What is PlutoT6?

[Xerxes]

PlutoT6, also known as Plutonium T6, is an alternative Client for for Black Ops 2 which allows mods and private ranked dedicated server hosting. It is the only BO2 client that has a working online mode and connect command. It not only features dedicated servers for MP but also for ZM which allowes up to 8 players on any map. While custom maps are still a thing of the future for T6, Plutonium T6 does have a new mod support for T6 which already does allow to port assets between maps and game modes. Next to their upcoming mod support one of the most important features of Plutonium T6 is their anticheat. But also many bug fixes are included, be it bugs as old as the game or ones caused by new hardware. For a full changelog of all changes see Plutonium’s changelog.
