Huayna Capac, the last grand Inca, after 500 years of his death, prepares a warrior called El Dorado to gather three gems of Time, Energy and Matter, and fight Aguirre, the Spanish leader.

The quest brings him dodging asteroids, dogfighting with Spanish spaceships, fighting his way through mazes and performing puzzles (rituals) to summon the mummy of Pachacutec the Renovator for hints.

Computer Gaming World stated in September 1993 that despite excellent audio and good graphics "the game failed to achieve its full potential", with abrupt arcade sequences interrupting the story; "As a result, Inca comes across as a loosely strung together series of action sequences, mazes and puzzles", which would "not strongly appeal to either action gamers or adventurers".

[5] In April 1994 the magazine said that the game had "puzzles of modest difficulty and joystick bustin' action sequences",[2] "but the plot and, to a lesser degree, the interface left much to be desired".

[9] A sequel was released the next year, under the name Inca II: Wiracocha, in which the player controls El Dorado and Aclla's son, Atahualpa.
