State of Decay 2 released in May last year to less than stellar reviews, mostly due to the amount of bugs, but it quickly passed the million player mark in just a week. Instead of dropping off from that high point, the game's player count continued to rise - reaching three million players by July 2018, just in time for the US's Independence Day, and four million by the end of the year.
Since 2018 State of Decay 2 actually continues to Grow, albeit more slowly than in its first few months - and now it's reached a new milestone. According to Undead Labs' Quin Richards, senior designer on State of Decay 2 in an interview with Polygon, the game now boasts over five million players - and the team is still "looking for grow".
As Richards explains, "we’re in a really great position where we’ve gotten to keep adding players to the game. We’re [at] five million players, and we’re looking to grow."
