Choplifter (チョップリフター) is a 1982 Apple II game developed by Dan Gorlin and published by Brøderbund. In the game you pilot a helicopter and must rescue people from prisoner of war camps.
The success of Choplifter meant it was brought to a variety of platforms including the SG-1000 in 1985 and the Sega Master System in 1986. Sega were also responsible for an arcade port to both Sega System 1 and Sega System 2 hardware.
Though Choplifter II was a Nintendo Game Boy exclusive, Choplifter III was ported to the Sega Game Gear.
One of Sega's own games, Air Rescue seems to be inspired heavily from Choplifter.
