Koncord, Nice work, thank you!

Thank you for sharing this information.

Evil, thanks for mod! :)

In detail:
1) Make a backup for main config file:
...Steam\steamapps\common\POSTAL2Complete\System\Postal2.ini
2) Copy linux config from:
...Steam\steamapps\common\POSTAL2Complete\WorkshopContent\737631813\Postal2CoOp_Linux.ini or suggested one from the first message.
Paste it to: ...Steam\steamapps\common\POSTAL2Complete\System and rename into Postal2.ini
3) Launch game via steam/shortcut
P.S.To launch the regular Postal2 again, you need to delete the coop config and replace it with backup one.

I get this error when i launch the game with these settings:
An error has occurred. If you continually get the same error, try loading a different save file, submit a bug report, and/or check the Support Forums for assistance.

what if i don't have a workshop file? ( but the mod appears as a game mode when i start a new game )

it doesnt work for me, it just boots into regular postal 2

Seems like something has changed in years.

is there another way to launch the mod? Do you mind taking a look for me? I really like postal 2 and want to play it so badly. proton ♥♥♥♥♥ itself when running postal 2, so thats not an option

Will try ;)

turns out at least for debian, the config files are stored in ~/.lgp/postal2/System instead of the system directory for the game

but now as soon as i jaunch the game, it disables nicks coop in the properties of the game? my assumption is that the workshop files are also downloaded to a different place, so ill try changing the config accordingly

yeah its downloaded to ~/.lgp/postal2/WorkshopContent
do you mind helping me edit the ini to fix it respectivley?

im now getting an error when i try host a game. the log is as follows:

and when i start the game, it it unticks itself under properties > workshop? i think its still installed though? ive also tried all the older versions of postal 2 under the beta.
