Friday the 13th: The Computer Game (also known as Friday The 13th) was released by Domark in for the Commodore 64 (1985), ZX Spectrum (1986) and Amstrad CPC (1986) based on the popular slasher film series of the same name. In Spain it was released by Zafiro Software Division as Viernes 13. You have two tasks in the game. You have to find a safe sanctuary (you pick up the Sanctuary Cross and place it in a location to make it a sanctuary) where Jason cannot go and then persuade your friends to gather there. If they get bored or Jason enters they will leave. The problem is that Jason is a normal player moving around the game until he attacks or is attacked. Before Jason attacks, the player is warned so they can take action. You play as different characters that all have different levels of strength, panic and sanity. Jason always attacks the character with the highest panic rating. Scattered around the playing area are ten weapons you can pick up and use.
You play as 5 camp counselors out to protect your kids from Jason Voorhees. Most of your time is spent walking down paths and throwing rocks, knives, and other items at Jason. Occasionally Jason will show up and you have to fight him off.
This title is available for three different computers. The Amstrad CPC has the best graphics and sound. The Commodore 64 version has weaker graphics and sound, and the ZX Spectrum version has the worst graphics and no sound. The Commodore 64 version also has a glitch which isn't present in the other versions where attacking a corpse will bring it back to life.
