One of their earliest arcade hits was the 1989rail shooterDynamite Duke, one of the first to feature close combat with long-range shooting. A year later, Seibu Kaihatsu became best known for their 1990 vertical-scrolling shoot 'em up arcade game Raiden, which was successful enough to earn several sequels and spin-offs in its series of titles. In 1991, a development department known as Rise Corporation(株式会社ライズ?) was spun from Seibu Kaihatsu. During the late '80s, Fabtek bought the rights to internationally distribute Seibu Kaihatsu's arcade titles outside of Japan.
In 1999, its arcade division vanished and its official website shut down. It was also rumored that they filed for bankruptcy; in fact, Seibu Kaihatsu temporarily disbanded itself. Therefore, Fabtek's international distribution rights expired while closing its business. During the same year, they established Mahjong Cats(開発部門 キャッツ?), right before the dissolution of their relationship with adult video game developers h.m.p. and Mink to develop adult mahjong video arcade games. In 2005, the development staff left Seibu Kaihatsu to apply at MOSS, then bought the development rights to the Raiden franchise from Seibu Kaihatsu to develop Raiden III and Raiden IV in order to keep the franchise's fanbase hyped with Seibu Kaihatsu assisting them.
