Halo 2600 is an action-adventure video game developed for the Atari 2600 video game console, inspired by the Halo series of video games. Halo 2600 was written by Ed Fries, former vice president of game publishing at Microsoft, who was involved in Microsoft's acquisition of Halo developers Bungie Studios. Fries decided to create a version of Halo for the Atari 2600 after being inspired by a book called Racing the Beam: The Atari Video Computer System by Ian Bogost and Nick Montfort. The Atari 2600 had such limited RAM, only 128 bytes, that drawing Master Chief was difficult, and creating a game with other characters was even more so. Fries later stated that making the game taught him that constraint is sometimes a fuel for creativity.

Super 3D Noah's Ark is an unlicensed Christian-themed video game for the Super Nintendo Entertainment System and DOS. It was released by the biblical video game producer Wisdom Tree in 1994, and was the only commercially released SNES game in the U.S. that was not officially sanctioned by Nintendo. In order to bypass the Super Nintendo's lockout chip, Wisdom Tree devised a pass-through system similar to the Game Genie, where the player had to insert an officially licensed SNES game into the cartridge slot on top of the Super 3D Noah's Ark cartridge. Despite its name, it is unrelated to Konami's official Noah's Ark game for the Nintendo Entertainment System. In January 2014, the game was re-released for the SNES, initially available only by private email orders, but later through Piko Interactive's website. The game was also updated for the 20th Anniversary Edition and released at itch.io on May 26, 2014 for Windows, Mac OS X, and Linux. The game plays similarly to Wolfenstein 3D, but the graphics were changed to reflect a non-violent theme. Instead of killing Nazi soldiers in a castle, the player takes the part of Noah, wandering the Ark, using a slingshot to shoot sleep-inducing food at angry attacking animals, mostly goats, in order to render them unconscious. The animals behave differently: goats, the most common enemy, will only kick Noah, while the other animals such as sheep, ostriches, antelopes and oxen will shoot spittle at him from a distance. Goats are also unable to open doors, which the other animals can do. The gameplay is aimed at younger children. Noah's Ark includes secret passages, food, weapons and extra lives. There are secret levels, and shortcut levels as well. The player eventually comes across larger and more powerful slingshots, and flings coconuts and watermelon at the larger boss-like animals, such as Ernie the Elephant and Carl the Camel.

Action 52 is an unlicensed multicart video game compilation developed by Active Enterprises for the Nintendo Entertainment System. The NES version was released in 1992. The multicart consists of 52 games in a variety of genres, mostly scrolling shooters and platformers. The "featured" game is The Cheetahmen, which was part of Active's failed attempt to create a franchise similar to the Teenage Mutant Ninja Turtles. The NES version of Action 52 sold poorly and became infamous among gamers for the poor quality and functionality of its games; it is often considered to be one of the worst video games of all time.
