Plutonium Nucleus Handlers (BO2 Zombies)

Nucleus Co-op handlers that launch Call of Duty: Black Ops II Zombies through Plutonium instead of the Steam client.

Why Plutonium? Controllers get native aim assist. Steam BO2 on Nucleus typically does not.

Folder	Mode	Status
LAN/	Offline LAN (-lan)	Working — see LAN README
WAN/	Online / Plutonium network	Impossible because of anti-cheat

Requirements

• Nucleus Co-op
• Steam Black Ops II installed (game files; Nucleus adds the game via Steam t6zm.exe)
• Plutonium installed and run at least once (so %LOCALAPPDATA%\Plutonium exists and game files are downloaded)

You do not need to put this whole repo into Nucleus. Install the handler package from the mode folder you want (LAN or later WAN).

Quick start (LAN)

1. Open LAN/ and follow the full play guide in LAN/README.md.
2. If you already have a BO2 Zombies handler installed, remove it first — Nucleus will not overwrite it properly when you import the .nc.
3. Install Call of Duty Black Ops 2 Plutonium Zombies.nc into Nucleus. When the “Select which game to add” popup appears, choose Call of Duty Black Ops 2 Plutonium Zombies (not the plain Zombies handler).
4. Add the game by browsing to Steam BO2’s t6zm.exe.
5. Short version: wait for instance 1 resize → Online → Custom Games → set min players → Start → OK Nucleus prompt → each joiner: connect localhost:1111 after resize → lock inputs with END.

launches with -lan. Instances talk over a local port (host listens on 1111). One Plutonium install / one logged-in account on the PC is enough.
