Mythos is an online, action role-playing game that is free to download and free to play. Set in the land of Uld – a fantasy world arising from the ashes of an epoch-long war of darkness – players assume the roles of fantasy heroes as they explore, adventure, and quest through entirely randomized dungeons and environments. With an elegant point-and-click interface and an accessible "isometric" perspective, Mythos is poised to have near-universal appeal. The game allows thousands of players to interact within the same world while using mostly "instanced" dungeons to create unique gaming experiences suited for both solo and group-minded players.

As players journey into Mythos' ever-expanding universe, they select one of four races (Human, Satyr, Gremlin, or Cyclops) and opt to play as a particular character class using a huge variety of skills and items. Through heroic quests players search for gold, gems, armor, and weapons, while unlocking the secrets of Uld. Mythos presents a constantly expanding, continuously updated world where something new lurks around every corner.
