GURPS AutoduelLife in the Fast Lane . . . Just Got Faster! GURPS Autoduel was one of the first worldbooks ever published for the GURPS system over ten years ago! Its post apocalyptic world, based on the classic Car Wars boardgame, was a fan favorite as players faced a world devastated by war, famine, and despair . . . on lawless highways where the right of way went to the biggest guns. Ten years later, things have gotten better in Autoduel America but not much.
