Mythos will be available only via digital distribution, and will be free to players. The massively multiplayer technology in Mythos is partially being used as a testbed for the multiplayer components of Flagship Studio's upcoming title Hellgate: London (Hellgate: London interview). Like that heavily anticipated game, Mythos draws inspiration from Blizzard's Diablo franchise, on which many Flagship developers worked. With its isometric perspective and fantasy environments, Mythos shares more in common visually with Diablo than does Hellgate: London. Flagship sent along a batch of Mythos sccreenshots.

"For Mythos, we started with the revolutionary style of gameplay we pioneered in the Diablo franchise. Then, by offering it free to download and play, we make it even more accessible to players," said creative director Phil Shenk. "By designing the Mythos world from the ground-up to be an ever-changing place, we can quickly and seamlessly implement new ideas from a variety of inspirations. Through the continued support of the Flagship community, we are striving to create what will be one of the most innovative role-playing games of recent years."

The fairly traditional fantasy world of Mythos is heavily instanced, and is said to cater to both solo and group play. Players may choose to play as a Human, Elf, or Gremlin; specific classes were not named.

Mythos is slated for North American and European release later in 2007.
