The Warsmash project is developing an alternative open-source game engine for Warcraft III, capable of recreating the gameplay in the presence of the original game on the system (requires game resource files included in the original Warcraft III distribution). The project is at the alpha stage of development, but already supports both single-player passage and participation in online multiplayer battles. The main purpose of the development is to simplify the creation of Warcraft III modifications and experimentation. The code is written in Java using the libGDX game development framework and distributed under the MIT license. Supports running on Linux and Windows.
