In just a few days, Call of Duty: Black Ops 4 will be unleashed to the masses, and while multiplayer and Blackout might be the ones getting the most attention, a lot of people are also picking up Black Ops 4 for  the Zombies mode that only Treyarch can deliver.

As part of the mode’s 10th year anniversary, Treyarch has something special in mind when it comes to Black Ops 4 Zombies Easter eggs. Posting a message on Reddit, Treyarch states, “Black Ops 4 Zombies Easter Eggs will be enabled worldwide in Voyage of Despair, IX, Blood of the Dead, and Classified at 10AM Pacific Time on Friday, October 12.”

Not only that, but the studio also mentions that it’s “cooking up something extra special” just for Zombies players. Could all this be connected to the hidden messages found in some of the Black Ops 4 trailers floating about?
