While I can't fully corroborate this (yet), it was previously shared on Twitter (X, via Insider Gaming) that Call of Duty 2024 will feature returning maps from the Black Ops franchise, including Grind and WMD. Game file leaks also point to round-based zombie modes returning. Insider Gaming has been reporting on this for a while, sharing the Cerberus codename which I can now corroborate. We're still locking down details on the format zombies will take for Call of Duty: Black Ops "6," to see if we can corroborate some of those previous reports.
