I'm doing the guide for the first time, because couldn't find it on steam.*(

Step 1


https://github.com/atom0s/Steamless/releases

U need to download Steamless,just need first file (Steamless.v3.1.0.2.-.by.atom0s.zip)
Unpack the game exe to avoid errors
Then unpack the archive with software like 7zip or PeaZip.
Launch the tool through its .exe
For the file to unpack,for me select D:\SteamLibrary\steamapps\common\Arise\Arise\Binaries\Win64/Arise-Win64-Shipping found in the main game folder.
Click on Unpack File.
If succeeded, remove or back up the original game exe, then rename the .unpacked file to PlanetAlpha-Win64-Shipping.exe
Done! The game executable is ready for modification.

Step 2

Just choose the display resolution you need in this site and download it

Then just point the path to the patched version in the steam root folder and it all done.Unfortunately, without the first step, I got an error in the game.That's all, hope it helps someone.
