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.

The Mythos quest system lets players play a part in the story of the first worldwide Hack´n´Slash  MMO. The many diverse quests can be carried out either by plucky lone adventurers, or in groups of up to five players. There are rewards to be had in the form of abundant experience points, or special items which will also enable faster levelling.

To fulfil the quests players can enter gloomy dungeons to teach monsters the meaning of fear, or travel the fantasy laden world of “Uld” to search for raw materials. On their travels players can also complete errands, save NPCs or use special abilities to dispatch nasty boss monsters. Since manufacturing items is also a component of many quests, products from the virtual blacksmith’s hammer can be crafted from either gathered or looted raw materials. Successfully completed quests will earn adventurers some useful rewards and also valuable objects handed over by the grateful NPC population. Through the experience points they receive at the same time, players not only increase the value of their inventory, and also move on more quickly to the next level.

For those for whom experience points or valuable armour and weapon components aren’t enough, they ought to keep an eye on the numerous factions in the game. This is where the player can take on special tasks in order to raise their reputation within a faction. Once the player has achieved a certain level, they then gain access to special merchants who can offer them a range of exclusive and powerful items.
