One of Naughty Dog's longtime developers and programmers, Christian Gyrling, is leaving the Last of Us and Uncharted development studio after a 17-year-long career at the company. The former employee was the studio's former head of technology, who made many contributions to the games developed, along with holding a lot of different positions during his time at Naughty Dog. Gyrling first joined the company as a programmer for the first Uncharted game on the PS3 back in 2007.
