Journey to Silius, known in Japan as [rʌf] World, is a 1990 side-scrolling run and gun video game developed by Tokai Engineering and published by Sunsoft and Mattel for the Nintendo Entertainment System. The game was released in Europe and Australia in 1990, in Japan on August 10, 1990 and in North America in September of 1990.
Journey to Silius was originally based on the 1984 film The Terminator, but the licensing rights to the film were lost during development. As a result, the graphics and storyline were altered to accommodate this change, but remnants of the earlier version still remain in the game. For example, the final boss has a striking resemblance to the titular terminator in the film.
In the year 0373 of the new space age calendar, overpopulation of Earth has led to increased demand for emigration to space colonies. Jay McCray, the son of a scientist responsible for development of space colony #428 in the Silius Solar System (SSS), prepares to move there in order to follow in his father's footsteps. However, the space station is obliterated in an explosion, killing the entire research team and destroying all data on board.
In his father's home, Jay discovers a floppy disk containing not only the complete SSS colony plans but a personal message from his father asking that he complete the projects should terrorists succeed in destroying the colony. To protect the colony plans and to avenge his father's death, Jay sets out to fight the terrorists responsible for the space colony's destruction.
The player controls Jay McCray, as he goes on a mission to defeat the terrorist group responsible for his father's death. There are five stages, consisting of the ruins of a space colony, an underground concourse, the enemy's hideout, a flying spaceship, and a factory. The player must fight his way through an assortment of robotic enemies and security systems in order to reach the end of each stage and fight the stage's boss. The controls follow the standard conventions of other side-scrolling action games for the NES. The character can lie down, but he can only aim his gun left or right. In addition to the default handgun weapon, the player can switch to one of five additional weapons that can be procured throughout the course of the game (a shotgun, a machine gun, a homing gun, a laser rifle, and a grenade launcher). Each of these special weapons consumes the player's Gun Energy gauge and once it runs out, the player will automatically revert to the default handgun. The player can replenish Jay's health and ammo by retrieving energy capsules dropped by defeated enemies.
After the fifth and final stage is completed and the ending is shown, the player will restart the game on the first stage.
