Players in Tactica Online will be able to travel and find missions in an overworld that will then send them into an instanced mission dungeons. Dungeons are generated somewhat randomly, but will follow a certain set of requirements based on the mission. In an interesting turn of events, players will then be matched with opponents across the globe through a ladder matching system based. Someone who received the other end of that quest and is around your level will be tossed into the same instance and will battle it out with the players.
