The world of Aika features five nations — each possessing its own distinct personality and populated by thousands — which, along with a comprehensive guild system, lays the groundwork for truly epic military clashes. Guilds and nations may ally with each other in exciting Castle Sieges to gain control of a nation and lord over its subjects, while entire nations may scheme with and against each other to win wars with glory, treasure, and powerful ability enhancements at stake.
Aika presents three major PvP modes which run the gamut from small skirmishes to 1000 vs. 1000 warfare.
