Worth the 25-minute watch
Call of Duty: World at War‘s zombie mode was an incredible addition to the industry. It was a fully featured mode that was actually included in the base package, and I played the first map for 100 hours, easy. I still play zombies to this day and haven’t gotten tired of it.
The presentation goes through the entire history of zombies mode, right from the very beginning, and how the entire concept was almost scrapped. It’s interesting to see Treyarch at the forefront here, as I consider it to be the best developer in the franchise’s history.
