Call of Duty: Black Ops 4 leaderboards

A leaderboard is the ranking of a single spawn room. Every Call of Duty Zombies map has its own: the players who held it, the round they reached, from solo to four players, each backed by its video. Some rooms are played several ways — the two sides of Verrückt, its Double Side and Reversed variants, Buried, Town and Farm with their unofficial rules — and each way has its own tab on the map's page.

Ranked boards carry a difficulty coefficient out of ten, which is what makes a round on one map comparable to a round on another. There is no entry round: a run is listed however far it went, from the world record down to the first room cleared.

The same map can appear twice. Nacht der Untoten on Black Ops and its Black Ops III remaster are the same four walls, but not the same game: movement, weapons and pace all differ, so the runs are not comparable and the boards are separate.

Pick a game, pick a room, and read it from the world record down to the last run listed — or start from the hardest First Rooms, where every coefficient is laid side by side.
