Services and development firm Keywords Studios has bought co-development outfit Certain Affinity. 

No figure has been placed on the deal, which was announced on the former's website. Certain Affinity has worked with a number of triple-A franchises, such as Halo, Call of Duty, Doom and Hogwarts Legacy. 

"We are thrilled to welcome Certain Affinity to the Keywords Group," Keywords boss Bertrand Bodson (pictured) said. 

"We have enormous respect for their business and reputation. They bring a wealth of knowledge, experience, and expertise to our Create division, complementing our existing skills and expanding our presence notably in the US and Canada. We look forward to partnering with Max, Paul, and their team over the coming years to continue to drive growth in our Create division and overall business."

Certain Affinity founder Max Hoberman added: "At this most difficult time in the market, we're thrilled to be able to provide stability and a supportive home for our team. The respect for our talent and culture that Keywords has shown, along with a willingness to invest in our growth, is unparalleled. Paul and I look forward to partnering with them to chart a course for careful expansion of our core co-development activities, refinement of our lead development capabilities, as well as championing the growth of the Create division.”
