Showing up casually late to the marketing party, here's a trailer featuring the multiplayer modes in The Last of Us. They seem to draw from the same well of brutality and paranoia evident in the single-player game.
The Last of Us is genre-defining experience blending survival and action elements to tell a character driven story about a population decimated by a modern plague. Cities are abandoned and being reclaimed by nature. Remaining survivors are killing each other for food, weapons and whatever they can find. Joel, a ruthless survivor, and Ellie, a brave young teenage girl who is wise beyond her years, must work together to survive their journey across what remains of the United States.
