In an interview with Nintendo Player, Jason Bakutis, who designed the game's monster models and prosthetics, claimed that Viridis Corporation intended to commission English neo-psychedelia band Echo & the Bunnymen to compose the game's soundtrack. However, these plans fell through for unknown reasons. Ultimately, the soundtrack was provided by Mark Andrade, who also played Gaspra in the opening FMV; however, most of his compositions were omitted from the final game, which instead uses ambient environmental noises for the majority of gameplay.
