It's a free-to-play, massively multiplayer web-based game focusing on resource management and diplomacy in a persistent virtual world, called Ashan. You can form alliances with other players and wage war as you vie for supremacy. Sadly, the game's only available in the United Kingdom, Germany and France right now. If you live in one of those qualifying regions, you can download it now, free of charge.
We've contacted Ubisoft to see if and when it'll be available in the US. We'll let you know what we hear back.
