In 2014, the eleventh mainline Call of Duty game titled Advanced Warfare was released with a focus on futuristic gameplay, featuring a couple of celebrities. While garnering generally positive reviews, Advanced Warfare was never followed up with a sequel - now we know why.
According to a former Call of Duty developer, the franchise almost saw the addition of an Advanced Warfare sequel. Brett Robbins made this revelation during a recent interview with MinnMax where he stated that the follow-up was in the works in 2017 at Sledgehammer Games, the studio responsible for the original title.
Robbins, who was a Senior Creative Director at Sledgehammer Games, further revealed that the title had an early prototype before the project was canceled in favor of Call of Duty: World War 2. In his words, "We had some early prototypes and might have even done a demo level of it, and then WW2 came back and felt like a better opportunity. I'm glad we did, I am glad we switched gears, but Advanced Warfare 2 would have been awesome."
Robbins's sentiment was shared by the rest of his team as, according to him, a lot of people on the team were interested in developing the World War 2-inspired title which they felt had more story and was "a bit more exciting and different."
