Unciv is a 4X strategy game that remakes Civilization V as an open-source, moddable title for Android and desktop platforms.
The project addresses the gap between faithful Civilization V gameplay and accessibility on lower-end hardware and mobile devices. Rather than pursuing high-fidelity graphics and audio, Unciv prioritizes a lightweight footprint, fast performance, and deep moddability. Built with LibGDX, it delivers the core 4X experience—civilization building, turn-based strategy, and technology progression—while remaining playable on modest systems. The README explicitly positions itself against the original Civilization V, acknowledging that players seeking high-resolution graphics, soundtracks, and animations should choose Firaxis's official game instead.
Unciv suits players who value moddability, portability, and open-source principles over production polish. It runs on Android, Linux, Windows, macOS, and Raspberry Pi, with installation available through multiple channels including app stores, package managers, and direct downloads. The project is actively developing toward feature parity with Civilization V's expansions, with a roadmap that includes UI and UX improvements, better AI automation, and eventually the mechanics from Gods & Kings and Beyond the Sword. The README makes clear that features not present in the original Civ V will not be added to the base game but may be implemented as moddable extensions.
Almost all open issues are raised by users rather than the core team, reflecting a substantial player base reporting real-world use. Maintainers typically respond to new issues and pull requests within a day. Work in the issue tracker centers on bug fixes, feature requests, and resolved items, indicating active triage and closure of reported problems.
