About

Duck Game Rebuilt is a decompilation of Duck Game with substantial improvements to performance, compatibility, and quality-of-life features. It's built in C#/.NET (Visual Studio on Windows, Mono on Linux) and distributed for Windows via a Steam Workshop mod and for Linux via a dedicated installation guide.

How it differs from the original

As a decompilation-based rebuild rather than the stock executable, it adds performance, compatibility, and quality-of-life improvements over the original Duck Game, tracked in the project's own changelog.

Getting started

On Windows, it's installed by subscribing to a Steam Workshop mod; on Linux it requires following a dedicated installation guide involving Mono. Either way, Steam must already be running before launch, or the game will crash on startup.

What you need to run it

Original game files required. The project ships code only; you provide your own copy of the game. Requires Steam and the original Duck Game to be installed.

Steam must be running when you launch the game.

How to install

On Windows, subscribe to the Steam Workshop mod.
On Linux, follow the Linux Installation Guide.
