It's BS. First of all, that picture shows a map that has already been confirmed to be named "Dome", not "Paris". Second of all, read the description. "A HUGE AREA FOR A GREAT TEAMWORK AND FOR A NICE GAME. MOST COMPATIBLE FOR TEAM DEATHMATCH AND BOMB."
It's already been confirmed as fake. In two days there'll be practically no secrets about Call Of Duty left, so what's the rush?
