Eurogamer: As Killzone Shadow Fall gets co-op, Guerrilla plots future on PS4

Guerrilla Games is busy working on a significant four-player co-op expansion to its PlayStation 4 launch title Killzone Shadow Fall - but it's also busy working on its secret next effort on the console.

According to the Dutch developer, its next game will benefit from its creators having had plenty of experience with the finished version of Sony's console. It was a different case, of course, with Shadow Fall.

Speaking with Eurogamer, Guerrilla producer Poria Torkan said making a PS4 launch title was particularly difficult because the developer was working with ever-changing hardware and software - even though, as a Sony-owned studio, it was as close to the console as could be expected.

"The best metaphor for making a launch title is it's like driving a race car while the car is still being built around you," Torkan said.

Beyond Shadow Fall, Guerrilla is working on a new intellectual property for PS4, rumoured to be an open world role-playing game. This game has been in the works for some time, although Eurogamer understands next month's E3 trade show may come too soon for a reveal.

Back in September, Shadow Fall lead designer Eric Boltjes told Eurogamer this new game is "completely different to Killzone". "I don't want to say anything about it right now," he said, "but as a studio we do want to keep it fresh."

Similarly, Torkan kept Guerrilla's cards close to his chest. "It's really awesome!" he said. "It's exciting times. If I even say one word people will kill me."

Whatever the case, we can expect Guerrilla's next effort on PS4 to go one better than Shadow Fall - at least in technological terms.

"If you compare Shadow Fall to the first games on the PS3, so if this is like the first generation of games which are coming, god knows what they will be like in four or five years," Torkan said.

"Compare the first games that came out on the PS3 to The Last of Us or GTA5. It's amazing. That's the thing. We had two-and-a-half years to figure out what we wanted to do with our engine and one-and-a-half years to figure out what we wanted to do with the hardware. Imagine when comparably technically advanced studios get four or five years under their belts with the hardware.

"We'll get our chance!"

Good, At least someone understands that waiting till the game is ready to be announced instead of just announcing it prematurely and then delaying it for ages is the right thing to do

I'm ok with that. Sick of reveals for games that don't come out for two or more years after

Calling BS. At the time of E3, the game is in development for ~3 years, if they don't have something to show then I'm gonna get worried.

I suspect it is a bit of a cat and mouse game right now... with all the fake leaks etc, why not put some of their own out there :)

Just because you're announcing something doesn't mean you have to give an unnecessarily premature release window. For example, Watch Dogs and The Division had awesome E3 reveals......Ubisoft just decided to put time stamps on both that neither was able to meet, but that didn't make the reveals any less impressive.

If the order 1886 dont get released in 2014 then I will probably go nuts. I still want a proper game rather than a broken game released early. But my frustration wont decrease.

Agreed, gives us something to look forward to as well

Ya save it for Gamescom, i believe E3 already have much enough to show...

yup, I'm expecting to see this in some form at E3 this year, or worst case scenario at GDC in august. Playable at E3 next year and launching fall next year too. To not show this year at all means that the game doesn't come out till 2016. Just don't see that happenning especially since they have been talking about working on this game for the past 3 years for over 2yrs now lol.
