UNNOFFICIAL PORT Apocalyptic Fortress

by SymWizard07

Unnoficial Port of Apocalyptic Fortress overhauls the Nether fortress, adding a more complex interior and exterior, expanded exploration, and interactive decorative blocks for NeoForge 1.21.1.

What it does

The port keeps the Nether fortress overhaul of the original mod, which focuses on gameplay and the visual side of the structure. Most decorative blocks in the fortress interact with gameplay, the interior and exterior are more complex, and the exploration area is larger. Some wither skeletons spawn holding a bow instead of a stone sword, and a few features, such as the fortress beacon, noticeably change the difficulty.

The beacon is locked in some fortresses and needs a blaze key from a fortress chest to open. Once active, it grants resistance to fortress mobs and removes fire resistance from players, with a default range of 32 blocks. Right-clicking with a lava bucket raises the effective range by one block up to 64, a water bucket lowers it to a minimum of one, and either change uses the liquid. Right-clicking disables its effects.

The mod is open source under the MIT License and requires GeckoLib for NeoForge 1.21.1, version 4.8.4 or later. Better Combat is optional and affects how smashable pots are hit. It is published only for NeoForge 1.21.1, and both the server and every player need it. This port is maintained so the mod runs on newer NeoForge builds. Credit for the design, content and art belongs to the original developer.

Key features

  1. Complex fortress structure

    The Nether fortress interior and exterior are rebuilt with more detail and a larger explorable area.

  2. Interactive decorative blocks

    Most decorative blocks in the fortress have gameplay functions rather than serving only as decoration.

  3. Locked dungeon chests and blaze keys

    Some fortress chests hold blaze keys that open dungeon chests with valuable fortress items.

  4. Fortress beacon

    A beacon that grants resistance to hostile mobs and removes players' fire resistance, with range set by liquid buckets.
