List of any relevant gameplay differences that we know of. I've based this list on the Steam version, but other versions should have a similar list as well.

Official patch notes are available here, though they aren't always complete: https://support.505games.com/support/solutions/folders/150000539399

• FPS enemy encounter issue fixed
• Lam recruitment bug fixed

15 May 2024:

• Cookoff bug is fixed, where all rounds used to be considered as appetiser rounds
• Can’t prematurely access Eldroad anymore after finishing Impershiarc storyline

4 June 2024:

• “Development Build” version with debugger was released, and got patched out in the same day
