Orbital Railgun Unofficial Port
Orbital Railgun Unofficial Port brings an orbital strike weapon to Fabric 1.21.1, letting players call down a railgun blast on enemies.
What it does
The port ports the Orbital Railgun Mod for Fabric on Minecraft 1.21.1, carrying over the orbital strike that destroys enemies. The author describes the release as an unofficial port of the 1.21 version and adds shader-driven visual effects with fast-moving lights and chromatic aberration, so viewers sensitive to flashing light should take the photosensitivity warning seriously.
Geckolib is required and must be installed alongside the mod, since the effects depend on it. Installation covers the server and each player's game. The code is open source under the MIT License, and the public source repository is available for inspection.
The latest Fabric build is 1.1.2, first published on 2026-01-24 and last updated on 2026-01-30. Among the 1538 Technology mods with Fabric files for 1.21.1, this one sits in the Technology category with equipment and game mechanics as secondary tags.
