Welcome to the brutal world of The Last of Us. Sure we are promised some kind of infected humans in this apocalyptic world, but the first true gameplay video Naughty Dog has decided to show for the game is all about surviving against other humans. In this video Joel and Ellie, the two main characters, are working their way through a ruinous city towards a bridge and run into a bit of trouble inside an old hotel. The AI is really impressive and Naughty Dog, the maker of the Uncharted series, is effectively showing that they are still one of the best developers out there. They are callign this AI system the Balance of Power AI. The enemies will try to flank you, surprise you and intelligently alert their friends as you try to take them as efficiently as possible. I immediately compared The Last of Us to Ubisoft's I Am Alive, where you had the option to not kill people, because Naughty Dog sure makes it look like you are a murderer and you have no option not to murder other survivors. Anyways, take a look at the trailer. Be back with more later probably, if not we will have quite a bit tomorrow once we get back from E3.
