Inca has been famous for combining many different genres including space simulator and adventure game to form a certain storyline. Although mostly a fighting space simulator, some levels were purely shooting, had maze exploration, and some included riddles that could be solved by combining inventory items.
The setting is an uchronic war between Incas and Spaniards that takes place in space. Levels vary in gameplay, forming a variable and rich gameplay, however the surreal nature of the game (common in Coktel Vision adventures) gives no comprehensive storyline or solution to riddles, which are solved simply by trying random item combinations. Huayna Capac, last grand Inca, after 500 years of his death, prepares a warrior called El Dorado to fight Aguirre, the Spanish leader. Eldorado will find himself in space flying a Tumi-shaped spaceship and dogfight with Spanish spaceships. El Dorado will find himself fighting his way through mazes, or on board the Spanish mothership (actually a Galleon flying in space) trying to escape, he will meet the Aclla and uncover three magical gems that will help him vanquish the Conquistadors.
Its sequel was released in the same year, under the name Inca II: Wiracocha, in which you play Eldorado and Aclla's son, Atahualpa.
This Video Game contains examples of:
- Big Bad: Aguirre the Spanish leader.
- Politically Incorrect Villain: At least one Conquistador will refer to the player character as a "savage".
- Recycled INSPACE: This game is essentially Incas versus Spaniards in space.
