Final Fantasy: Airborn Brigade takes place in an ancient kingdom, responsible for guarding crystals, which is invaded by monsters. Each player rides an airship and players can form groups called airborne brigades to fight bosses together. The goal is to restore to lustre of the crystals, which have lost their radiance.

What bosses? Ifrit, Shiva, Bahamut, and Odin are all in the game. Each player gains experience and levels up as you go along, and there’s a PvP element in the game, too, where your party can fight your friends.
