Zombies returns as the cooperative multiplayer mode for Black Ops 4. The game mode features a wider range of customization, allowing for more personalized play styles. Mechanics of the game can be customized via "Custom Mutations", which include over 100 variables, such as overall difficulty, zombie speed, health, damage, and more. Time-limited events known as "Callings" are also promised to be included in the game for long-term engagement. Similar to the Nazi Zombies mode in Call of Duty: WWII, custom loadouts are included to allow players to select different starting weapons, equipment and special upgradable weapons, as well as perk selection to be available in each match. A new game type, Rush, is introduced into Zombies, where the players build up points and multipliers and compete against one another for the highest point possible until death. Black Ops 4 features a new form of consumable items called Elixirs, which grant temporary buffs to the players upon activation; and Talismans, special modifiers that are applied at the start of each match. Elixirs are provided in five types: Classic, Common, Rare, Legendary and Epic; the first is unlocked permanently via player progression, while the latter four are consumable and only craftable using the in-game currency. Talismans are also consumable, and can only be acquired in the same method.
