Items are limited in The Last of Us' post-apocalyptic world, and it's up to the player to make the best of those remaining resources. As a new developer diary shows, there's more to it than merely rummaging through drawers to find ammunition.

Joel is resourceful, and one of the ways that attribute manifests itself in the game is through its crafting system. Players can combine items to create new items. It's not a groundshaking innovation, but the video below shows that there's more to it than what we've seen in other titles. Several combinations can be used to create either offensive or defensive concoctions. For instance, the ingredients used to make a medkit also happen to be the same ones that Joel can combine to make a molotov. It's up to players to determine which items are likely to be most beneficial.

See how it works in the clip below.
