The World's Biggest Pac-Man was revealed at the MIX11 conference by Microsoft as a promotion for Internet Explorer 9. It is a browser-based game based on classic Pac-Man gameplay, but it takes place in numerous interconnected maps designed by players. In order to design maps, players must connect the game with their Facebook account. Inappropriate maps can be reported by users and will be removed from the map database. Personal player statistics as well as global statistics are maintained.
