The team behind Sony’s first-person shooter series Killzone is creating something new, according to Eurogamer. The company is currently finishing development on Killzone: Shadow Fall, a launch title for Sony’s upcoming PlayStation 4 system (which comes out on Nov. 15).

“As a studio we do want to branch out, and we have started work on a new IP, something completely different to Killzone,” Shadow Fall lead designer Eric Boltjes told Eurogamer at  its recent Eurogamer Expo. “I don’t want to say anything about it right now, but as a studio we do want to keep it fresh.”

This would mark the studios first non-Killzone project since that franchise started on the PlayStation 2 in 2004. The series has seen three console releases (not counting the upcoming Shadow Fall) and two portable installments. Boltjes would not go into specifics regarding the new IP. We have contacted Sony for more information.
