Zombie action franchise Dying Light has sold over 30 million copies since its 2015 debut.

That's according to developer Techland, which revealed the sales milestone 12 months after the release of the second entry in the series, Dying Light 2 Stay Human.

"The team continues to demonstrate their unwavering commitment to create unforgettable experiences for gamers worldwide," chief creative officer, Adrian Ciszewski said. "We're not stopping here and will continue to support the game with amazing content for years to come."

Chief publishing officer Oleg Klapovskiy added: "These outstanding numbers speak for themselves and confirm the success of the Dying Light franchise. We were able to achieve it only thanks to our awesome community. I want to use this opportunity to thank them again for their great support. We have ambitious plans not only to develop and further support the game, but also to expand to other medias."

Dying Light was originally released back in 2015.
