Fallen Earth is a massively multiplayer online role-playing game (MMORPG) set on a post-apocalyptic Earth in the year 2156.
Within the Grand Canyon Province, an isolated pocket of settlements around one of the world’s most amazing landmarks, you’ll face threats to mankind’s continued survival, including everything from irradiated zones to mutated beasts to raiders. Six factions struggle for dominance in the Province. Over time, you’ll have the chance to pick a side in the effort to hold sway over what remains of the post-Fall world.
The game went free to play in October 2011. Premium memberships among other things are now available via Gamersfirst.
