“Call of Duty: Zombies” developer Jason Blundell has opened up on what it was like creating the “Zombies” mode that ultimately paved the way to the success of the “Call of Duty” franchise. 

Speaking with Gamespot, Blundell revealed how he and his team did not have funding to realize what they have conceptualized at lunchtime back when they were thinking of a mode for “Call of Duty: World at War.”

“’World at War’ is where ‘Zombies’ was first created. It was made out of those little bits at lunchtime. It's literally made from the things from World at War. There was no speaking in the first one because there was no budget. There were no assets. That's why there's no VO. People always forget that,” Blundell said. 

Blundell, who is a longtime developer at Treyarch and currently the senior executive producer of the company, added that they neither had funding nor support to really work on the "Zombies” mode efficiently, and they only managed to release something very basic, which fortunately caught the attention of the franchise’s fans.

It did not take long until the “Zombies” mode achieved unprecedented success, and Blundell said it was the fans who made all of the company’s efforts all worth it.

"It [expanded] because of the fans. It sounds corny, but it's the reality of what happened,” Blundell said.

Blundell’s interview was published just a day before “Call of Duty: Infinite Warfare” developer Brian Horton talked about the upcoming game to GamingBolt

According to Horton, who is a part of Infinity Ward, the upcoming “Infinite Warfare” is going to be centered on a band of brothers.

“Our focus was to try and tell a character-driven story of a band of brothers; so Lt. Reyes is surrounded by a cast of fully fleshed out squad mates of which make up the fighting force that has to defeat this settlement defense front,” Horton stated. 

“So your characters are going to help you in an A.I. capacity as well as further our narrative throughout the game. So they are going to play pivotal roles all throughout the story mode itself,” he added.

Meanwhile, it was reported back in May that the “Zombies” mode of the upcoming game by Infinity Ward and Activision will be original in terms of storyline, gameplay and mechanics, according to Polygon

“Call of Duty: Infinite Warfare” is set for release on Nov. 4, 2016 on PlayStation 4, Xbox One and PC.
