A picture from an ad in Uncharted 3: Drake's Deception with the phrase: "Scientists are still struggling to understand deadly fungus", is doing the rounds on the net, with the general assumption that it is connected with The Last of Us, a game set to be unveiled at the Spike TV Video Game Awards this Saturday. Could it be a Naughty Dog title? The easter egg in Uncharted 3 could be related...
Anyway, it's food for thought at this point.
