LEGO released the X-Files set number 21369, containing 1,478 pieces and eight minifigures including Fox Mulder, Dana Scully, Walter Skinner, Mr. X, Alex Krycek, Carl Busch, The Flukeman, and a grey alien [1, 2]. The set retails for $200 in the U.S. and is priced at £179.99 in the UK, €199.99 in the Eurozone, CAD$269.99 in Canada, and AU$329.99 in Australia [1].

The set features a cutaway underground lab filled with Easter eggs, a forest scene with a UFO supported on a clear brick, and a detailed recreation of Mulder's office, including pencils embedded in the ceiling as a nod to fans [1, 2, 3]. A standout element is The Flukeman minifigure, representing the monster-of-the-week from season two of the original show [2, 3].

LEGO released a live-action promotional video on July 21 starring Gillian Anderson as Dana Scully interacting with the set. In the video, Anderson snaps on latex gloves and picks up a David Duchovny minifigure, joking, "I don't remember you being so small" [1, 2, 3].

A smaller "Gift With Purchase" set featuring the Scully's Lab minifigure will be available while stocks last with the main set purchase [1, 3].

The X-Files set became available to LEGO Insiders starting August 1 and launched for the general public on August 4 [1, 3]. On August 14, the R-rated Director’s Cut of The X-Files: I Want to Believe will be released on Hulu [1].
