The new X-FILES trailer isn’t giving much away about the upcoming series but it certainly suggests they’ll be high drama with explosions, military involvement and some pretty intense exchanges between agents Mulder and Scully.

The new trailer was released by Fox on Monday (28th September) only weeks before Fox plans to debut the first episode of the six-part miniseries at New York Comic-Con on October 10th. The trailer, which is the first full-length one for the series, was shown in two parts in the ad breaks in Gotham and Minority Report on Monday night.

The first part of the trailer starts with a voiceover in which Mulder explains how in 2002, after the original series ended, his investigation had ceased but his obsession with the unknown had not. It appears another case comes up as a helicopter and what look suspiciously like government agents are on his lawn. Scenes of Washington D.C. cut in. The voiceover continues, with Mulder explaining how he cannot “do this alone” and Scully is shown receiving a call from Mulder.

The second part also features a voice over with Mulder stating that "They police us, spy on us, tell us that makes us safer” as images of CCTV cameras and drones flash on screen. Further cut-ins include scenes of the military investigating a site in the desert and Scully warning Mulder of the danger he is in. 

As The Verge reports, there may be a few hints hidden within the trailer including, in the closing seconds, a smoking cigarette suggesting the return of The Smoking Man. The Smoking Man, a member of a shadowy and sinister government body, was Mulder’s arch-nemesis throughout the majority of the original series. Although The Smoking Man was killed in the series’ ninth season, he had previously regenerated so there’s the possibility that he could return. 

The upcoming mini-series, due to be broadcast on Fox in January, sees the return of Mulder and Scully after 13 years off the small screen. The cult classic was originally broadcast on Fox between 1993 and 2002. David Duchovny and Gillian Anderson, who played Fox Mulder and Dana Scully respectively, have previously reprised their roles in two feature film spin-offs of the series: The X-Files (1998) and The X-Files: I Want to Believe (2008).
