By now, you might have the idea that you can upgrade your weapons using the parts collected throughout the game. However, to upgrade your weapons, you are going to need some tools too.

You can find 5 of these boxes throughout the campaign and if you are looking for their locations, read on. For more help on The Last of Us, read our Joel Supplements, Weapon Upgrades and Crafting Guide.
