This particular guide is focused around the dev menu and commands I've found.

Enabling the Dev menu is relatively easy. I *strongly* recommend using Notepad++.

Open the following file in Notepad++:
X:\Steam\steamapps\common\EmpireOfSin\EmpireOfSin_Data\StreamingAssets\Settings\DefaultPlatformSettings_PC.json





In this file you will find a setting called "developerMode" and set it to "true" DO NOT CAPITALIZE






You should see "[Dev] QA Perf Test" on start menu if it worked.
You can use (`) to open the console.
You can also press ALT + 1 to open a GUI menu.
You can also access the GUI menu via the pause screen.
