About
Oddworld: Abe's Oddysee (1997) and its sequel Oddworld: Abe's Exoddus (1998) are platform games by Oddworld Inhabitants, originally released for PlayStation and MS-DOS/Windows, with later Game Boy versions. R.E.L.I.V.E. is an open-source engine replacement for Oddworld: Abe's Oddysee and Abe's Exoddus, aiming for full compatibility with the original games while fixing bugs and eventually adding modding and level-creation support. It targets Windows, Linux, and macOS and requires the original game data to run.
How it differs from the original
Beyond fixing the original games' bugs, the project intends to add a modding and level-creation interface that the originals never had.
Getting started
Clone the repository recursively (it uses submodules), create a build directory, and build with CMake and SDL3 — the project provides step-by-step instructions for Visual Studio 2022 on Windows and for native Linux builds. In Abe's Exoddus, F5/F6 provide quicksave/quickload, F10 toggles a screen filter, F11 keeps aspect ratio, and F12 toggles fullscreen.
