Gameplay
Fantasy Earth: Zero has a player-versus-environment element, but experience is awarded at a much slower rate than in KvK battles.
KvK battles have many elements that are similar to those found in real-time strategy games. Players "mine" crystals by crouching next to a giant crystal. After a certain number of crystals are mined, players must trade with each other to get the number of crystals they need to build a structure or summon a unit of war. Units of war are summoned much as they are in Final Fantasy games, but the Wraith and the Giant require structures to be built before they can be summoned. When a player character summons a unit, they assume the form of that unit and directly control its action.
Several buildings can be built on the battlefield, each with its own purpose. Obelisks are used to capture enemy territory. Eclipses can expand further into overlapping territory. Scaffolds can be built as a jumping platform. Bulwarks are used to block enemies from a certain area. Gates of Hades are required to summon Wraiths; War Workshops, to summon Giants. Arrow Towers attack nearby enemies to reinforce the front-line.
