Fallen Earth: Welcome to the Apocalypse

Fallen Earth is a free-to-play MMO developed by Reloaded Productions (formerly by North Carolina-based Icarus Studios and Fallen Earth).[2] The game takes place in a post-apocalyptic wasteland located around the American Grand Canyon. Fallen Earth's gameplay features FPS/RPG hybridization, first-person/third person views, hundreds of items, including improvised equipment and weapons, a variety of functional vehicles, a real-time, in-depth crafting system (which includes vehicles), various skills and abilities, factions and tactical PvP, all existing within 1000 square kilometers of usable terrain based on real-world topographical maps of the area. The game was released on September 22, 2009. Two years later, GamesFirst purchased the intellectual property and made the game free to play.
