About this Mod

Survive a post-apocalyptic world submerged by water in a nearly vanilla experience.

BETA: bug may be found. Please, send feedback on PMC/discord/youtube/patreon/any networks. Please, also include your feeling about it (emotion, difficulty, ideas).

Features

  • ocean only worldgen
  • deeper oceans: from shallows at 20 meters up to the 300+ meters of the abyss.
  • very very rare emerged island
  • custom player buoyancy depending on the current depth
  • player's default O²: 30 seconds
  • recipes and craft to help the begining of your journey
  • few structures: base spawn, floating wood, under water pit
  • achievements/advancements as progression (follow the guide only if you want)
  • randomized water creature sizes (+/- 50%), 1% chance to be "megalodon" (+200%)
  • crossover with Ocean Breaths to add underwater breathing mecanisms
  • crossover with Blue Depths to add fishes, jellyfishes and sharks in oceans

Planned (futur update)

  • depth pressure damage: craft diving armor to be protected and dive deeper. The goal is to slow down deeper exploration
  • break doors in water (try to remove this bug use)
  • more structure to explore
  • bigger pool of spawns (floating start structures)
  • adjust difficulty (depending on the feedback)
  • more achievements about challenges
  • crossover with Blue Depths
