Chase H.Q./Walkthrough

• The goal of the player is to become a police officer of the special investigation team and operate a masked police car to track and arrest criminals who escaped by car. There are 5 stages altogether, each with a different suspect. At the start of each stage, an emergency message will be sent from Nancy in the command room, giving an overview of the criminal to be pursued and the characteristics of the target vehicle used for escape.
• Operate the police car with the steering wheel, gas and brake pedals, and shift lever provided on the cabinet. The shift contains two gears: LO and HI.
• Pressing the button on the grip of the shift lever activates turbo for a certain amount of time, giving you explosive acceleration. Turbo can be used a set number of times in each stage. No matter how many times it is used, the number of uses will be restored in the next stage or after continuing.
• When you start the stage, you must first catch up to the target car within the time limit. The positional relationship between your vehicle and the target vehicle can be observed by the radar placed on the right side of the screen. In addition, the distance to the target car is displayed in the upper right corner of the screen labelled "DISTANCE". DISTANCE has a maximum value of 1024 and cannot be further separated.
• You can earn 200 points for every ordinary vehicle that you pass on the road, and the number of points awarded will increase by 200 points each time another car is overtaken. Crashing will cause the point value to reset to 200. If you come into contact with an obstacle outside the road, you will spin and temporarily slow down, or in the worst case you will stop and you will not be able to move until you are returned to the center of the screen.
• Each stage has a branching path in the middle. If you do not proceed in the direction indicated by the arrow, you will wind up father away from the target car. In stages 2, 4, and 5, helicopters from the Special Investigation Headquarters' aerial photography team fly in and give directions to proceed before reaching a junction.
• When you approach the target car, the message "Escape car found" will be displayed, and the time limit will be restored to the set upper limit. A gauge will be displayed on the left side of the screen. From here, the target car will be repeatedly rammed and damaged. Depending on how you hit it, you can do a lot of damage at once, or you can hit it continuously. If the body hit is successful once, the score of 10000 points x the number of stages will be added, but if you lose and continue in that stage, the score will drop to 1/10. The damage done is accumulated in the gauge, and if the gauge is full and the car is unable to run, the criminal will be arrested and the stage will be cleared.
• If you can't catch up with the target car within the time limit or you can't arrest it after discovery, you will be stopped suddenly and you must choose whether to continue. If you insert a coin within 10 seconds and continue, you can restart the game from the spot. However, the target vehicle continues to run away during this time, so if it doesn't resume quickly, it will be further and further away. Any damage done to the target vehicle is reset to zero.
• If it reaches zero count without continuing, the game will be over with the scene where the criminal breaks through the checkpoint.
• The basic system is taken from Full Throttle, so there are similar bugs (regarding steering and pedal re-centering after a crash).
• There is some information that "the game is cleared when you overtake the target car for a certain period of time", but in this game, even if you run alongside the target car and use nitro, the target car will accelerate to the same speed as your own car. Since you cannot overtake it (the DISTANCE value does not fall below 1), it is unclear whether it is actually possible.
