Our favorite GTA 5 Collector's Edition easter egg is the GTA map. When held under UV/blacklight it reveals clues to locations of paranormal hotspots like bigfoot sightings, alien bases and UFO crash sites. If Mulder was a gamer, he'd be all over this shit...and Scully would be just another GTA widow.
Loads of the clues provide the locations for hidden spaceship parts that you can collect and create your own goddamn UFO!*
*sorta, it's more like a UFO-ish dune buggy that shoots frickin' lasers.
When held under a UV light...
This gamer actually found Bigfoot!
