## Where it stands

Evil Engine finds Satisfactory on its own and reads its two big Unreal archives where they sit, without unpacking anything: 13,576 files in one and 34,997 in the other, laid over the install. Nearly all of it is compressed with Oodle, which the game ships no way to decode, so Evil Engine has its own decoder, written from a description of the format. Every one of the 59,158 chunks in the larger archive decodes and matches its stored hash, and every compressed file in the other comes out at its listed size, so every file opens.

Your copy is fingerprinted as four parts: `game`, `world`, `catalogue` and `community`. `world` is the map and everything it loads, and `catalogue` is everything you can build or hold, each following the game’s own record of what loads what, so a server running the map only asks for `world`. Every file matched Steam’s checksums or the archive’s own hashes.

## Known issues

- The game’s own links name 26 packages that aren’t in the install. They’re noted.
- Only the Windows build has been checked. The Linux build, the experimental branch, the Epic copy and the dedicated server haven’t been looked at yet.

## Next up

- Installing a mod through the community’s mod loader, to check how mods are laid out and whether anything keeps track of which are on.
- Checking the Linux build, the experimental branch, the Epic copy and the dedicated server.

## About Evil Engine

Evil Engine is a **passthrough modding** engine by Pushbar Interactive. Modding through the games you already own instead of around them: the content comes from each player's own copy and is never extracted, ported or redistributed. The term took off in September 2026 with mods that run two games at once and wire them together by hand, one pair at a time. Evil Engine comes from that lineage and makes the process repeatable: it learns each engine once, maps each game onto shared vocabularies once, and gives mods one API, so every mounted game works with every other.
