Bethesda Softworks parent company ZeniMax Media has acquired Escalation Studios.
The Dallas-based studio, which was formed by Tom Mustaine and Marc Tardif in 2007, co-developed the SnapMap level editor featured in id Software's 2016 first-person shooter, Doom.
"We have continually been impressed with the team at Escalation that Tom and Marc have assembled," Bethesda VP of Development Todd Vaughn said. "Their commitment to quality and innovation has made significant contributions to the projects we’ve worked on together, and we’re excited to have them join ZeniMax."
Escalation Studios is already working on several projects with some of ZeniMax's other studios. While there's no word on which studios or projects the team is currently involved with, Escalation will aid in the development of console and PC games, as well as titles for mobile and virtual reality.
