It all ties into what has work he did before he joined the game industry. In C&VG Magazine he says:
Before getting his first gaming job, making wrestling titles for Human Entertainment, he was working as an undertaker, which he hated. Being an undertaker made him think about how he portrays death in games. “I’m probably one of the few game developers that’s actually seen a dead body! I’ve always wanted people to experience death in my games in a powerful way.”
When asked if a sequel to Killer 7 will ever happen, he stated he’d love to make another Killer game, but that it doesn’t seem that that’s going to happen. To quote:
“Unfortunately, Capcom own the rights, so it’ll probably never happen.”
