I’ve played Subnautica so much that it’s no longer a challenge, even on hardcore. I installed this mod (Deathrun Remade) to increase the difficulty and had the most fun I’ve had in a while
Deathrun Remade
Turns Subnautica into a difficult roguelike experience that challenges you to use everything you know about the game to survive the decompression sickness, Aurora explosion, abundant radiation, bloodt
The hardcore mode on that is really fun…most of the time. Watch out for the stinging tentacles, they will mess your whole run up, and NEVER accidentally press the button to exit the sea moth when it’s at full speed. That mfkr will turn you into a smoothie lol
