Cats aka Paws

Written and reviewed in Sinclair User, the game was withdrawn due to copyright infringement of the musical Cats by Andrew Lloyd-Webber. The game was slightly modified to get over this hurdle and was released as Paws.

Moon Patrol Moon Patrol

After announcing that they were bringing out some of their classic arcade games for the Spectrum, only four Atarisoft games made it to the shops:- Pacman, Pole Position, Ms Pacman and Galaxians. Although completely written, Moon Patrol for some reason was never published!

The Eye Of The Moon

In the Lords Of Midnight manual, the sequels Doomdark's Revenge and The Eye Of The Moon are mentioned, see left-hand image. When Doomdark's Revenge was released, The Eye Of The Moon was mentioned again on the first page of the manual. After Beyond were taken over by British Telecom, the third installment of the trilogy was put on the backburner and never saw the light of day although some work towards the game must have been done. A third installment of the saga did eventually arise, in the form of The Lords Of Midnight: The Citadel for the PC.

Superman Superman - The Game

Beyond Software has first refusal on games developed by First Star Software, with Superman being advertised on their Five Boys advert. The game was originally advertised for the C64, Atari 400/800/XL, Amstrad and Spectrum, however only the C64 version was eventually published by Beyond. It was around this time that Beyond was bought out by British Telecom and after lengthy delays, Superman was eventually published by Prism Leisure.

Star Trek Star Trek - The Rebel Universe

Beyond Software assigned Mike Singleton to development a game based on the Star Trek franchise for the ZX Spectrum and C64 8 bit computers. Regular previews and news items appeared in various Spectrum magazines throughout 1986. Unfortunately, due to other commitments, the ZX Spectrum version was never released. With the demise of the Beyond label, it was left to Firebird to publish the C64 version. Star Trek was the most famous holder of the Scooby award, for games which fall way behind schedule!

Scooby Doo In The Castle Mystery

After a few months of advertising and some preview screens being published in Crash, it became apparent that the original game design (A Dragon's Lair type game) couldn't be achieved on the ZX Spectrum. In order to get a game in the shops with the Scooby Doo licence, the work was given to Gargoyle and a platform game was subsequently published towards the end of 1986.

The entire trilogy "The Siege Of Earth" was advertised in the advert below, but only Marsport was ever released. A feature on Fornax appeared on page 112 of the Novermber 1985 issue of Sinclair User. The story was as described below:-

Marsport: The year: 2494. Earth is under seige by the ant-like Sept. The huge force-field protecting Earth is beginning to fade, and the original plans must be retrieved from the great city of Marsport, now occupied by the alien Sept... Commander John Marsh of the Terran Liberation Forces battles against the Sept Warlords and the robotic defences of M-Central in one last effort to reach the plans inside the Marsport City Computers.

Fornax: Fornax, the fire planet, is a world populated by Sept of the scientific caste, who are studying the ancient Star Lord civilisation with the help of mutated humans. The Terran Resistance must outwit the Sept brains and solve the enigma of the Star Lords in order to uncover the greatest secret of all - the location of the Sept Imperial planet, Gath.

Gath: The story was never written as far as I know.

Bandersnatch & Psyclapse

Bandersnatch was Imagine's new "mega-game" costing £30 when completed, which was to include a hardware add-on. The game was far from being complete when the company went bust. A new company called Finchspeed was set-up after Imagine folded which sold the rights to the game to Sinclair Research Ltd. A complete working version was then developed for the QL before Finchspeed folded. The directors Dave Lawson and Ian Heatherington then formed Psygnosis and the game was later released for the Amiga/ST as Brataccas.

Masterspy Masterspy

Masterspy was a game developed by Albert Ball of Jumping Jack and Rapscallion fame. Due to delays in completing Masterspy, Albert thought it wasn't worth releasing due to more sophisticated games becoming available. Luckily Albert kept a copy of Masterspy on tape, which has been successfully preserved with the assistance of Josť Luis Soler Hidalgo.

I recently wrote an email to Jon and this is the reply I got:- "No, I'm afraid the early stages of Starship were on microdrive but when I tried to look at it a couple of years later I found they couldn't be read". Shame! In the August 1988 issue of Your Sinclair, the following article was published about Starship just after it had been abandoned. I have also found this scan of an announcement of the formation of Outlaw, with Starship being their first game!

Gyruss Gyruss - Prototype

Back in 1984, Parker Brothers announced that they were going to release conversions of several arcade games including Gyruss and Star Wars as interface 2 cartridges priced at £19.95. The releases were shelved however, when the interface 2 sold in poor numbers.

A feature appeared in issue 71 of Sinclair User which reported that the game was being programmed by Imagitec for Piranha. The project was probably shelved along with Judge Death (see below) when Piranha went bust.

Judge Death

Judge Death was first previewed in the November 1987 issue of Crash plus a few spots in Sinclair User. Then in the December issue it was advertised along with a special edition of the Judge Anderson comic. The game was due to be completed ready for a review in the January issue, but the game was never completed because the publisher Piranha went bust.

Miner Willy Meets The Taxman aka The Megatree

In an interview in the March 1984 issue of Personal Computer Games, it was reported that "After another skiing trip Matthew expects to start thinking about a follow-up to Jet Set Willy - perhaps to be called Willy Meets the Taxman.". This may have been a joke on the spur of the moment, but nothing was ever seen of this proposed follow up to Jet Set Willy. A sequel was later released which was a souped up version of the original with extra rooms, but this was not written by the man himself!

The development disks for The Megatree were recently won by Retro Gamer magazine, a feature covering the contents of the disk appeared in issue 5 of Retro Gamer.

Underwurlde, the second game in the Sabreman series had three seperate exits from the castle. Each exit had a different congratulations screen naming another adventure in the Sabreman saga. Exit one named Knight Lore which was released at the same time as Underwurlde. Exit two named Pentagram which was released in June 1986. The third exit named Mire Mare which was never published. The reasons for this have only just been made public, see the interview at the Ultimate Appreciation website, linked below.

Block Wars 3000 AD

This quote, direct from the author explains why the game was never released:- "Just to keep your records straight I'm sad to say Block War 3000 AD never made it to the public, it was proving too much for the memory available as it was supposed to be an 8 player game! Shame because it looked brilliant and I had lots and lots of pre orders for it, I think it would have been a big seller as it was set around judge dread etc."

World Cup Carnival World Cup Football World Cup Carnival

Quite a stir was caused when US Gold released the old Artic game World Cup Football under the new name of World Cup Carnival at twice the price of the original. The explanation given at the time was that the game developed to coincide with the World Cup was so bad it couldn't be released. Since there was not enough time to develop a new game, the old Artic game was re-released under the new name. If this is the case, then there is a completed unreleased version of World Cup Carnival out there somewhere.
