Later games were based on the company's Freescape rendering engine. Developed in-house, Freescape is considered to be one of the first proprietary 3D engines to be used in computer games, although the engine was not used commercially outside of Incentive's own titles. The project was originally thought to be so ambitious that according to Ian Andrew, the company struggled to recruit programmers for the project, with many believing that it could not be achieved.
Paul Gregory (graphics artist for Major Developments, Incentive's in-house design team) mentions  that Freescape was developed by Chris Andrew starting in September 1986 on an Amstrad CPC, as it was the most suitable development system with 128K memory and had adequate power to run 3D environments. Due to the engine's success, it was later ported to all the dominant systems of the era: the ZX Spectrum, the IBM PC, the Commodore 64, Commodore Amiga and Atari ST. Freescape development ended in 1992 with the release of 3D Construction Kit II.
