Mythos
Mythos is an online action role-playing game that you can download and play for free. Set in the land of Uld - a fantasy world created from the ashes of an epochal war of darkness - players take on the roles of fantasy heroes as they explore, adventure, and fight their way through completely randomized dungeons and environments. With an elegant point-and-click interface and an accessible "isometric" perspective, Mythos will be nearly universal.
