How to fix game crashing at intro/mission 2 start

The problem is the DivX and the cinematic videos game has.
Even if you skip the intro via launch arguments, the game will start crashing anyway from mission 2 onwards due to cinematic briefing. Let's fix it then.

The solution is very simple - replacing DivxMediaLib.dll, and DivxDecoder.dll in game's directory with new ones download from the internet.

In case you need more specific instructions:

1. Right-click on the game in the Steam Library and click "Properties"
   
2. In the properties window, go to "Installed Files" tab and click "Browse..." to open directory with the game
   
3. Delete the DivxMediaLib.dll, and DivxDecoder.dll files
   
4. Download the https://www.dll-files.com/divxmedialib.dll.html and https://www.dll-files.com/divxdecoder.dll.html from the internet
   
5. Extract the DivxMediaLib.dll, and DivxDecoder.dll files from the archives and copy then into the game's directory, essentially replacing the previous ones
   
6. Boot up and enjoy

In case you ever have to reinstall the game or "check integrity of game's cache", you will have to repeat this process.

I tried to make the guide as simple as possible, if something is unclear ask me via comment.
