Season six of Call of Duty: Warzone will be arriving soon, and a horde of zombies may come with it.

A reddit user shared some voice recordings from the upcoming Warzone season that contain explicit mentions of zombies.

The audio snippets specifically mention zombies in the context of a battle royale, players turning into zombies, and surviving attacks from zombie swarms.

According to the recordings, zombie royale will be a survival mode much like the general Warzone battle royale mode. The big change though is that players will be fighting against both zombies and regular players.

The mode will likely turn defeated players into zombies without a buy back option to return as humans (although they may still have another chance to become human again during a match).

Zombies will not only be immune to the ever-encroaching gas but actually stronger within it. That makes getting stuck in the gas way scarier.

Elsewhere in the recordings, a helicopter is mentioned, suggesting that the way to win is to reach the chopper and get evacuated. If the helicopter goes down, however, you'll have to fight your way through a zombie infestation.

Zombies are also coming to Call of Duty: Black Ops Cold War, but their role in the game has yet to be determined.
