Entropy : Zero 2

Hello @bigjoe54321, this game has a Linux native variant. If a Proton log isn't being generated when you expected it, that implies that you're using that version of the game and Proton isn't involved at all. Issues with Linux native games should be reported directly to the game's dev(s). You can check what Steam's configured to use by selecting the game, then pressing the ⓘ button on the right.
