'Call of Duty' returned to its World War II roots for its latest game because they wanted to "tell stories that haven't been told in a while".

Michael Condry, the co-founder and studio head at video game developer Sledgehammer Games, who worked on the game series, believes the decision to release 'Call of Duty: WWII' was part of taking a "different opportunity".

He said: "These are big games, and they take a big team a lot of time to develop these really robust experiences. So three years in development. If you think about when that was - around 2014 - there hadn't been a renewed interest in World War II in film just yet. We didn't know about 'Dunkirk' or 'Allied' or 'Hacksaw Ridge'.

"Over the past few years, there's been this resurgence of telling these stories that hadn't been told in awhile. Three years ago we sat down and talked about the opportunity to go back to World War II after nearly a decade. It was coming off of Advanced Warfare, and we could have easily have done Advanced Warfare 2, but we saw a different opportunity.

"I think it comes down to wanting to tell stories that haven't been told in a while. We experienced that with Advanced Warfare as well. When we first started development on Advanced Warfare, the sort of near-future zeitgeist, if you will, hadn't really blown up yet. By the time we shipped that game, there was Elysium, Edge of Tomorrow, and a bunch of films all about the near-future."

And Condry also revealed why they chose to open the game up with scenes from Normandy.

He added to Inverse Entertainment: "Because we were focusing on the European Theater of the War, we felt like we needed to have our take on Normandy. That was really where it all began, at least for America, so that was important to us. That battle is just iconic. And even though it's been done before, we wanted to tell it in a Call of Duty way."
