The juicy plot details of The Last of Us have reportedly been leaked online. If you don't want the game ruined, which I'm assuming is the case, I suggest you tread the internet with caution.
According to Eurogamer, a few individuals have managed to crack into the demo that came packed with God of War: Ascension. In it they found a list of cutscene names embedded within the code that provide a good indication on where the story goes and ultimately how it ends.
We won't spoil it here, so there's no need to worry. Just be careful from now until the game releases on June 14th if you want to go into The Last of Us completely blind.
