How Do You Fix The Warzone Bug 'Fatal Error: Unknown Function'? 

The Warzone Bug 'Fatal Error: Unknown Function' was caused by the update yesterday, Raven Software will come out with a fix in the next few hours or days, until then, follow these steps to get playing again. Note, this has been reported on all consoles and PC, so the same steps will apply to any user. 

  1. Check that the Warzone version you are playing is the most recent. We know this is what users always hear, but it works a lot of the time so do try it. 
  2. Restart your console or PC and try to relaunch the game. Again, this is cliché, but that's for a reason - these steps will often resolve the problem.
  3. Delete and re-download the entire game. Many users have been able to play since the update, so you might be able to install the latest version without error if you start from a clean install.
  4. Reddit user u/Quale51k suggested signing out of your Activision account and signing back in. One user on Xbox reported this working but others on PlayStation and PC said it did not resolve the problem. 

We really hope these fixes worked, nothing infuriates us as much as a bug in Warzone, especially just as the Weekend begins. If none of these steps worked for you don't worry, Raven should fix the Warzone bug 'Fatal Error: Unknown Function' with a patch in a matter of hours
