Did anybody doubt that yesterday’s leak of the final Left 4 Dead 2 campaigns was legitimate?

According to the newly released achievements list, Dead Center and Hard Rain will be joining Swamp Fever, Parish, and Dark Carnival in Left 4 Dead 2’s campaign suite. While neither campaign has been officially announced, Dead Center looks like it finally brings the quartet into a shopping mall, and Hard Rain apparently sends your meatpuppets into a soggy industrial park.
