Sin City gaat gebruik maken van Unreal engine 3
"The Unreal Engine is one of the most technically advanced engines on the market and is a perfect fit for our Sin City video games. The engine has powered several of the best-selling games of all time and I am very glad we have the opportunity to arm our developers with such a world-class product."
Mark Rein, vice-president bij Epic Games, zag ook wel brood in een Sin City-game.
"We're extremely excited to be working with Red Mile. We have been Frank Miller / Sin City fans for a long time and are pleased that our technology will be a key factor, and we're confident that they’re going to make a great game with it."
