Game runs natively but it relies on OpenSSL 1.1 which is removed from most distros like Ubuntu/Debian, while some distros offer a compatibility package to install them.
If you can install the compatibility package do so, otherwise download the older debian/ubuntu package extract it somewhere and use launch options to override LD_LIBRARY_PATH so it can find those libraries (Alternatively you can copy the libraries in your /usr/lib however I advise against touching system files like that)
Launch option example (replace with path to extracted libssl1.1 package's lib folder):
env LD_LIBRARY_PATH="/home/ravener/Downloads/libssl1.1_1.1.1w-0+deb11u2_amd64/data/usr/lib/x86_64-linux-gnu" %command%

não funcionou de forma alguma, nem com proton experimental, nem com proton GE, NADA
incompativel.

Wouldnt start at all without forcing protcon experimental.

Proton experimental and plug and play. Rodou fácil

Linux version doesnt work so swich to proton experimental
The native Linux version does not want to start. Changing to Proton (I just went with the default, the curren experimental) the game starts and I was able to play through the first few minutes of the game.
