Allods Online is a free to play massively multiplayer online role-playing game currently in development by Russian online game developer Astrum Nival. Based on the popular Allods series of games (known internationally as Rage of Mages) and featuring eight playable character classes, six races and an expansive and compelling world, it is set to win the hearts of gamers worldwide. The title’s unique setting features magical islands called allods that float in the living substance known as the Astral. With fierce player versus player and player versus environment combat plus epic battles between Astral ships, Allods Online offers a traditional fantasy MMORPG experience with a new science fiction twist.
