Plutonium BO1 is a community-developed client/server framework that revives Call of Duty: Black Ops 1 multiplayer with modern matchmaking, custom mods, and dedicated server support — independent of the long-defunct GameSpy and Demonware backends. Run private or public lobbies with any gametype, full mod compatibility, and zombie modes.
The servers are booted, select your plan and become our latest satisfied client.
