Abyssal Frontier

Players venture into naturally generated deep-ocean trenches, where surface buoys and salvage stations mark the way and readable pressure bands warn of rising danger. Survival depends on managing pressure, and a Depth Gauge with clear strain and critical warnings tracks it while the Riveted Bathysuit protects the diver. Loot caches on the trench floor reward those who reach them.

Pilots take the Copperfin, a submersible with lights, air storage and a reinforced hull built for dives down to 180 m. Marine life such as Lumen Rays and Brineback Isopods lives in the trenches, and feeding them is nonviolent. The Riftjaw Leviathan closes the path in three phases of pursuit, guided by sonar telegraphs and a boss bar, and awards a one-time reward on defeat. Guidance through a journal, advancements, accessibility settings and support for dedicated servers are included.

The mod requires Fabric API, and the Fabric Loader must be 0.19.3 or newer. It is a client and server mod, so both the client and a dedicated server install it. The code is not open source; the mod is released under All rights reserved, and public source code and an issue tracker are available.
