Artelius (アルテリオス) is a Nintendo Family Computer action role-playing video game that was released exclusively in Japan on November 13, 1987.

Players begin the game by customizing and modifying the traits of their character. Warp points allow players to travel across the universe. On the map, the red dots are always bad guys while the blue dots indicate space colonies, where players can rest and stock up on supplies. Each resting spot has at least two doors and/or a warp point. Battles are done randomly and from a first-person perspective. Winning will earn the player valuable experience points that will make the player stronger and advance in levels.

The players attacks are determined by strength while their defensive power is determined by the strength of the shield. Having a high level of agility allows for more frequent successes in running away from unwanted battles. The laser beam is the best weapon in the game; it can be eventually be upgraded to a "hyper magnum" gun that is stronger than a fully powered up missile or bazooka weapon.
