Become a Scorpion warrior and battle hundreds of beasts in freemium 'console quality' RPG.
The RPG boasts the 'appearance of a console game' and invites users to become one of six warriors (Scorpions), with the player challenged to save the land from a demonic reign of terror.
The dark world has more than 100 beasts to defeat, as well as a number of mini-quests to complete, before the user inevitably has to face the demon waging war on the region.
Use of the GREE Platform means the app will launch in English, French, German, Italian and Spanish, while social leaderboards and achievements will also be integrated.
Kyoko Matsushita, VP of EMEA marketing and developer relations at GREE UK, said: "Mail.Ru Group developed an amazing game that we are proud to be a part of. Juggernaut for GREE takes advantage of GREE Platform's social interactions and possibilities and we are working closely with Mail.Ru Group to evaluate other exciting collaborations in the future."
