Sucker Punch uses real-life extras to populate the city of Seattle in Infamous: Second Son – developers recruited 75 friends, family members and professionals over three days to sit in front of a complex camera installment, absolutely still, while the lenses strobed out layers of their faces. With friends like Sucker Punch, who needs seizure medication? Everyone, probably.
There's a visual breakdown of Sucker Punch's scanning process on Game Informer. Or, if you're patient, just buy an Xbox One later this year and sit really still in front of that always-on Kinect camera – and maybe you'll spot your own fine face in a next-gen crowd. (You probably won't. We hope.)
