An executive from the development studio Sledgehammer Games, maker of 2014's "Call of Duty: Advanced Warfare," confirmed that the company is working on a new project.

Although the executive did not go into detail regarding the upcoming project, various sources assumed that it's for a new "Call of Duty" title.

Sledgehammer Games launched "Call of Duty: Advanced Warfare" in November of last year. The game, which featured the voices and likeness of veteran actors Troy Baker and Kevin Spacey, was a massive success and was even named as the top selling game in the U.S. in 2014.

Due to the success of the game and how Sledgehammer Games became an effective subsidiary of Activision, talks about a possible sequel, which is currently dubbed as "Call of Duty: Advanced Warfare 2," began to emerge.

Then, recently, Glen Schofield, the co-founder of Sledgehammer Games, fired off a couple of Tweets to talk about the studio's latest project, according to VG247.

"We're designing a new game so in design mode I do art," he tweeted. "That's how I think. Probably weird but it's my way of concentrating."

"Can't talk about the game but we listened and so I am so f*****g stoked about this one," he added.

Despite remaining tight-lipped on the matter, the fact that Schofield "listened" suggests that an "Advanced Warfare 2" might be in the works given how much fans of the first game have been asking to studio to develop a sequel.

Or, as noted by Gamespot, the upcoming game from the studio could be the discontinued third-person "Call of Duty" title that Sledgehammer Games was previously working on. According to the gaming news site, the studio scrapped the project after it was asked by Activision to help out Infinity Ward with the development of 2011's "Call of Duty: Modern Warfare 3."

Not much is known about the discontinued project but it was supposed to be set in Cambodia during the Vietnam War. Also, it has the potential to revolutionize the "Call of Duty" franchise through its third-person perspective.

But, if Sledgehammer really is working on a new "Call of Duty" game, whether it's "Advanced Warfare 2" or the third-person shooter, gamers will probably have to wait until 2017 to see it. After all, Activision just kicked off its three-year development cycle for the "Call of Duty" franchise with Sledgehammer Games' "Advanced Warfare" last year.

And since this year's entry, specifically "Black Ops 3," came from Treyarch, that means that new "Call of Duty" game that will arrive in 2016 will be handled by Infinity Ward.
