About Earthfall

Earthfall is a four-player cooperative shooter set during an extraterrestrial invasion that leaves humanity an endangered species. You fight through the Pacific Northwest with friends or AI teammates in a guerilla war against alien drones and their inscrutable masters, trying to save what remains of humanity.

Co-op campaign

The game has 15 levels of story-driven cooperative play. You can drop in and out of four-player sessions, and fight a procedurally generated alien horde that changes between sessions.

Weapons and defenses

You use futuristic weaponry, including printable guns, to battle the invasion. You can build barricades and upgrade them with fire or electricity, as well as control mounted turrets.
