Jim Walls is an American video game designer. He is notable for having designed the successful Police Quest series of adventure games for Sierra On-Line. After working as a California Highway Patrol officer from 1971 to 1986, Walls met Sierra president Ken Williams, who wished to create an adventure game in the police procedural genre. Walls, though inexperienced with computers, offered his policing experience. During his career at Sierra, Walls designed the first three Police Quest entries and Codename: ICEMAN. After leaving Sierra in the early 1990s, Walls joined several other game developers, including Tsunami Media in 1992 and Westwood Studios in 1996, before retiring in 2003. In 2013, Walls planned to develop Precinct, a spiritual successor to Police Quest, but the crowdfunding campaign failed.
