The miniatures game Striker is a science fiction tactical wargame that was published by Game Designers' Workshop in 1981 as a boxed expansion to the Traveller role-playing game.[1] It was notable for attempting to cover a broad range of technological levels and having an intricate "engineering" style of vehicle design by the player using formulas and tables. A later game, Striker II, was based on the systems in GDW's Command Decision WWII rules and tied to the role-playing game Traveller: The New Era.
