George A. Romero, the legendary director behind the Living Dead series of movies, has passed away. The veteran – who appeared as a character in Call of Duty: Black Ops – is considered by many to be the father of the zombie genre, and his enormous influence can be felt all over the video game industry. It’s not surprising, then, that developers like Neil Druckmann and Hideo Kojima have been swift to pay tribute to the filmmaker’s legacy.

Practically every horror game from Resident Evil to The Last of Us owes a portion of its success to Romero, and the likes of Night of the Living Dead and Dawn of the Dead remain classics even today.
