Slipgate Studios

Formerly known as Interceptor Entertainment the company was renamed to Slipgate Studios in 2017. The new name was already being used by a VR company in the United States and to resolve the issue the company was renamed again in 2019 to Slipgate Ironworks after taking over the name and trademark from John Romero, who had created a company under the name in 2006.
