Beyond the Ocean
by Bogerplayer
Beyond the Ocean adds two ocean-themed dimensions to NeoForge 1.21.1, reached through portals that a player activates after finding certain structures.
What it does
The mod is a story-driven addition inspired by Subnautica. Each of its two dimensions is themed around the ocean and is entered by activating a portal block that appears in found structures. Players are meant to explore the planets over a long stretch of play, and the content adds many hours to the endgame. Nothing is required from the player beyond reaching the portals.
The additions cover creatures, combat and technology. Dozens of new fish are included, along with leviathan-class creatures and several bosses. Armor sets, weapons, Terraria-style pets, diving gear and vehicles appear alongside more than a hundred new building blocks, unique charms and machine blocks that run on Redstone Flux. The mod needs no other mods for its core content.
Beyond the Ocean runs on the client and on the server, so both sides need it installed. It is published for NeoForge only, with 1.1.0 as the latest file for 1.21.1, released under All rights reserved and not open source. The first file appeared on 2026-04-29 and the last update was on 2026-06-21.
