In his final adventure in search of treasure and glory Nathan Drake, accompanied by his wayward brother Sam, as well as trusty old man sidekick Sully and remarkably tolerant wife Elena, is tracking down some lost pirate gold.

That's all well and good for him, but Naughty Dog have hidden an unprecedented number of collectibles throughout the game, and we'd be very surprised if you managed to find them all without any help.

Aside from the 109 pieces of optional treasure to find (yes, you read that right, there are 109) there are notes and letters from the past you can find to add to your journal, as well as journal entries from Nate himself. We've got the guides to find them - with pictures and everything, look!
