Black Ops Cold War and Warzone patch notes: Bug fixes, attack helicopters, Zed 398 error and more

The first season of Black Ops Cold War with Warzone integration brought a tonne of content to the Battle Royale, and the latest FPS from Treyarch. However, it also brought with it some serious issues, such as the game-breaking invisibility exploit/glitch, the Zed 398 Swift Clover error and some additional bugs. 

On 17th December, Treyarch released a new update, and shared the Black Ops Cold War and Warzone patch notes, focusing mostly on fixing issues in both titles. 

Warzone & Cold War: Biggest fixes explained

Since the release of Black Ops Cold War and Warzone Season One, PC gamers have been experiencing the Zed 398 Swift Clover error, which prevented them from loading into Season One maps. With the latest patch, this issue has now been resolved.

Shortly after the release of Season One, we reported about a game-breaking exploit turning players invisible. This involved the new Attack Helicopters, which have been temporarily removed from both Verdansk and Rebirth Island.
