Just like all previous updates split between Black Ops Cold War and Warzone, there are two different release times worth being made aware of based on the game you’re playing.

  • Black Ops Cold War — For all updates to multiplayer and Zombies, the Season 4 Reloaded update, likely to be version number 1.20 on PS4, is expected to go live July 14 at 12 a.m. Eastern. This initial deployment will likely just include balance changes, with major changes going live closer to July 15. The update size is about 15-20 GB depending on platform.
  • Warzone — If you’re interested in Warzone updates, those will go live July 15 at 12 a.m. Eastern. The update will be about 10 GB depending on the platform.

One thing to note for those particularly interested in Zombies, however, is that the Easter egg quest for the Mauer Der Toten map probably won’t be turned on immediately after the update goes live or at midnight on July 15. Instead, we expect the hunt to begin July 15 around 1 p.m. Eastern. We’ll update this section as we learn more.
