Chase H.Q.

In 1988 Taito built an arcade cabinet on a simple premise: you are not a racer, you are a police officer, and your job is not to finish first but to catch a specific car and ram it. Chase H.Q. pushed that idea into a shape many later games copied. The 1989 ZX Spectrum version by Ocean is one of the conversions that tried to bring the arcade sensation to an eight-bit computer.

The structure is rigid. Dispatch names the target, the timer starts, and you tear down the road weaving through civilian traffic. Once you reach the target, the game moves into its second phase: you must repeatedly slam into the fleeing vehicle until it stops. A limited supply of turbo boosts closes distance fast, but at full speed dodging becomes far harder.

Arcade conversions on the Spectrum were always a compromise. The machine had no hardware sprites and no hardware scrolling, so every pixel of movement had to be computed by the processor, and colour-attribute rules pushed programmers toward monochrome playfields. Ocean nonetheless had a reputation for extracting the maximum from those conditions, and its arcade conversions were among the best-selling British software of any kind.

Erbe Software, credited alongside Ocean, was the Spanish distributor through which British games reached the Iberian market — which is why dual attribution shows up on so many titles.

On OldGame.cz you can play Chase H.Q. directly in the browser. It is a good test of how much you can enjoy a fast game running on hardware that was never built for speed.
