Project README



A very experimental modification platform for Call of Duty®: Black Ops 4 run by community, aiming at improving both functionality and performance of original game.


As of May11, 2023 we merged 'demonware' branch into 'master'. it includes a built-in demonware server emulator which allows player to start game without connection to official online servers.


you should have publisher files required for playing online under LPC folder of your game directory. if its not the case then start original game through battlenet launcher once to get those downloaded.

1- clone repository with its sub-modules and use generate.bat to make visual studio solution then compile project and copy d3d11.dll into your bo4 folder.

2- start BlackOps4.exe

in case you wanted to revert back to original battlenet servers just delete d3d11.dll. you can put it back later whenever you want to re-install client.


github issues section is only for reporting programmatically errors of client. please dont use it for requesting features or seeking help with personal issues such as faulty game data or similar problems. use battlenet's scan and repair feature to fix those problems.
