Call of Duty veteran Michael Condrey started a new game studio temporarily called 2K Silicon Valley in early 2019, and now the studio has an official name: 31st Union.

The team has dozens of employees, including a number that used to work at Sledgehammer Games, the San Mateo, California-based studio that Condrey cofounded with Glen Schofield to make Call of Duty games. They made blockbusters such as Call of Duty: Advanced Warfare and Call of Duty: WWII. Both founders left Sledgehammer, and they have started their own separate studios.
