Heading into a subway ends with Joel and Ellie having to work their way through Spore fog as a short cut to their next destination - Bill's, a man who owes Joel a favour of some sorts. We also see a very hurt Joel laying down some ground rules for Ellie.

*The Last of Us* uses a third-person perspective and 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 has 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 player's weaknesses, such as when Joel runs out of ammunition or when he is being attacked by other enemies. The player's variety of abilities mean they have multiple ways of accomplishing the same objective - this is typified in the "crafting" gameplay ability which allows the player to gather various items in the world and combine them to make weapons or items, for example gathering alcohol and rags and choosing to create a healing pack or a Molotov cocktail. The player will need to craft items quickly and at a carefully chosen time, due to the action not pausing while crafting takes place.
