A GameMaker Studio 2 (GMS2) decompiler is a software tool designed to reverse engineer compiled game executables (.exe, .apk, .ipa, .wasm, etc.) back into a human-readable, editable project format. Unlike simple asset extractors, a full decompiler aims to reconstruct the original GameMaker Language (GML) source code, sprites, objects, rooms, scripts, and other assets from the final compiled game.
Decompiling GMS2 games is technically feasible to varying degrees, but fraught with legal, ethical, and technical challenges. For legitimate needs (project recovery, authorized modding, security research), prefer lawful channels, backups, and permission from rights holders. For developers, the best defense is sound project backups and avoiding sensitive logic on the client. gamemaker studio 2 decompiler
