DOOM I + II - Legacy Of Rust - Forfeited Salvation

Legacy of Rust is an ID24-compatible expansion, with two new episodes The Vulcan Abyss and Counterfeit Eden. It features six new enemies, two new weapons, and many new textures all based on unused and cut content.
It was released on August 8, 2024, being spearheaded by Xaser Acheron, who also provided an all-new soundtrack. It was released alongside the Doom and Doom II re-release titled Doom + Doom II, which uses the KEX Engine, replacing the official Unity port.
"Created in collaboration by id Software, Nightdive Studios, and MachineGames, Legacy of Rust is the newest episode for DOOM, and the first official episode since DOOM II to feature new demons and weapons. This 16-map Episode is broken up into two 8 map sections: The Vulcan Abyss and Counterfeit Eden."
""Vassago's Rest", the ancient inscriptions called it. With the meaning of the name lost to time, it wasn't long before the interlopers began calling the land by another: "New Eden". Just like the Garden of old, mankind's exile from this newly settled realm was swift and brutal.
This remote region of Hell, overflowing in (un-)natural resources as it were, was almost entirely devoid of demonic presence. The Union Aerospace Corporation, never one to shy away from hubris and excess, learned the hard way that even the demons feared something greater, something deeper. When the Ones Beneath awoke, the UAC's crown jewel was swallowed in a cascade of blood and fire.
Three hours -- all it took to reduce New Eden to a sea of molten glass.
Three minutes -- all it took before the UAC's top brass played their ace.
Three seconds -- all it took for you to weigh the risks before accepting the job.
Your orders are clear: reclaim the lost base and preserve the UAC's Legacy.
Or die trying."
