Journey to Silius, known in Japan as , is a side-scrolling run and gun video game developed and published by Sunsoft for the Nintendo Entertainment System in 1990. Journey to Silius was originally based on the 1984 film The Terminator, but the licensing rights to the film were lost during development. The graphics and storyline were altered to accommodate this change. Gameplay 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 - which are 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 would 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, the credits are shown, and the player would restart the game on the first stage.

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
