A bit later than planned, Legoland California is going medieval on you.

Originally scheduled to open in March, the new Knights' Tournament, with robotic arms that swivel 70 different ways to create the sensation of a trackless roller coaster, is now set to debut May 26 at the theme park near San Diego. Each 2 1/2-ton arm will carry two passengers who, after crossing over a medieval moat, can choose one of five levels of intensity for their ride.
