Buzz!: Quiz World developed by Relentless Software is the ninth game in the Buzz! series of quiz games. The game is available for PlayStation 3 and PlayStation Portable consoles. It allows users to use question packs purchased for previous Buzz! games as well as supporting user created content and online play. Unlike the previous PSP Buzz! Buzz: Quiz World (PSP) supports DLC. As with all previous Buzz games the game is available in a game only (Solus) version or in a bundle which includes 4 wireless Buzz! Buzzers and a USB dongle for wireless connectivity (each dongle can connect 4 buzzers to the PlayStation 3).
