Plutonium

Why do you talk like that you motherfucker!
Your program is a piece of shit that ruined the game
Shame on you and your program
Repairing it costs only 15 GB
Go and fuck yourself

Problem in progress
The story mode was working fine. I downloaded the plutonium program to play the zombie mode and online
The situation has become incomprehensible! Now the online and zombie modes work fine, but when entering the story, this message appears
Steam must be running to play this game
Is there a solution to this problem ?
