EARTH DEFENSE FORCE 6 casts players as EDF soldiers in a battered future where humanity is struggling to recover from an alien invasion. The story moves from the apparent defeat of the Primers to a new crisis in 2027, as survivors confront threats in a devastated world. Its bleak setting frames the series’ familiar central task: defending Earth against giant enemies.
Combat is presented as a third-person shooter built around destroying large numbers of foes. Players can choose among four soldier classes, then take those distinct roles into missions equipped with weapons. The game’s scale is part of its pitch: it includes the series’ largest number of missions and weapons, while its story reveals the identity of the invader that has tormented Earth.
Every mission supports online co-op for up to four players, with the option to fight alongside other EDF members. The store also lists single-player and shared or split-screen play, giving the game both solo and local options alongside online teamwork.
