About this project
What does Undiscovered Abyss: Deep Waters add?
Deep Waters
Best way to play: the Undiscovered Abyss modpack. It installs as its own CurseForge profile with Deep Waters already set up alongside about 190 mods, a quest book, the resource pack and shaders. Click Install on the modpack and CurseForge does the rest.
The core mod of the Undiscovered Abyss modpack. It started as a fishing overhaul and grew into a whole adventure: explore, fish, fight.
Fish and sea life
- 473 species of fish and sea creatures, each with its own model and animation: fish, sharks, eels, rays, squid, octopus, jellyfish, crabs and lobsters, turtles, dolphins, whales and more.
- Every place has its own waters. The Nether and the Eclipse have lava swimmers that cruise and leap from the lava.
- A fishing journal records every catch, with rarities from common to mythic and rare mutations.
- Rods with perks, held in 3D, with a real casting line, bites and a struggle.
Places to go
- Saltmere Harbour: a fishing town with a tackle shop that buys your catch.
- Sea dimensions: the Abyss, the Frozen Sea, the Sunken Kingdom, the Toxic Swamp and Leviathan's Maw.
- Four portal realms, each opened by its own ritual: the Overgrowth, the Stormreach, the Crystal Hollow and the Eclipse.
- New villages, buildings and points of interest across the world.
- A submarine for the deep.
Fights
- Bosses with their own arenas and attacks: the Infernal, Frost and Tempest titans, the Drowned King, the Eclipse Tyrant, the Gravelord, the Bog Matriarch, the Prism Queen, the Rootmother, the Abyssal Kraken and the Leviathan.
- Monsters that use their weapons (thrusts, slashes, reaps), plus wildlife you can hunt, tame and ride.
- The Armory: weapons, tools and armour in eight ore tiers, smithed up realm by realm, and a combat harpoon gun.
- Boss trophy heads for your walls.
Also
- A quest book that guides you through everything.
- A Deep Waters resource pack and shaders (both in the modpack).
Requirements
- Minecraft 1.21.1, NeoForge 21.1.219 or newer.
- Works on its own, but it's built for the Undiscovered Abyss modpack, which adds its quest chapters for the other mods.
Made by D4 Studios.
