[Linux + Proton] Bypass 2K Launcher

You probably have already seen the other popular 2K Bypass Guide made by: BezaoBuilder.

But that guide's Linux bypass only worked for Linux Native Civ6, and I have problems while running native Civ6 so I have to resort to using Proton. So with that I decided to share this small fix for people in the same boat as me!

Put this in Launch Options:

eval $( echo "%command%" | sed "s/2KLauncher\/LauncherPatcher.exe'.*/Base\/Binaries\/Win64Steam\/CivilizationVI'/" )

For DX12, just put CivilizationVI_DX12 instead of being plain CivilizationVI like in the code.
Found in ProtonDB[www.protondb.com]

Edit 1: Use "Proton Experimental" instead of the 6.3-2 Proton, it runs perfectly offline/online with all DLCs and with dozens of 3rd Party mods.

This based command still works.

Bikun: I'm pretty sure you need to run the game with the launcher, sign in to 2K, and then you can use the bypass script and keep Ceaser.

I cannot access Julius Ceaser, But I was able to bypass the launcher and the 2K account option on the lower right corner is grayed out (offline).
Is there anyway I can get Ceaser?

What's with the issue and solution crap ? The original post works just fine.

If anyone is running into some issue, for me this did not work with the latest versions of proton (9.0 and experimental)

I reverted to proton 6.3-8 and then it did work for me (I did not check any other versions)

Thanks, I didn't think such a simple solution could work, but it's running perfectly fine.

Linux native version: No mod support, bad performance, no 2k launcher
Windows native: 2k launcher but everything works fine
why is firaxis like this?

You're the best been trying to get this to work for 2 days

Thanks very much.
I am a semi-shut in, solitary old geezer. The high point of my week is playing online with my adult son who lives 3000 miles away, so you did me a BIG favor.

Thanks a lot, this works great. Working with Proton-GE.

If anyone has issues similar to what Dimike96 is describing (when this guide's launch option is NOT applied), delete the "T2GP Launcher" folders within the game's Wine prefix. E.g.:

$ rm -rf ~/.local/share/Steam/steamapps/compatdata/289070/pfx/drive_c/users/steamuser/AppData/Local/T2GP\ Launcher
$ rm -rf ~/.local/share/Steam/steamapps/compatdata/289070/pfx/drive_c/users/steamuser/AppData/Roaming/T2GP\ Launcher

You have to do this every time before you launch. Now you see why I sought a workaround.
