Fun Fact: Journey to Silius began development as a licensed Terminator game. When the deal fell through, developer Sunsoft altered the graphics and designed a new game around the assets.
Journey to Silius is a revenge tale. The player takes the role of Jay McCray, the son of a pioneer in space colonization. When terrorists destroy a space station and kill his father in the process, Jay sets out to confront and punish the men responsible for his father's death.
The introduction to Journey to Silius involves Jay's father leaving him a message on a 3.5” floppy disc, which makes this scene supposedly set in a sci-fi world hilariously-dated; but generally-speaking Journey to Silius is a solid shooter with really great music for the 8-bit era.
The side-scrolling shooter gameplay looks and feels a lot like Contra, but unlike Contra the player does not die immediately if they take damage. Jay McCray loses health off a health meter, instead, which he can refill with capsules dropped by his enemies.
