State of Decay: Year-One Survival Edition

State of Decay is an action-adventure survival horror stealth video game developed by Undead Labs and published by Microsoft Studios. It places emphasis on how the player's leaderships skills fare against an onslaught of problems, such as diminishing survival resources, group trust and morale, zombie extermination, base defenses, and people’s lives. The game also combines elements of shooters, stealth, role-playing and strategy games and the game challenges players to survive by exploring, scavenging, and fighting the undead.

State of Decay: Year-One Survival Edition is the first release of the game for the Xbox One platform and a compilation release for the PC as most of the content was already available separately. It contains:

- State of Decay (base game)

- State of Decay: Breakdown (DLC)

- State of Decay: Lifeline (DLC)

The graphics were remastered from 720p to 1080p with new animations, improved lighting, textures, combat mechanics and an extended drawing distance. It also adds a knife as a new melee weapon. There are new missions as supply crates with rare content can now appear, also drawing large hordes of zombies. Characters from Lifeline can now be unlocked in Breakdown, including the previously unplayable Kelly 'Sasquatch' Eldridge. The game contains a new SUV as well as custom vehicle skins distributed across all maps. New weapons include new assault rifles with under-barrel grenade launcher attachments as well as shotguns that fire incendiary rounds.

The Xbox One version has unlockable items through timed community challenges and achievements covering both the base game and the DLC. For the PC version owners of the original game on Steam can upgrade the regular version to this one with a 33% discount.
