GhostRider0125 Not sure, you're gonna have to ask the plutonium team yourself.

NicoValentino_ actually if you've seen other people ban appeals on the forums or discord. I have seen none got approved before.

NicoValentino_ yeah, "you believe that what you're saying is true", but "how do I know what you're saying is the truth?"

Btw no matter how much you say, the admins don't do unbans so arguing isn't going to do anything for you.

NicoValentino_ I do not know what you did, only you know what you did. I'm pretty sure Admins have logs but they aren't the type to give it out. How can I guarantee that what you're saying is the truth or not?

NicoValentino_ It doesn't matter, as long as it messes with the game code. You were already warned the first time and didn't heed that warning. It was your responsibility to not do what you did the first time.

NicoValentino_ I'm pretty sure doesn't have to be a cheat to be banned. It can be any external tools.

Where did you get your game files?

L0ST Huh what do you mean on steam?

You would have to buy the DLC also.

then it is probably your internet provider. Have you tried a VPN or a Hotspot?

Alien_503 If you have 20 days then that means you created alt accounts trying to bypass your ban. All it ever did was add more days to your ban. Nothing you can do but except to wait it out. If you do it again and caught again by the anticheat then it is a permanent ban. If you're trying to load a mod menu such as a gsc, script, or mod. There is already a supported way to load them into the game without getting banned.

Loading Mods into Plutonium

You mean ban?
You must have violated the anticheat.

How long is it? If its 7 days then don't do whatever you did.

You buy the DLC with it.

You buy the game on steam. That the only answer you'll get unfortunately, as plutonium no longer supports it.

Not anymore since the sm2 and xlab incident. Plutonium is a client not the game itself.

What do you mean survival mode solo offline on Black Ops 2? There is LAN mode but that isn't really offline.

You can try this.
Offline Plutonium Launcher

Something that probably has to do with your firewall, antivirus, internet provider, or DNS.

You violated the anticheat system.
https://plutonium.pw/docs/anticheat/
If you create another account, you'll further your ban. If you do it again, you'll be permanently banned.
The anticheat system is always on even if its a solo match or custom lobbies. There is already another way to install scripts, GSC, or mods in the documents.
If you want to play campaign launch the game on steam without plutonium or else you'll get an error.

If your game files are pirated then I won't be able to help you any further.

Where did you get your game files?

Morty96 Unpin plutonium from your taskbar. Open the location of plutonium inside your file explorer and run the plutonium.exe. It should update.
