Cyberfront bought the rights to the Infinity series after its previous developer, KID, closed down.
The game's writing was done by the group Run & Gun, while the sound production was handled by the band Milktub.
While the development team had originally planned to use a theme of "escape from an enclosed space" similarly to previous Infinity games, it was changed due to concerns of the size of the game's audience, and was seen as a reboot of the series.
