ZACK is the ZAp-em-up Construction Kit, an unfinished game creator software for the CPC. A unique and very promising package for people who wanted to create professional quality games easily. Written by Richard Wilson (Executioner) in 1993. According to the author himself: Everything got finished except the sound/FX and completed game loader/multi-load code.
