Zombie Rush

Zombie Rush is a playable gamemode featured in Call of Duty: Black Ops 4 Zombies. In Zombie Rush, up to four players compete against each other in order to obtain the most amount of points by the end of the game.

Overview
Zombie Rush is a fast-paced intense mode that forces players to stay in certain areas around the map in order to gain points. Killing zombies without being damaged will increase the player's multiplier, allowing the player to earn more points at a faster rate. There are also special coin drops that appear at the beginning of a rush and at the end, which helps the player maintain their multiplier, which will slowly decrease if the player does not kill zombies or collect the coin drops. After each rush, the player will be tasked with traversing the map to the next location. If the player is unable to reach the next rush area before time runs out, the player will begin to take severe damage until the player either makes it order goes down, which will then teleport the player to the next rush area.

In addition to this, all purchasable items are free; the Mystery Box will be available at all its possible locations, as well as the Pack-a-Punch Machine. However, there is a cooldown for every use of the Mystery Box or Pack-a-Punch Machine, although players will receive items from these devices at an faster rate, even if the player does not have Timeslip. Players are also unable to acquire alternate ammo types from the Pack-a-Punch Machine, and are forced to only upgrade the same weapon once.
