Guerrilla Games has been working on a new project that isn't Killzone for two and a half years.
Executive producer Angie Smets mentioned the new game in a video from Sony Japan which introduced the team behind Killzone Shadow Fall to Japanese gamers, who reportedly bought 320,000 PlayStation 4 systems in two days after its February 22 launch.
"We are working on a new IP, we started on that already two and a half years ago," Smets said. "Unfortunately we cannot share details of the new IP, so you'll have to be a bit more patient until then."
The Amsterdam-based studio has worked exclusively on the PlayStation-exclusive sci-fi shooter series, with the exception of ShellShock: Nam '67 in 2004. It was acquired as a first-party developer by Sony Computer Entertainment in 2005.
Guerrilla released a patch for Killzone Shadow Fall in early February which added clan support to the multiplayer mode and an option to lock the single-player mode to 30 frames per second.
In our Killzone Shadow Fall review, we found that "it doesn't seek to reinvent the FPS, but it does inject a much-needed infusion of creativity and originality into the genre."
