Gesaffelstein promoted the album with "mysterious" billboards and social media posts throughout November, with the album's cover art and title being shared on a billboard in Miami in December 2018. The website Dancing Astronaut stated that it was not clear from the billboard whether the entire billboard itself or the included picture of a "shattering black pane" was the cover art. The album's release was preceded by the release of three singles, "Reset", "Lost in the Fire", and "Blast Off". The first being released on 29 November 2018, the second being released on 11 January 2019, and the third being released on 1 March 2019.
Upon release, Hyperion received mixed reviews. In a positive review, Kat Bein from Billboard stated Hyperion as being good, complimenting the album cohesion and experimental tracklist.Pitchfork's Larry Fitzmaurice's praise was muted, rating the album a 5.0 on a 10-point scale. Fitzmaurice called Lévy's production a "budget-level attempt to replicate ... other artists", ultimately calling Lévy an artist who has not defined himself, and stating, "that while he has consistency on his side, true artistic evolution remains out of Lévy's reach."NME's Luke Morgan Britton criticized the collaborations for not capturing unique qualities of guests and found the album "directionless".
