Plutonium

NuggetPSV Why would you need plutonium for singleplayer campaign? You can just launch mw2 on steam and play the campaign. It's not like your playing multiplayer.

PSN Nice profile you have there.

Try unpin, uninstalling your third party antivirus, could be your dns, firewall, etc.

Why does your thing have chinese characters? Is your game files from steam?

bro got syntax error. ;

Resxt lol got it

Seqa159 Your path should be similar to this:
C:\Program Files (x86)\Steam\steamapps\common\Call of Duty Black Ops II

If your game files are not from steam then can't help you any further.
After all you opening this old topic, which is no longer supported.

PinapXpress420 No campaign isn't supported and will never be. After all plutonium is a client to patch the security risk of the game, which is mainly zombies and multiplayer. Just launch the game through steam and play the game with a mouse and keyboard. If not you can just play normally with xbox button prompts after all it's no big of an issue. If you try to play it through plutonium, you'll just get an error issue later in the playthrough.

Black Lament Plutonium is a free project, so they don't really have to do your bidding. Almost most of the bans are done by the anticheat. People not reading the anticheat or not researching thoroughly. The reason why Steam Decks are getting banned is because they have similar hardware/hwid. Someone decided to cheat on the steam deck, which ruined the experience for others. I don't think they'll be lifting it anytime soon as it's a security/cheater risk. So, technically this isn't the plutonium team fault but the community or that person fault who decided to cheat on a steam deck.
In short, steam decks works fine but isn't technically supported, however someone decided to cheat and ruin the experience for other steam deck players.

MadScribe What antivirus you got cause you don't need it. Uninstall it as Windows Defender is all you need to protect your device. No need for mcafee, bitdefender, etc. Even if its disable some features are still working in the background.

Piracy is no longer supported.

That because someone tried to cheat on steam deck. Steam Decks uses the same HWID which means if one device gets banned all those with the same HWID also gets banned. It isn't really supported much either.
