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](https://modrinth.com/datapack/ocean-breaths) to add underwater breathing mecanisms - crossover with [Blue Depths](https://modrinth.com/datapack/blue-depths-ocean-ecosystem-expansion-datapack) 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~~ ![Dive into the abyss](https://cdn.modrinth.com/data/69JB7rtT/images/206f9d9fc594dbfec39a551a55d2adf8fe9b6f9b.png) ## Datapack's Options In game, use: ```/function fkdbos:options/get```
