Stratagus is a free cross-platform real-time strategy gaming engine. It includes support for playing over Internet/LAN, or playing vs. computer opponents. The engine is configurable and can be used to create games with a wide-range of features specific to your needs.

Stratagus started as a clone of the realtime fantasy strategy game Warcraft II from Blizzard Entertainment, although it is used now as a game engine to build other games, sci-fi or fantasy ones.

Stratagus is developed together for Windows, Linux and Linux Maemo based devices (Nokia N900).
