Forbidden Forest is a game designed by Paul Norman, published by Cosmi Corporation in 1983 for the Commodore 64 and Atari home computers. In this game the player controls an archer, armed with a bow and a limit of four quivers of arrows per level. The aim is to move through a forest setting while eliminating various monsters, including giant spiders, bees, mutated frogs, dragons, wizards and snakes, with the final enemy being the "Demogorgon". The game has four levels of difficulty which determine the number and speed of the monsters. This is one of the earliest video games to use animated blood.
