Mercenary: The Second City is an add-on for the classic game Mercenary that gives the player a new environment and new missions to solve. It was first released for the ZX Spectrum in 1988.
Paul Woakes‘ classic open-world cockpit exploration game, Mercenary, was ported to the 48K ZX Spectrum by David Aubrey-Jones and published by Novagen Software in 1987.
The Galaxian conversion for the ColecoVision was first released in 1984 by Atarisoft, and it is a decent port of the classic 1979 arcade game from Namco. A secret message in the game credits James D. Eisenstein for writing the graphics and program (he also dedicates the game to his then wife/girlfriend, Jeneane).
Super Fantasy Zone is a conversion of the 1986 Sega arcade game, Fantasy Zone, re-programmed by Sunsoft and published by Sega in 1992. The game was initially only released in Japan and Europe, but North America did finally receive an official release of the game via Virtual Console in 2008. The game is also included on the Sega Genesis Mini.
Duke Nukem on the Game Boy Color is a conversion of the classic MS-DOS game and was developed by Australian company Torus Games and published by GT Interactive in 1999. It is based on both Duke Nukem and Duke Nukem II although it plays more like the second game than the first.
Palace Software‘s Cauldron II: The Pumpkin Strikes Back is the sequel to the cult hit, Cauldron, released in 1985. Cauldron II was first released for the Commodore 64 in 1986 and this is a conversion of that game. It features gameplay that is quite different to the original Cauldron, although it is essentially still a platform game at its core.
The ZX Spectrum version of Palace Software‘s The Evil Dead video game was never released as a stand-alone title, although it was given away as a freebie on the b-side of the cassette for the ZX Spectrum version of Cauldron. Probably because Palace realised that no person in their right mind would pay money for a game this bad.
