While we already got a pretty damn good Final Fantasy for 3DS, Square Enix has revealed another Final flavored project -- Explorers, by way of Jump Magazine. It's a multiplayer action RPG involving crystals, summons, and multiple jobs. So far the Knight, Monk, Black Mage, and White Mage classes are confirmed.
Four player co-op is a thing, and apparently all jobs will need to work together to really succeed. The summons are the core enemies in the game, and the idea is to defeat every generation of these archfiends. It's heading to 3DS at some point -- no word on a release date or localization.
