Chopper

Chopper is a Zaxxon clone in which the player must free his comrades who are trapped behind enemy lines. In order to fulfill this objective, the player must fly his chopper over various crowded cities, treacherous deserts and powerful military installations deep in enemy territory while destroying guided missiles and AstroJets. If the comrades, who are waiting for help deep in enemy territory, are found they must be picked up and brought back safely to one of the bases.

As soon as one of the comrades comes into view, an attempt can be made to land the chopper on a small landing site. The comrade will then automatically climb into the helicopter. The player has limited fuel. This can be refueled by landing at one of the bases.
