Restore mhyprotect.Sys from your Anti-Virus and add it to exclusion list

Error (3, 1020, 143008) Test Mode Activated

InControlNative.dll caused an Access Violation
You can choose one of these solutions: Run game as administrator Delete InControlNative.dll in <path-to-game>\Plugins Notes Delete InControlNative.dll will cause game to not detect controllers

BSOD or crashes caused by UniFairy.sys

Make sure that: Installed official OEM drivers. There is no applications or anything else that try to hook into the game. UniFairy.sys is not in the game folder (may cause conflict with the Anti-Cheat itself) Have enough RAM for the game (seems like the Anti-Cheat doesn't like being disk cached or getting compressed) Notes RAM Compression feature is only available on Windows 10 and only happens when the machine ran out of RAM.

Dualshock 4 issues

Not working properly

Make sure that: Your controller version is v2 Use new Bluetooth version (recommend using Bluetooth 4.0 adapter or higher) If still not working, add BH3.exe to Steam and run game on Steam with controller detected on Steam If still not working on 3, you can use controller wrappers like DS4Windows or XOutput If still not working on 4, you can try using wired mode Check if your controller even working properly by using online controller test

Other issues

Notes If network is unstable, the Start button will becomes Update button and players will see the above text although there is no new update.

CG doesn't have subtitles

Extract any .srt from the .zip files manually in <path-to-game>\BH3_Data\StreamingAssets\Video to the same folder. Note BH3 in BH3_Data may have different name depending on the server. In-game, you can download all CGs(and also subtitles) of the game by pressing the Download button on the top left in Phone\Collection\Cutscene, letting you extract all subtitles at once without revisiting the folder frequently.

Go to Control Panel\Region\Formats and change the Format to English(US) or English(UK) Note This can also fix other issues, like the giant models in in-game events like Cybernet.
