Secret Quest

The player controls a hero trying to stop several alien space station attacks. He is dressed in a space suit fighting aliens released from the space stations. He is trying to defuse a bomb set by the aliens, and detonate bombs in the space stations using codes.

The game was inspired by Nintendo's The Legend Of Zelda (1986) for the Nintendo Entertainment System, with the final space-themed concept developed and programmed by Steve DeFrisco. Chris DeFrisco was hired to complete the artwork. A save-game mechanic was incorporated due to the design concept of having many locations in an adventure-style format. The development team faced data-size issues when trying to fit the game onto the cartridge ROM.

According to Vintage Games, the game was created as a final attempt to prove the 1977 console could compete with more modern hardware. The cartridge is expanded with 256 bytes of RAM and 16 kilobytes of ROM.

NexGam believed the graphics were simple yet respectable. The A.V. Club thought the title was surprising and abstract in the wake of the Atari 2600's final days. Classic Home Video Games called the game ambitious, almost to a fault. Classic Videogame Hardware Genius Guide described it as a "final swan-song" and a way of squeezing the last money out of the console.

Secret Quest was included in the Atari FlashBack 2 and subsequent consoles in the series with the exception of the FlashBack 4. In 2022, it was included as part of the Atari 50: The Anniversary Celebration compilation for Nintendo Switch, PlayStation 4, Steam, and Xbox One.
