Swedish developer-publisher Paradox Interactive has acquired French "mobile-focused" developer Playrion Game Studio for an undisclosed fee.

Paradox has built up a reputation as something of a strategy specialist on PC and consoles, having put its name to titles like Stellaris, Cities: Skylines, Europa Universalis, and Surviving Mars.

Its latest acquisition, however, suggests a notable change in direction for the company, which has only made baby steps into the mobile arena with a handful of titles like Prison Architect: Mobile and Stellaris: Galaxy Command -- the latter of which endured a bumpy launch. 

Playrion is best known for supporting the development of Airlines Manager, which has amassed 10 million players since launching on smartphones in 2014. Paradox chief operations officer Charlotta Nilsson said Playrion's pedigree on mobile would help the company bring more of its games to the platform. 

"Adding Playrion to our roster allows us to continue expanding our business in new areas, and bring more of our IPs to mobile," commented Nilsson. "We’re always thrilled when we find teams who want to make the kind of games we’d like to make ourselves."
