Choplifter! is a side-scrolling action 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.
The gameplay involves navigating through four different levels, each with its own unique environment and challenges. The player must rescue at least 20 hostages per level, while avoiding enemy fire and trying to complete objectives such as destroying enemy aircraft and tanks.
Choplifter! was originally released for Apple II home computers, but later ported to arcades in a rare instance of a home version receiving a later arcade release. Alterations were made to the original version, including new levels, reduced passenger capacity, and added features such as fuel replenishment and scoring systems.
The game's various versions, including Famicom and Sega Master System ports, share similar gameplay elements but have some notable differences. The Sega Master System version, in particular, has a unique level structure and requirements for completing levels.
