The Last of Us is an Action/Adventure survival horror video game developed by Naughty Dog for the PlayStation 3 video game console, and later for PlayStation 4 as The Last of Us Remastered. It was officially revealed on December 10, 2011 during the Spike TV Video Game Awards and is scheduled for a worldwide release on June 14, 2013 as a PlayStation 3 exclusive.
The Last of Us uses third-person view. The player will take control of Joel, while Ellie will be controlled by the AI. The game will involve gun fighting and melee combat as well as a cover system. The player will fight off the Infected — former humans — and the Survivors — humans that are not infected, but are hostile towards Joel and Ellie. A new gameplay mechanic is a feature the developers call "dynamic stealth", meaning that there are many different types of strategies and techniques that the player can use at any given time as they approach a new situation, to which enemies will react differently. Naughty Dog have developed an AI system called "Balance of Power". This new system allows enemies to react realistically to any combat situation they are placed in by taking cover if they see the player, calling for help if they need it and even taking advantage of the players weaknesses, such as when Joel runs out of ammunition or when he is being attacked by other enemies.
The story is set two decades after a cordyceps-type fungus has killed millions, with nature gradually retaking the abandoned cities and towns. The survivors are hemmed inside quarantine zones, completely under the heel of the United States military, with order and screening for any Infected being viciously maintained under martial law. Joel, a hardened black-marketeer within one of the quarantine zones, goes through an event which makes him promise an old friend that he will get a young, fourteen year old girl named Ellie, away from the harsh regime to a resistance group known as the Fireflies. They begin a journey through the U.S., avoiding the Infected, humanoid creatures whose sole aim has become spreading the fungal infection. Joel and Ellie also have to avoid scavengers that survive outside the quarantine zones who see Joel and Ellie as their latest prey. Adding to their problems, the military is determined to find Ellie and bring her back under their power.
The game was first teased before the Spike Video Game Awards on November 29, 2011, with a billboard in Times Square mentioning "a [PlayStation 3] exclusive you won't believe". Initial trailers showed an apocalyptic event, including riots, epidemic, quarantine, and violence, as well as a clip of the BBC's Planet Earth showing an ant infected with Cordyceps unilateralis, a dangerous parasitic fungus that usually kills insects such as ants. On December 9, 2011, players of Uncharted 3: Drake's Deception spotted an in-game reference to the aforementioned trailer with the newspaper headline "scientists are still struggling to understand deadly fungus". At the Spike Video Game Awards, Sony officially unveiled the game, a brand new intellectual property from Naughty Dog, created by a previously unpublicized 80-person Naughty Dog development team. A gameplay trailer, made up of in-game footage, showed a man and a teenage girl fending off other survivors and what appeared to be people with unusual fungal growth before running out into a dilapidated city covered in greenery, reminiscent of the film I Am Legend.
