Hunter Patrol is a shoot 'em up written by Steve Lee for the Commodore 64 and published by Mastertronic in 1985.
The game is similar in style to the Sega arcade game Buck Rogers: Planet of Zoom.
Taking control of a WW2 airplane, the player attacks enemy installations on the ground whilst avoiding enemy planes and flak.
Once a sufficient number of installations are destroyed, the level's main target appears.
When this had been taken care of the player moves on to the next level with the rewards of a score bonus and an extra life.
