A.B. Cop or Air Bike Cop is an arcade game for Sega X Board hardware, released in 1990. Gameplay is similar to Chase HQ: you are a cop in an air bike whose goal is to arrest a criminal in another vehicle by repeatedly crashing into the vehicle (thus disabling it) before time runs out. On your way to the criminal, you must also crash into his cronies, destroying them. There is one button, which causes you to jump, and an accelerator stick(?).
