State of Decay 2 has always been exclusively available on the Microsoft store since it was launched in 2018. We are happy to say it will be arriving on steam on Friday the 13th of march 2020.
This State Of Decay 2 overhaul release will be the “Juggernaut Edition” which is an impressively expanded version of the original. Apparently, the Microsoft store version will receive an upgrade as well.
Juggernaut Edition is also available for all Xbox Game Pass members, and launching for the first time on Steam with cross-network play across all platforms.
In this Juggernaut Edition we will be receiving some bug fixes, a new category of heavy melee weapons, some graphic enhancements, new music added, a new open world map of a rugged logging town Called providence ridge and an enhanced post-tutorial experience to introduce the new mechanics.

The State Of Decay 2 overhaul also comes with three new DLC’s. The heartland DLC, the daybreak pack and the independence pack for our pleasure.
Those who already bought the DLC separately will receive “some exclusive in-game gifts that won’t be available anywhere else” on launch day. https://bit.ly/2UWS2Mc

I must say this is an exciting prospect as an improvement on this already amazing game; it can only be mind-blowing.
