"As Gun Media closed the game backend we made a Online Fix patch to keep the game playable online.

Please note that this online fix is not supported/endorsed by Gun Media and is unofficial.

The installation is very simple.

0) Download lastest version of the patch *:
-> archive(dot)org/details/f13-onlinefix
-> replace (dot) with .
1) Make sure F13 Game is up to date with Steam and the game is closed
2) Extract F13Game folder to your steam content folder
(by default : C:\Program Files (x86)\Steam\steamapps\common)
3) Click "Yes" to replace existing files
(make sure it asked to replace files, if not you putted it to wrong place !)
4) DONE ! Enjoy again F13 online with your friends.

* click only on "RAR download", if you don't have tool to extract the archive, i suggest the free one 7zip. Files are safe and got analysed by lot of people around here.
However, because of the missing digital signatures from files, Windows Defender (only on Windows 11) can treat it as a false positive. Any other antivirus will confirm that files are 100% safe. If you have any doubts, feel free to test the files on any online AV."
