He is a film director responsible for numerous zombie-themed films who has travelled to Harran to acquire footage for his movies, sheltering with the survivor residing within Jaffar's Wheelstation.
When approached by Kyle Crane, he asks to film Crane as he kills infected in specific ways.
Irwin:"Crane?! You're Crane, right?! Kyle Crane?" Crane:"Yeah?" Irwin:"Irwin Snowberg. Movie director. I make the Zombie-annihilation movie series. You've probably seen them." Crane:"No." Irwin:"They're thought-provoking meditations about people very much like yourself, who have to kill butt-loads of zombies, for various reasons. The details really aren't important. What is important is production cost. Makeup is a major factor. I'm talking head-rot, arms falling off, guts hanging out. And when you blow 'em apart with guns - those squibs cost like crazy." Crane:"So you've come to Harran." Irwin:"It's a tragedy, of course. But there's a fortune in special effects shambling through the streets, just waiting to have their heads blown off for my next movie, Zombie-annihilation IV: Dying Lunch! All I need is a gun-not, who can drop them in spectacular numbers, and I am told you're just such a man."
