There may be no traditional single player story campaign in Call of Duty: Black Ops 4. Polygon, Kotaku, and CharlieIntel cite their own sources for these reports stating that publisher Activision halted development on the usual set piece extravaganza of celebrity likenesses and explosions in favor of more multiplayer modes, with rumors pointing to some version of Battle Royale filling out the package. These sources named Raven Software as the primary developer of this Call of Duty’s Battle Royale gameplay. Raven is the studio behind Call of Duty Online available in China which does offer a Battle Royale mode.
Earlier rumors had stated that like Infinite Warfare, this next Call of Duty might offer an HD remake of an earlier game in the franchise as an incentive – in this case, Call of Duty: Modern Warfare 2. That rumor’s detail, that the Modern Warfare 2 remaster would not have a multiplayer component, now makes a lot of sense in light of this new information.
