Interlock

""The Interlock System is R. Talsorian Games' proprietary role-playing system. It is one of the direct parents of the Fuzion system (the other is the Hero System). The Interlock System is a "skill-based" system - characters are created by choosing skills for them, and by advancing those skills individually; rather than by choosing character class packages. The Interlock System is used primarily in the Cyberpunk 2020 and Mekton role-playing games; a variant of the Interlock System is used in Teenagers from Outer Space and the Japanese Gundam Senki RPG."
