Skyrim Modder Uses Rust to Build Fully Playable Elden Ring Combat System

A new development in the The Elder Scrolls V: Skyrim modding community is moving away from generative AI trends to focus on high-performance manual engineering. A developer known as Funny-Bones has demonstrated a rebuilt player controller that brings the precise movement and combat logic of Elden Ring into Bethesda’s aging engine, bypasssing traditional scripting methods in favor of the Rust programming language.

The project, which was showcased on social media on October 6, features a Dovahkiin performing animations and combat maneuvers that mirror the weight and timing of FromSoftware’s titles. According to a post by the developer on X, the Skyrim mod adds real Elden Ring combat and is currently “fully playable,” though it has not yet been released to the public on platforms like Nexus Mods.

By moving away from standard scripting, the developer achieved higher performance for complex combat maneuvers.

The Technical Shift to Rust

The technical foundation of this mod represents a significant departure from standard Skyrim modifications. While most mods rely on Bethesda’s native Papyrus scripting or C++ via the Skyrim Script Extender (SKSE), Funny-Bones utilized Rust to build the core logic from scratch. This choice of a systems-level language is intended to provide better performance and portability.

Because the controller logic is written in Rust, it operates as a modular system rather than one hard-coded into Skyrim’s specific architecture. This approach suggests a theoretical future where such combat controllers could be ported to other engines or games, such as Fallout 4 or Starfield, without needing to rewrite the fundamental physics and timing logic from zero.

Human Craftsmanship vs. AI Simulation

The emergence of this functional mod comes at a time of increasing scrutiny toward “AI slop” within gaming circles. Recently, several viral videos claimed to show crossovers—such as Minecraft running inside Elden Ring—that were later identified as non-interactive generative AI videos rather than actual software. This Skyrim project stands as a counter-trend, prioritizing functional, interactive code over visual simulations that lack underlying gameplay mechanics.

While the demonstration shows a high level of polish in movement and combat responsiveness, the mod is expected to be uploaded “soon” as the developer finalizes the build. It remains unclear exactly which frameworks, such as Nemesis or Open Animation Replacer (OAR), will be required for the final installation, but the current showcase emphasizes a “built from scratch” philosophy that aims to bypass long-standing engine limitations.
