Coming in June from IDW, the new series will be supervised by "X-Files" creator Chris Carter, seeing Mulder and Scully's anonymous suburban lives -- together -- disrupted when they learn that someone is preying on everyone involved with the X-Files.
The new series will have scripts by "The Great Pacific" writer Joe Harris featuring art from Michael Walsh and colorist Jordie Bellaire, but it sounds like it'll be Carter's show all the way (the press release calls out Whedon's involvement in "Angel: After the Fall" although that's kind of a shaky comparison since some of that stuff's been straight-up ignored since the move back to Dark Horse).
The ninth season finale -- which aired back in 2002 -- featured Scully helping free an imprisoned Mulder while the cigarette smoking man was seemingly killed by the ubiquitous black helicopters. That wasn't the last we saw of Mulder and Scully of course, with 2008's "X-Files: I Want to Believe" uniting the characters for one more case that involved a defrocked priest and... a "Frankenstein"-esque plot, if I recall.
From the official synopsis:
In the opening story arc, “Believers,” readers will catch up with Dana Scully and Fox Mulder, living normal lives together under secret identities. However, a visit from an old friend threatens to rip them from suburban anonymity, as they learn that someone is preying upon everyone involved in THE X-FILES. Prepare to revisit familiar faces—some very unexpected, threats old and new, and an intriguing mystery designed to return the beloved franchise to its former glory!
The first issue of "The X-Files" ongoing kicks off the new arc, "Believers," on June 29th from IDW.
