Special Criminal Investigation is quite a ‘special’ game. It is part of the Chase HQ series and was released on cartridge only, for the Commodore 64 at least, by Ocean Software in the UK.
SCI was also released late in the Commodore 64‘s lifetime (in 1990 to be precise), so benefited from coders knowing advanced programming techniques that could push the beige bread bin further than it had ever been pushed before.
And the result is a fast-paced, visually-impressive, and highly playable racing game. Sorry, chasing game… A conversion of the Taito arcade game, sometimes known as simply S.C.I. or Chase HQ 2: Special Criminal Investigation.
