The Nintendo 3DS role-playing game, which is due to launch on June 15, can be pre-ordered from the GAME website for £34.99.
Heroes of Fortune features multiple classes, co-operative multiplayer and dynamic dungeons that change each time they are played.
The game will also host free downloadable content, with daily updates planned for an entire year. Additional content includes new levels and quests.
N-Space is developing the title, which will be published by Square Enix worldwide.
The announcement comes after it was revealed that GAME would stock an exclusive edition of Assassin's Creed 3, complete with a bonus mission and weapon.
