Ghosts'n Goblins, known as Makaimura in Japan, is a run and gun platformer video game series created by Tokuro Fujiwara and developed by Capcom. The first entry in the series was Ghosts'n Goblins, released as an arcade title on September 19, 1985. The series has subsequently been released on and ported to a variety of game consoles and mobile platforms and spawned several sequels and spin-offs.

The main series consists of run and gun platformers with players controlling a knight named Arthur who must battle through hordes of the undead in order to rescue the kidnapped princess Prin-Prin (also known as Guinevere depending on the game/translation) from the demon king Astaroth. Arthur's health and magic level is represented by the armor he wears, with Arthur capable of finding better armor and various weapons in treasure chests hidden throughout the game stages. Once losing his armor Arthur is left only wearing his boxers (an image which has become iconic for the series). In most of the main series, once completing the game the player is forced to re-play the game's stages at a harder difficulty level in order to receive the game's "true" ending. The series has gained a reputation amongst gamers for its high level of difficulty.
