Hunt A Killer: The Cosmic Adventure Of Supernova

From BoardGameGeek:

After signing up for a membership to The Official Supernova Fan Club, you are contacted by Gunny Graham, the reclusive series creator. For over a decade, he has been unsuccessful at contacting his twin sister, Halo. He believes she's still somewhere out there, alive, but in the clutches of The Void. He needs your help to find his sister before he loses her forever. In this all-in-one box, you'll receive evidence from Gunny Graham that will reveal the whereabouts of his sister. Solve puzzles, examine clues, and decode mysterious dark symbols of The Void. Translate the alien language, "Aquarian," pore over vintage documents, and sort through superhero merchandise to find Gunny's twin sister. Your choices matter! This game has two different endings, and you determine the outcome of the story. Difficulty: 3/5 - Medium Note: In order to play this game, you will need a Hunt a Killer account so they may send you an epilogue. -description from publisher's website
