Abadox (アバドックス, Abadokkusu?) is a video game for the NES, subtitled The Deadly Inner War. It is a side-scrolling shoot 'em up in the vein of Gradius and R-Type. The game is notable for its unique visual design, as the game takes place inside the intestinal tract of a giant alien organism. Abadox is also known to be difficult, since it takes one hit from an enemy projectile to be killed .[citation needed] In Abadox, if a player is killed, one must restart from a checkpoint passed before death.

Action 52 is the name of two unlicensed multicart video game compilations released by Active Enterprises. Each of the two cartridges consist of 52 individual and original video games. The first was released in September 1991 for the Nintendo Entertainment System video game console, with a second released in May 1993 for the Sega Genesis (a Super Nintendo Entertainment System version was advertised in some magazines, but never released). It initially retailed for the comparatively high price of US$199 (or "less than $4 for each game"), and became notorious among gamers for the abysmal quality and functionality of its games. Many video game collectors value Action 52 for its notoriety and rarity. The boxes state that the cartridges contain "52 'new and original' exciting games". The games cover a variety of genres, although the most common are scrolling shooters and platform games. Among the games is The Cheetahmen, Active's attempt at creating a franchise similar to the Teenage Mutant Ninja Turtles.

Master Takahashi's Adventure Island IV is the fourth and final Adventure Island game released for the Famicom. It bears the distinction of being the final official Family Computer game in Japan and was never officially released for the international market. Unlike previous entries in the Adventure Island series, Bōken Jima IV plays less like a straight platformer and more of an action/adventure platformer, similar to the later Wonder Boy games.
