In the upcoming online shooter Call of Duty: Black Ops 4, you will not only face other players in the Battle Royale mode Blackout. Zombies are also involved.
Traditionally, Battle Royale focuses on the fight between players. However, more and more shooters are incorporating PvE elements into the battles, such as Fear the Wolves. This is also the case in the Call of Duty: Black Ops 4 Battle Royale mode.

The undead are coming!
Will the zombie mode be mixed with Blackout? Not much is currently known about how the undead will fit into the Battle Royale mode Blackout of CoD: Black Ops 4.
The fact is: you will not only be fighting against other players on the large map. Zombies will also get in your way. However, you should not expect waves of undead to defend against. What is traditionally known from the zombie mode of a Call of Duty will be adapted for Blackout. More details are to come.

That’s why Black Ops 4 Blackout also has zombies: Battle Royale shooters generally play similarly. Therefore, players constantly ask themselves why they should switch to another BR shooter when it offers hardly anything new.
For this reason, developers must come up with something unique for their own Battle Royale games. Treyarch is adding zombies now. These are intended to create more chaos in the large battles on the map. Players will need to adjust their tactics and always prepare for unforeseen situations.
Zombies are there to make your life difficult. You can also use them to lure enemies into a trap. This should make the gameplay of Blackout more varied.
How are fans reacting to the PvE component? As discussions on Reddit show, fans are somewhat divided about this announcement.
Most find it good that zombies provide variety and chaos. Thus, Call of Duty: Black Ops 4 Blackout does not play like every other Battle Royale shooter.
Some fear that this could negatively impact performance. Others hope that zombies can also be disabled to experience “traditional” Battle Royale gameplay.
The Call of Duty Black Ops 4 Blackout Beta will show how well this additional PvE component fits into the Battle Royale battles.
