Fox announced the limited six-episode "event" of X-Files on 24 March.
Fox executives Dana Walden and Gary Newman said in a statement: "The X-Files was not only a seminal show for both the studio and the network, it was a worldwide phenomenon that shaped pop culture—yet remained a true gem for the legions of fans who embraced it from the beginning.
"We're ecstatic to give them the next thrilling chapter of Mulder and Scully they've been waiting for."
X-Files lead actress Gillian Anderson tweeted the confirmation as well saying: "Mulder, it's me."
Speaking of the new X-Files' episodes, Chris Carter, the original creator of The X-Files who will also be leading the new production told The Daily Beast: "Every day I turn on the radio in the morning, I hear an X-Files story, or I pick up the paper and I see an X-Files story. So yes, the Mulder and Scully in my head are always switched on.
"David and Gillian wanted to do it. It was kind of the perfect timing for everyone involved. We all had a space in which to do it, we all had a desire to tell these stories, and, as I said in the press release, I think the world's gotten that much stranger in the last 13 years.
"For me, it's an opportunity as a storyteller to take advantage of that. Everyone wanted to do it, and the negotiations actually began in November, and were finalized yesterday. I'd say that it was simply a matter of everyone agreeing to the ground rules."
The X-Files ran over 200 episodes over nine seasons from 1993 to 2002. Two feature films were also released in 1998 and 2002.
Production is set to begin in June 2015 and the show's airing date is yet to be determined.
