Save On Medipacs
If you are low on health, wait until you get to a checkpoint. Save the game at that point. Load the game. This will take you to where you were previously and with a full health bar. This is useful, as it saves on medipacs which you will need later in the game. Alternately, if Lara is low on health and you do get to a checkpoint, kill Lara (for example, jump off a high ledge). This will also take you back to the previous checkpoint with a full health bar.
Style Units Level
Collect all relics to unlock the Style Units level under the 'Special' option in the 'Rewards' menu.
The Great Pyramid: Interesting death
in the room after you fight the strange creature that mimics your every move, there should be three horizontal crushers on both sides. Go to the side where the floor that has not collapsed. Pull the lever on that side (just to get the checkpoint). Take out a gun with and wait for the crushers to go back in. Then, run and jump into the path of the crusher when it comes back out with the weapon still out. If timed correctly the impact will throw you into the ceiling with surprising results. Note: This may be somewhat difficult to do.
Turing gold
In Mida's Palace, step onto Mida's hand (which you use to turn the silver blocks into gold), and stay there for a short period of time to be turn into solid gold.
