High-Round Sprint — all selected Zombies maps

Players have to reach the highest round possible on all selected Zombies maps. The timer begins with the eligible server session and the final completed round is recorded when the run ends. Normal in-map strategies are allowed unless the published event adds a restriction. Player format: Solo and co-op are allowed. Each linked player has an individual leaderboard row; co-op players share the reached round and keep their own kills. Eligibility: Only linked EN accounts are scored; spectators and unlinked players are excluded. Winner: Highest verified round wins; kills, then fewest retries, then fastest valid run break ties. Attempts: A new eligible server session is one attempt. The first is free; later sessions are retries. Where to play: Only the selected World at War, Black Ops, Black Ops II servers and maps count.
