Here is a Starbound mod that allows you to unlock all of Starbound's achievements by simply killing any creature in the game. Install the mod and then kill something to reap in the achievements.
Use Starbound's asset packer in the command line to pack the entire folder of code into a *.pak file and place that file in Starbound\mods.
cd "C:\Program Files (x86)\Steam\steamapps\common\Starbound\win32"
asset_packer.exe %PathToMod% ..\mods\AchievementUnlocker.pak
Don't forget to replace %PathToMod% with the complete path to your Achievement Unlocker folder.
You can subscribe to the mod on steam or move the latest GitHub release to your Starbound\mods folder to use the latest stable release.
You may have noticed that I have not updated the mod in a long while. I never needed to! The old mod still works as of 7/6/2022 and it looks like that's never going to change.
