Team shooter Deep Rock Galactic has sold more than two million copies to date.

That's according to developer Ghost Ship Games, who revealed the milestone on the title's Steam page. Deep Rock Galactic was released into Early Access on Steam back in February 2018 ahead of a 1.0 release in May 2020.

Deep Rock Galactic saw a surge in popularity before and around its full release last year and was the sixth best-selling title on Steam following its launch out of Early Access.

The studio says that on average, its users on Steam have spent 31 hours and seven minutes playing the game, while players spent an average of 88 minutes per session with Deep Rock Galactic in 2020.

The shooter boasted 310,000 monthly active users in 2020, an increase on the 110,000 it had in 2019, while sales tripled year-on-year.

"Before we launched into Early Access, we reached an internal agreement that 200,000 units sold during the game's lifetime would be suitable, and would allow us to continue and do a new game," Ghost Ship wrote on Steam.

"But now we just crossed two million units sold, and the game is performing stronger than ever - not only in sales, but also in the strength of the community. When reading a random thread on gaming and suddenly one user comments "Rock and Stone", causing the whole thread to explode in rock-and-stone shouts, then you know you've created something extraordinary and transcending. And the "we" does not only mean us developers, but also very much you, the community around Deep Rock Galactic. From the bottom of our hearts, we thank you."
