Swedish publisher Paradox Interactive has acquired the rights to Prison Architect from Introversion Software.
"Ever since our partnership with Introversion in 2017, the Paradox team has felt that Prison Architect is a natural fit for our catalogue,” said Paradox Interactive CEO Ebba Ljungerud.
“Just as we’ve done for other management-strategy games like Cities: Skylines and Surviving Mars, I believe the considerable player base of Prison Architect will be excited to see where we can take the game next, and we’re eager to explore development of potential new games based off of the ‘Architect’ IP.
Ljungerud added that his team "promise to exercise good behaviour with this cherished title going forward.”
Prison Architect tasks players with the construction and maintenance of a maximum security prison, from laying out cell blocks and inmate facilities to managing staff pay and prisoner morale.
It originally launched as a paid alpha on PC in 2012, with a full release in 2015.
Since then, Prison Architect has won a BAFTA in the 'Persistent Game' category, and has release on consoles, selling more than two million copies to date.
“Prison Architect has been an intensely rewarding project for us,” said Introversion co-founder Mark Morris.
"Through Early Access, launch on multiple platforms and over a dozen post-launch content updates, we’ve been building and managing this building-and-management game for nearly a decade.
"I think we’ve taken Prison Architect just about as far as we can, and we’re all eager to see where a team like Paradox can take it next."
Morris added that by passing the torch on to Paradox Interactive, it frees Introversion up to focus on upcoming projects.
