Gorillas, also known under the source code's file name GORILLA.BAS, is a video game first distributed with MS-DOS 5 and published in 1990 by Microsoft. It is a turn-based artillery game.[2] With allusions to King Kong, the game consists of two gorillas throwing explosive bananas at each other above a city skyline. The players can adjust the angle and velocity of each throw as well as the gravitational pull of the planet.
Written in QBasic, it is one of the programs included as a demonstration of that programming language. The others are Nibbles (another game), Money (a simple financial calculator), and REMLINE (a program to remove line numbers from old BASIC programs).
QB64 included a copy of Gorillas, adapted to be run at proper speed, until it was removed due to copyright concerns. As the compiler does not support DEF FN for inline functions, the original code was also adapted to use regular functions.
