Croft Manor: Gold statue
Before you can get the gold artifact, you must complete the Bolivia level. Otherwise, the rest of the manor will be closed off. After you enter the manor, get the grapple. It is located in the computer room in a safe behind Zip. To unlock the safe, use a laptop on the floor. After you get the grapple, get the pistols in Lara's bedroom. To get the pistols, there are two knives that both need to be pulled. Then, go head to the library. To your right is a wall that can be broken by shooting it. Once that is done, move the bookcase in the wall to one of the pressure switches on either side of Allister's desk. Then, use the grapple to get down the other bookcase, which is above the pressure switch on the right. Put that bookcase on the other switch and a wall will open up. Grab the PLS on Allister's desk. In the dark hallway is a switch. After you pull it, a large stone tablet with a clue will come out of the wall. The clue reads "Above the Waters, Twin Sisters turn their backs one upon the other to leave the Ambages unguarded". Go to the end of the hallway and pull the second switch. Another wall will open up and lead you back into the bedroom. With the first clue in hand, go to the pool. On the right side of the pool there are two fish statues that can be pulled out. Do so, then jump onto the shortest one. Jump on to the pole, swing to the ledge, jump to the other statue, onto the second pole, then onto the balcony. There are two Greek statues. Rotate them so they face away from each other. Once they are in position, another clue will appear: "Within the Hall of Knowledge, Tomes of Cerulean, Topaz, Viridian and Crimson in turn reveal their Arcanum". Go back to the library. Push in the blue book to the right of the door. Then, go to the small room upstairs. Push in the yellow book, then the green book, outside the room. Go back downstairs and push in the red book. After you do this, a wall will open, revealing the third clue: "Above the Hearth, revealed visage and countenance touched in haste raise up the Steward". Go back to the front lobby. To the right of the door leading to the library is a switch that just came out of the wall. Before you use it, use the grapple to pull out the poles leading to the other switch. After that, push the switch, swing to the other side, and use the other. The fourth and final clue then comes out of the wall: "The risen Athena turns to face the Sun, whose burden then reveals the Golden Laurel". A statue has arisen in the middle of the front lobby downstairs. Turn it so that it faces the window above the stairs then stand on the pressure switch. The statue then goes back into the ground and a stone pillar with the Golden Artifact appears from the ground in its place.

Ghana: Gold statue
At the end of the level, when you stand on button that opens the timed door, do not enter that door. Instead, go to the under the door to find a golden statue.

Japan: Alternate costume
When you reach a room which has a hanging dragon in it, you will find a large red box. Throw it to the floor to break it. You will get a gold statue that gives you a new costume.

Kazakhstan: Project Carbonek Boss
After the creature is released, run around the dome. Turn the switches on by pressing Y. When you have pressed all the switches, four balls with come down from the ceiling. Get onto the magnetic gun in the middle of the room. Make the balls come to you by using the magnetic gun. This might take some time because the monster will keep knocking you of the gun. When you have all the balls pointing towards you, a chamber will open above your head and the sword fragment will appear. Get off the gun and point up towards the sword fragment and grapple it. When you have it, an intermission sequence will begin and the level will end.
