Monster 4x4 World Circuit is a racing game published by Ubisoft, centering around Monster trucks. It was released in early 2006 on Xbox, and later on Wii as a launch title for the system. It is similar to San Francisco Rush, with huge jumps and vast speed. The game is a sequel to Monster 4x4: Masters of Metal, although it lacks the Monster Jam license. A sequel developed by Ubisoft Reflections, entitled Monster 4x4: Stunt Racer, was released for the Wii in 2009.
