A Taiwanese website's got some very official-looking Left 4 Dead 2 posters that appear to unveil the final two Left 4 Dead 2 campaigns. We're still calling this a rumor, because other sites are doing it, and - you know - peer pressure and all.
Take a look at these things, though. If they're fakes, the artiste who made them may very well find him or herself working at Valve before too long.
Allegedly, the campaigns are titled Hard Rain ("Come Hell and High Water") and Dead Center ("Prices Aren't the Only Thing Getting Slashed").
Thanks, Evil Avatar.
