Lugaru: The Rabbit's Foot

Lugaru: The Rabbit's Foot (pronounced Loo-GAH-roo) is the first commercial video game created by Wolfire Games. It is a cross-platform, 3D action adventure game for Microsoft Windows, Mac OS X, Linux. It features Turner, an anthropomorphic rabbit with curiously well-developed combat skills.

Lugaru was made almost solely by David Rosen, including the game engine, models, animations and story. It was one of the first independently-produced video games to employ ragdoll physics. It uses a new and fairly intuitive combat system, basing attacks and counters on timing and context rather than different key combinations. It tended to be well-reviewed and was fairly well-received among the shareware community, especially among Mac users. Tim Soret would later improve the games textures, and Wolfire currently sells this version as Lugaru HD.
