Hey zerfines, if you feel like giving this a try here's how I did it. This game has been updating like crazy, last time I tweaked the save file was 2 years ago so I don't know if it can still be changed, but the file looks the same and as long as you backup your saved game file it can't hurt. So here is the path to my saved game on my PC, "D:\games\steamapps\common\Empyrion - Galactic Survival\Saves\Games" . Open the folder to the saved game you want to tweak, "D:\games\steamapps\common\Empyrion - Galactic Survival\Saves\Games\1-11-18\Templates\NewDesert_V2" and locate the file named "playfield.yaml" . When you open the file(I use notepad) find "Creatures" these are the roaming creatures for that Planet. I've changed the amount of badguys, added badguys in other Biomes, and changed when they spawned(night and/or day). I've also added more Drones, and more resource deposits. If you do decide to try this and the game CTD just put the original file back in and your good to go. Good Luck!
