River Raid III

An unlicensed sequel to the Activision River Raid release in 1982 that mostly copies the original game play and graphics.

The player controls an airplane in a top-down view over an ocean (vs a river in original) and gets points for shooting down enemy planes, helicopters, and ships.

By flying over fuel-stations, the plane's tank can be refilled. The player can shift side to side and change the speed of the plane.
