Campaign director Jason Blundell reveals that there are many undiscovered secrets and easter eggs within the zombie modes going as far back as Call of Duty World at War.

Even though the Call of Duty franchise is a global sales juggernaut that is maintained by a handful of studios under Activision, Treyarch has managed to stand out from the rest – thanks in part to its unique Zombies mode. While a simple horde mode variant at first, the mode has taken on a life of its own, getting more and more attention through each game with deeper mechanics and lore. Easter eggs are also a major element, and as it turns out, the developers at Treyarch have managed to slip a good amount past players dating all the way back to the first appearance of the popular mode.

In a recent interview, Campaign Director and Director of Zombies (yes, that is an actual title), Jason Blundell, admitted that there are a good amount of secrets and easter eggs that have yet to be discovered by fans. Surprisingly, there are secrets that fans have missed all the way back to the original mode which debuted six years ago in Call of Duty: World at War as well. While many of the mechanical secrets have been unearthed by players, some of the more obtuse and hidden ones are still waiting to be discovered.

According to Blundell, there's still plenty left for fans to locate.

"I was having a chat with someone and they were saying 'we've found them all!' and I went 'OK, well here's one then - have you looked at the bios for World at War?' That's now 6 years old, and there was a hidden message that was taking the first capital letter of every sentence in the bio, and it made a sentence. They'd already written it off and moved on - there is more of that kind of stuff throughout all the maps."

"Sometimes people go about it literally with Easter Eggs - in other words, I'm going to press X on this and I'm going to do that - and a lot of those have been discovered, because it's the most obvious part, and once you start taking things apart they can look at it and go 'oh that's how you do it'. The Easter Eggs left on some of those earlier ones are now more spiritual-based ones, or kind of clues to things."

Easter eggs appear to be a big part of the design process at Treyarch, as each one is broken down into four classifications: Light, Medium, Heavy, and Impossible. The developers have even placed bets around the office as to how long it will take players to find specific secrets. Bludell even tipped players off half a year ago to the existence of many challenging easter eggs within the game, which should keep players busy for quite a while.

There's plenty of history to go back through for Zombie fans, though just recently, the Eclipse DLC pack arrived for Call of Duty: Black Ops III players on the PlayStation 4. In addition to four new multiplayer maps, the pack also introduced the next story piece for Zombies and it follows the events of Der Eisendrache. The latest map is known as Zetsubou No Shima, and it takes the original cast of characters to an island in the Pacific during World War II. Players will come across a secret lab which had been home to numerous (probably illegal) experiments, and no doubt contains a wealth of secrets to be discovered.
