About this event
Play on any selected BO1, BO2 or World at War server during the one-hour window. Your best eligible session-kill total is ranked automatically. Select all games or individual servers that should participate.
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 session kills wins; round, fewest retries and 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.
