Earth Defense Force 2017

The game's story places the player in the role of an EDF infantry man tasked with defending the Earth from hordes of alien invaders. In 2017, the player must fight against aliens on city streets, in underground caves and on coastal zones. The game features 53 missions where you fight against aliens.

You unlock new weapons throughout the game by picking up Weapon objects, dropped by killed enemies. Weapon objects provide random weapons including those the character already has. On some maps there are also helicopters, battlemechs, tanks and bikes that can be controlled.

The Xbox 360 version features 2-player split-screen multiplayer where you can play cooperative or versus battle. The PS Vita version has an online cooperative multiplayer mode for up to four players. Also, the Vita and Switch versions of the game have a few extra levels and weapons, and an unlockable extra character: the Pale Wing.

Earth Defense Force 2017 is the first game in the series that features AI controlled EDF forces on its maps; in both previous games, the player fought completely by themselves. The radio chatter from the Japanese version was retained for the English release.
