Killzone 2 for the PlayStation 3 gave developer Guerilla Games no end to headaches, as Sony gave the studio an impossible task of matching the lifelike CGI in the video.
The studio maintains that the Killzone: Shadow Fall trailer shown at the PlayStation 4 reveal was all real.
According to co-founder Hermen Hulst, “That was one thing where we went ‘Okay, next time around we’re going to be on a stage we’re going to make sure it’s real.’” Technical director Michiel Van Der Leeuw piped in, “We actually made a point of not even claiming it was real, it was as a matter of course that it was real."
Leeuw added, “I think everybody was onboard with that, there was so much drive for people to make things real. We were working with central in London and the guys in Japan, fixing the firmware to make sure that the Facebook upload would work. It doesn’t get much more real than that.”
The developer didn't even bring a backup video in case the live demo crashed.
"We fixed three bugs in the last day that were very, very rare and only happened like once in a hundred playthroughs, but we knew that three of those bugs were in there. So theoretically, there was like a three in a hundred chance of a crash,” Van Der Leeuw revealed. “I was very nervous seeing Stephen playing on stage and a lot of coders here in the Amsterdam office watching live-stream were also really, really nervous. But we made it through.”
Killzone: Shadow Fall is expected to be a PlayStation 4 launch title.
