I suppose there's a way (me getting around to uploading it), I had an idea I wanted to do with it beforehand, but I'll upload it for now and update it later.
For other cases, download and rename the *uuid*.hpk to ModContent.hpk and make a new folder in %AppData%\Surviving Mars\Mods
(it doesn't matter what you call the folder). Edit: and move ModContent.hpk to the new folder.
