points significantly further away from the base. The spawn engine will only spawn players in the third ring if combat around the base is so chaotic that all spawn points in the other two rings are suppressed.

The second system, called "bro spawing", finds groups of players using clustering analysis to understand who is working together as a team. Each set of players is then evaluated to determine if it's suitable to for a player to join by looking at a number of factors: confidence level in group directional heading, number of players in the cluster, combat status and enemy player presence. Once a compatible cluster has been identified, spawns are generated dynamically around that group.
