State of Decay — Year-One Survival Edition is an action-horror game with a third-person view and stealth elements. The developers have added new weapons, vehicles and characters for this version of the game. A new mission type has also been added and visual effects, animations and user interface have been improved. There is also a new type of mission in which a Mysterious Organization drops supply crates on the map in random locations. Although these crates contain some of the best weapons in the game, they are extremely difficult to open as they attract a huge number of zombies and freaks. You'll also be able to read a variety of signs placed throughout the world, some of which include nice backstory, such as a gas station going out of business before the zombie apocalypse. The user interface has been cleaned up to bring out features that were previously buried. Each character in the game has a number of traits from their past life before the apocalypse.
