Lust From Beyond: Scarlet is a game released in October 2020, and the second of two free-to-play prequel stories for Lust from Beyond. The first free-to-play prequel was Lust from Beyond: Prologue. It is the third entry over-all in the "Lust-verse."
Scarlet was delayed due to a hidden secret room containing topless polaroids of one of the voice actresses. Despite the consent of the actress involved, this violated the terms and conditions of Steam (through which Scarlet was distributed) as the site does not allow real photos to be used in games on the platform. The photos were eventually altered with a filter before general release, to pass Steam's certification process.
