Looks like the official E3 Twitter account might have just outed Call of Duty: Black Ops 4's Zombies mode ahead of its official reveal.
"What’s lurking around the corner of @Treyarch’s next Call of Duty: Black Ops 4 Zombies experience?," the tweet reads. "Come hear the history of Call of Duty Zombies from the creators themselves at #E3Coliseum! Get your gamer pass today and be there. Purchase at http://e3expo.com #E32018."
Not much else about the potential mode is currently known. Treyarch will share more details about Black Ops 4's gameplay on May 17. Call of Duty: Black Ops 4 will be released for PlayStation 4, Xbox One, and PC worldwide on October 12.
