Masters of Teräs Käsi takes place between the Star Wars movies A New Hope and The Empire Strikes Back. The destruction of the Death Star at the hands of Luke Skywalker has severely crippled the Galactic Empire. The Emperor wants retaliation against him and all of the Rebel Alliance and seeks the services of assassin Arden Lyn to eliminate the Alliance's key members. Luke and the others find out about the Empire's plot and challenge Arden, face to face. "Teräs Käsi" refers to a martial art used in the game; both words have been borrowed from Finnish and they literally mean "steel hand".
