Chase H.Q. is a series of four racing arcade games that were released by Taito Corporation between 1988 and 2007; they focus on a pair of undercover policemen named Tony Gibson and Raymond Broady (also known as Mr. Driver), who the player has to help catch up with various criminals' cars and ram (or shoot, in the case of the second title) them until they are too damaged to keep going before a timer runs out. The series also begat two spin-offs, Crime City (1989) and Quiz H.Q. (1990) - and its first two titles were later released in a compilation for the Sega Saturn, Chase H.Q. Plus S.C.I. (1996).
- Chase H.Q. (1988): The inceptive title for this series ran on Taito's Z-System hardware, and saw Gibson and Broady driving a custom black Porsche (in fact, one of its sitdown cabinets was shaped like it); it also had a "Turbo" activator which, when pushed, accelerated their Porsche to an incredible speed for a few seconds (but only for a maximum of three times per stage so it had to be used wisely to catch the criminals before the timer ran out).
- S.C.I. - Special Criminal Investigation (1989): The second title in the series also ran on Taito's Z-System hardware, but this time it saw Gibson and Broady driving a red Nissan 300ZX T-Top Turbo; they were also armed with a gun which had to be used to take out criminals and roadblocks as they raced through the stages (for the World version, the female operative Nancy was also renamed to Halen, possibly after the rock band of Van Halen).
- Super Chase - Criminal Termination (1992): The third title in the series ran on Taito's Super Z-System hardware (which used a Motorola 68EC020 running at 20 MHz, a Motorola 68000 running at 16 MHz and an ES-5505 sound chip running at 15.23805 MHz, not like the original Z-System at all), and again saw Gibson and Broady driving their red Nissan 300ZX T-Top Turbo (but changed the view to first-person and relieved them of their gun).
- Chase H.Q. 2 (2007): The fourth title in the series ran on Taito's TX hardware and saw Gibson and Broady driving one of three new selectable cars.
- Crime City (1989): The first spin-off in the series was a Rolling Thunder-style run and gun game which ran on Taito's B-System hardware, and saw Gibson and Broady fighting against criminals on foot through six stages, each of which focused on a specific theme; they started each stage armed with a pistol, but would acquire extra weapons as they progressed (however, both the pistol and extra weapons only had a limited amount of shots).
- Quiz H.Q. (1990): The second spin-off in the series was a Japan-exclusive quiz game which ran upon Taito's F2 hardware, and saw the players (as two could play simultaneously) having to help Gibson and Broady catch up to criminals in the original game's Porsche by answering multiple-choice Japanese questions; as in Quiz Torimonochō, a knowledge of the three Japanese writing systems is essential for players who wish to succeed in it.
