Redbana US' global manager Eric Liu revealed in a recent interview that they are still working out the game's price structure, but that it will most likely include micro-transactions.

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.

In 2008, the Mythos beta was closed to the disappointment of the game’s many fans. HanbitSoft acquired the intellectual property and parent company T3 Entertainment resumed development, with the game now in closed beta in South Korea.
