Undead Labs’ Xbox One and PC gameState of Decay 2is rough around the edges, with several major bugs and a general lack of polish, but the zombie survival title has still managed to attract a huge audience. Since its release,more than 1 million playershave gotten lost in the apocalypse.

This number factors in players who purchased the game’s Ultimate Edition — released on May 18 — as well as the standard version released on May 22. It also includes those who played the game through an Xbox Game Pass subscription.State of Decay 2and all other Microsoft-published Xbox One games are available via the program on the same day they launch.

“Across player communities, we’ve seen survivors kill over 675 million zombies, throw over 6 million firecrackers and fireworks (survivors still find ways to celebrate), eat over 6 million bags of snacks, read over 2 million textbooks, and typically survive for about three days,”said Xbox Games Marketing GM Aaron Greenberg, who added that some have survived for a full month.
