Included in the Year One Survival Edition is the original State of Decay, as well as the the two DLC pieces which released later – Lifeline and Breakdown.
The retail version will also include:
A special premium clamshell box The game (and two pieces of DLC) on a disk (Steam code included). A double-sided State of Decay A3 poster The soundtrack supplied via the ancient CD
All of this will set you back $19.99/£14.99 (estimated)/€19.99, which is less than the price of the game digitally.
State of Decay originally released on Xbox 360 in September 2013, then for Windows in November of the same year, to much critical praise – earning a 79/100 metacritic rating for the PC version, and just 1 point less for the Xbox 360 version.
A few years later, and after receiving two pieces of DLC, the Year One Survival Edition was released. This brought State of Decay to the Xbox One, and an upgraded version to Windows, with 1080p textures and bug fixes.
State of Decay 2 was revealed at Xbox’s E3 2016 presser. It will feature co-op, and is set to release in 2017.
