Airheart is an action game designed and programmed by Dan Gorlin for the Apple II and published by Broderbund in 1986. It requires a 128K Apple IIe (or later) to run as it uses the 16-color double hi-res graphics mode. After three years of development the game was technically advanced at its time of release using scaled sprites for 3D effects but did not include all of the planned features. Gorlin reworked the game as Typhoon Thompson in Search for the Sea Child for the Atari ST (1988) and later the Amiga (1990) which is closer to what he originally envisioned.
