Games firm Keywords is once again making acquisitions.

The company has just purchased games development Sperasoft for $27m. That outfit has worked with giants of the industry such as EA, Ubisoft, Warner Bros and Riot Games. Recently its St Petersburg studio was one of six studios working on the recently-released Assassin's Creed: Origins.

“Sperasoft adds considerably to our engineering services division which we intend to continue to build organically and through acquisition, as well as significantly enlarging our range of services and geographic footprint," Keywords chief Andrew Day said.

"We are delighted to welcome Sperasoft to the Keywords family and we look forward to working closely with their highly talented team to build upon their strong industry reputation and relationships with some of the world’s leading games developers and publishers.”

Sperasoft CEO Igor Efremov added: “We are delighted to be joining Keywords Studios in a union that we believe will enable Sperasoft to grow and expand our offering to our existing partners as part of a larger group. We look forward to working with other members of the Group as we are confident that our vision and commitment to providing the very best support to the video games industry is very much aligned."

This is but the latest acquisition that Keywords has made in recent memory. In May it snapped up XLOC, before spending $4.8m on GameSim. In October it purchased both work-for-hire studio d3t and QA company VMC.

In the 2016/17 fiscal year, it also bought eight companies. In the 2017 calendar year, Keywords has splashed out in the region of a cool $118m on new purchases.
