Uncharted 3: Drake's Deception Cheats

In Chapter 5: London Underground, after finding the car in the underground, you will enter the secret library. After a few cutscenes, you will get a map and encounter a small group of enemies who are shooting at you. Leave the library, and go up the stairs to your right (where you originally came from before entering the room). Go around the railing until you reach the midpoint at the end of the room. Jump down to touch the crocodile and get the "Ride The Crocodile" trophy.

If you find all of the relics throughout the game, you can unlock a new play mode & extra levels. In the extra level you get to play as Sir Francis Drake and well, know the truth behind his expedition.

Similar to Prestige for Call of Duty, Legacy Mode can be unlocked after you level up to Level 75 on multiplayer online. The game will ask you if you're interested in Legacy Mode, where you were start from the beginning at Level 1, losing all your boosters, unlocked guns, and unlocked mods. You will receive a new emblem with a diamond at the corner and new negative boosters which will hinder you but increase your cash intake. You will be allowed to keep treasures, unlocked special guns from treasure sets, and unlocked skins.

Beat all five Co-op Adventure maps on Crushing and you receive a silver star by your rank. To unlock the Crushing difficulties you must beat the maps on any difficulty beforehand.

In Chapter 4: Run To Ground, after entering the underground section, you will reach a cylinder looking structure that leads to a lower level. Before going all the way down, climb to the very top and grab the Strange Relic to get the "Relic Finder" trophy.]

In Multiplayer mode, Drakes wetsuit (DCL) says "Ottsel". This is a reference to Jak And Daxter (Daxter is an Ottsel) from Naughty Dog.
