Upcoming Xbox console exclusive game State of Decay 3 could be getting its first major update in four years. State of Decay 3 was first announced in 2020, and was in fact one of the first-ever games revealed for the Xbox Series X/S family of consoles. The CG trailer helped set the tone for what State of Decay 3 may be aiming for thematically, but otherwise didn't reveal anything all that substantial about the game.
