Rifted Valkyrium
Rifted Valkyrium is a Forge fork of Valkyrien Skies 1 that aims to fix lingering issues in the original and continue its maintenance.
What it does
The fork is an unofficial continuation of Valkyrien Skies 1 that restores the mod after work on the original slowed. It bundles VS Core, so the core, VS Control and VS World come in one install. The developers describe it as a drop-in replacement for Unvalkyried Heavens and VS1, keeping registry names so existing worlds keep working. Rudders that were broken in earlier builds are fixed, and parts of the code have been cleaned up and separated into VS Core and VS Control.
Ships gain buoyancy tanks meant for sea travel, and physics runs on the Nvidia PhysX backend. Boat oaring from Create Aeronautics has been backported. Installation requires the Cleanroom modloader, since the fork does not run on other loaders. The mod is client and server, so the server and every player need it. Files are published for 1.12.2 only, with 2.1.0 as the latest Forge file, released on 2026-10-03. The code is open source under the Apache License 2.0.

Who it’s for: Players and server owners who want Valkyrien Skies 1 ships on Forge for 1.12.2, with the Cleanroom modloader installed.
How it compares
Dragon Mounts Legacy Continued is also a Forge mod for 1.12.2, released under a custom license and not open source, with the same client and server environment. Valkyrien Skies: Tournament Reforged runs on Forge for 1.20.1 under the Apache License 2.0, so it targets a newer game version than this fork.
