Include player modification for surviving depths

Adds intensity to game and also makes good use of new player modification and adds a realistic aspect to game. Easy add also since game already does this with breathing capability reduction.

Agreed, I want water pressure to be a more immersive feature.

Also add possiblity only way to get it is by maybe scanning a dangerous levaithon. Maybe include not only scan but also maybe like collecting stalker tooth collecting DNA than taking it to modify yourself. Or another one is an upgrade from an extinct creature found only at an alien base inside you need to scan it. Make it look terrifying. Like thank goodness it isn’t still alive make it difficult to obtain like in triton than only way in without death is inside moon pool with new prawn suit because depth will otherwise kill you. This will of course be for a late game upgrades. Once having final upgrade remove crush death from player entirely and have PDA say levaithon capable of withstanding pressure of unknown levels warning extinct levaithon possess strength that possess a tough challenge to all known military technology.
