Sledgehammer Games invades the UK with new Call of Duty studio

Sledgehammer Games has been dramatically expanding during its second decade as one of Activision Blizzard’s major Call of Duty development studios. And now it’s expanding into the United Kingdom with a new studio in Guildford, U.K.

The San Mateo, California-based company is leading the launch of Call of Duty: Vanguard, and it is now in its second decade of operation as one of the major studios on the Call of Duty franchise, which has sold more than 400 million copies to date. As Call of Duty expands with Warzone, Zombies, premium games, and Call of Duty: Mobile, so too do the development tasks.
