one layer to save time and avoid redesigning tables when minor changes were required. Almered composed the music under general guidelines provided by Zetterberg using the Octalyser sound driver to set the mood for each table, while sampling instruments from sample CDs and multiple synthesizers. Zetterberg told Almered that he wanted to reflect a post-war scenario when composing music for the "X-ile Zone" table. Lundqvist coded the ball routine but proved difficult and took a year for him to program the routine. Despite receiving governmental startup support, however, Jansson stated that the scope of Obsession had grown too much during development and the team struggled to get the game working and ship it in time. Release Obsession was first showcased in a playable state at the 1994 Bristol Atari Show and initially slated for an October 1994 launch. The game was first released by Unique Development Sweden for the Atari STe on December 2, 1994. It was also distributed in France by Frontier Software. The title was later ported to the Amiga by UDS and released on June 1, 1995. A conversion for the Amiga 1200 featuring a new table and a multiball mechanic was planned but never released. According to Tord Jansson in a 2018 interview, work on Atari Falcon and PC port began after the release of the Amiga version but the latter version evolved into a new project with new tables and features titled Absolute Pinball, while the rights to the unreleased Falcon version were sold to a French company. Jansson also stated that Atari Corporation gave the team an Atari Jaguar development kit which he and Ulrik Lindahl, another programmer at Unique Development Sweden spent time with it and created a conversion of Obsession with only three out of the four tables to the Jaguar in a few days except the music and sound effects. However, UDS decided not to support the system due to its low sales and sent back the development kit to Atari Corp. Reception Obsession garnered critical acclaim from reviewers when it was released on the Atari STe. ST Reviews Tina Hackett praised the visual presentation of each table for pushing the limits of the STe hardware, sound, controls and addictive gameplay but criticized the lack of a multiball system and a double set of flippers on the tables. German magazine Atari Inside commended Unique Development Sweden for creating a "great" pinball
