OpenApoc - Open Source X-COM: Apocalypse

About OpenApoc - Open Source X-COM: Apocalypse

OpenApoc is an active open source project rebuilding X-COM: Apocalypse from 1997 in C++ using SDL2. The Discord server is where the development team coordinates work and players follow progress on the remake, which requires the original game files to run and is licensed under GPL3.

The project has been in development since 2014 and is currently in alpha—the core game is playable but not all original features are implemented yet. The server functions as the central hub for contributors, whether programmers working on the codebase or players testing builds and tracking milestones. If you're interested in retro game preservation, C++ game development, or want to contribute to an established open source strategy game project, this is where active work happens.
