S.C.I. - Special Criminal Investigation © 1989 Taito corporation.
A direct sequel to 1988's Chase H.Q., S.C.I. once again puts the player in charge of an unmarked police car - this time a red Nissan 300ZX [Z32] T-Top turbo - in which the player must chase and capture a criminal mastermind before the time limit expires. Graphically, S.C.I. is very similar to its predecessor, although there are slight improvements with both a better use of color and the introduction of some weather effects; such as the rainy thunderstorm on the stages #1 and #4. Unlike the first game, the player is armed with a gun; this is used to take out criminals and roadblocks as the player races against the time limit, and also to capture the criminal mastermind and make an arrest before the time limit expires.
This game was available in at least 3 different dedicated cabinets, plus it was also sold as a conversion kit for "Chase H.Q".
* The sitdown version is a strange plastic monstrosity with a huge monitor. This may have been a Japan only release, as the cabinet looks very similar to the popular Japanese cabinet style.
* The standup versions are all very solid wooden affairs, covered with full painted sideart (very few games still used painted sideart in the late eighties).
All versions use Happ Controls force feedback steering wheels (the ones that can spin all the way around), a high low shifter (different versions had this on different sides), and a single pedal (gas, but some versions featured also a brake pedal).
