Adventure game Firewatch has passed a major sales milestone.

Developer Campo Santo announced on Twitter that the game has now sold more than 1 million copies. The millionth copy was sold sometime in late 2016, the developer said. As announced previously, Firewatch sold 500,000 copies in its first month.

Firewatch launched in February 2016 for PC and PlayStation 4, before landing on Xbox One in September of that year. It was Campo Santo’s first title and reviews for the first-person adventure game were positive across the board.

A Firewatch movie is currently in the works at Good Universe, the film company that also produced the well-received horror movie Don’t Breathe and Last Vegas. The game, which sees players adventuring through 1989 Wyoming as part of a mysterious story, features the voices of Cissy Jones (The Walking Dead) and Rich Sommer (Mad Men).

GameSpot’s Firewatch review scored the game a 7/10.

"Its world is captivating, its design is clever, and its characters are among the most well-written in gaming," reviewer Scott Butterworth said. "Though it might sound counterintuitive, the plot is in many ways secondary to the relationship you build between Henry and Delilah, and that portion of the game is truly inspired. I’ve already returned to Firewatch for a calming walk in the woods; I imagine I’ll go back again soon to visit with Henry and Delilah."
