UPDATE: ESRB has now removed the listing. It appears that it has gone live earlier than it should have.
The ESRB Rating Board in the US has officially put up a listing rating Call of Duty: Black Ops 3 Zombies Chronicles for PlayStation 4, Xbox One, and PC M for MATURE.
The rating appears to have gone live today. ESRB usually only rates games that are getting separate releases, meaning it appears Zombies Chronicles will be available separately at retailers too, as well as digitally. ESRB ratings go live when a new product is close to launch, meaning Zombies Chronicles should be releasing at some point in the near future.
The rating summary does not officially reveal what’s included with Zombies Chronicles.
Previously, a leak from a retailer in Mexico stated that Zombies Chronicles for Call of Duty: Black Ops 3 will include 8 remastered Treyarch Zombies map for Call of Duty: Black Ops 3.
Activision has yet to officially announce any details about this. Stay tuned.
