Atlantica is a turn based, strategy MMO from a Korean developer. The company behind the game made strategy games throughout the 90s before turning to MMO creation, so it was a natural fit. The game allows you to hire up to eight mercenaries to fill out your party and aid you in your battles, be they PVE or PVP.
