Stryfe (F) (1986) - Amstrad CPC - Fighting

Wlamir the wizard and Olaf the dwarf are on a mission to slay the evil demon Morvelinh. There are 25 levels (or chapters, as the game calls them), where Wlamir and/or Olaf (you can play on your own or with a friend) collect treasure chests and potions, and destroy the hordes of monsters that are constantly in their way. Each level has four screens, and you must find the silver key and then the golden key, which unlock the door to the next level.
