Choplifter! is a side-scrolling action/arcade game that puts the player in command of an attack chopper. The mission: Go behind enemy lines and rescue up to 64 hostages. However, the chopper can only carry 16 passengers at a time, so several rescue attempts must be made to rescue everyone. Be careful, though, because tanks and enemy aircraft will try to stop you - and they won't stop shooting while the rescuing of hostages is going on. Originally released for Apple II home computers, Choplifter! was later ported to the Colecovision in a rare instance of a home version receiving a later arcade release. However, while the basic gameplay stayed the same, alterations were made. The game now consists of four different levels. The original's desert level has been redesigned, and three new settings (sea, caves, and city rooftops) have been added.
The player must rescue at least 20 hostages to complete a level. Each level contains only a total of 24 hostages, and the chopper can now only carry 8 passengers at a time.
A fuel system was added, where a unit of fuel gets refilled for each hostage returned safely. A scoring system was also added.
New stationary ground-to-air missiles enemy units have been added to make the gameplay more challenging.
The Famicom and Sega Master System versions are based on this Arcade version, with slight differences in levels and gameplay mechanics.
