Scuba Diver is a game released for the Atari 2600, typically associated with Zellers, a Canadian chain of discount stores that produced unlicensed games for the console in the early 1980s. Players control a diver exploring the ocean depths, facing various challenges and hazards. As an early example of underwater adventure games, Scuba Diver fits within a niche genre of the era. Although not widely known, it reflects the unique market of third-party games that flourished for the Atari 2600.
