True Games Interactive and Petroglyph have announced that the Mytheon Open Beta will start on April 28th. Mytheon is a new free MMORPG that mixes together greek mythology with high fantasy. Until the open beta starts, anyone who registers on the website will be able to immediately play the game once it launches. Petroglyph also announced the “Champions of Mytheon” premium package that will give players who purchase it lifetime access to discount currency, premium offerings, exclusive, one-time only items, and sneak previews of new content before release. This exciting package will be available for purchase in early May.
