IK+ Prototypes Emerge for Atari ST and Amiga
Games That Werent has recently unearthed and preserved a collection of early prototypes and graphical assets for Archer Maclean's seminal fighting game, IK+ (International Karate Plus), across both the Atari ST and Amiga platforms. It's a fascinating glimpse into the creative process of Archer Maclean, a true luminary of British computing, to see a blood dripping effect in an early Atari ST build of IK+ that never made it to the final, more family-friendly release.
The discovery includes two distinct prototype builds for the Atari ST. The earlier of these lacks music and shows unrefined gameplay, with the player starting as a red belt despite the white belt designation and bonus games appearing after just one fight. Notably, graphical elements like the bombs are missing from this version, suggesting a very early stage of development.
The second Atari ST prototype is much closer to the retail release, featuring a proper loader and the game's iconic music. However, it still retains that initial blood effect, which was ultimately removed. These subtle differences provide a window into the iterative design choices made during the game's creation, showing how features were added, refined, or discarded.
Unearthing Archer Maclean's Vision
Beyond the Atari ST builds, the preservation effort also includes an Amiga version that requires a specific file load to boot, presenting with some graphical and sound glitches. This build appears to be near completion, offering another perspective on the game's cross-platform development. The real story here is not just the existence of these builds, but what they reveal about the iterative design process, showing how even a classic like IK+ evolved from more raw, experimental beginnings.
Many of the disks contained the original sound samples used in the game, some of which may not have made the final cut. Perhaps even more compelling are the numerous graphical assets, stored as NEOChrome files. These include sprites that were never used, particularly for background animations, alongside various logo and background tests. There are also what appear to be early video titles and other test drawings by Maclean himself, including shirt designs featuring the IK+ logo.
A Glimpse into the Development Process
This preservation work, made possible by Chris Wilkins of Fusion Retro Books, who loaned Archer Maclean's original development disks, and Alan Hammerton, who provided crucial hardware assistance, is a vital contribution to our understanding of period software development. It allows us to appreciate the detailed work that went into titles like IK+, a game that captivated many a bedroom coder and player in the mid-1980s, just before the summer of 1986 saw the release of the Amiga 500 in the UK.
The availability of these prototypes and assets allows enthusiasts and historians to explore the creative decisions and technical challenges faced by developers like Maclean. It is a fitting tribute to Archer Maclean, who sadly passed in December 2022, ensuring that his unseen work continues to inform and inspire those who cherish the golden age of British and European microcomputing.
