NHN USA announced that Atlantica Online has been added to the ijji.com portal, through a partnership with NDOORS Interactive. Atlantica Online is a MMO using a turn-based combat system, offering players the chance to strategically plan every move of the nine characters in their group. Players can form teams of three to bring 27 controllable characters into combat. For simple fights, players can also preset each character/mercenary's skill set and let the auto-battle system resolve the fight. The mercenary system gives players the chance to manage multiple characters' development simultaneously.
