Lost Valley: Attacking raptors safely
When you slide down the slope and the raptors charge at you, ready to attack, there is a rock where they cannot get you. As soon as you enter the valley, jump on the rock on your left. You will be able to shoot them and they will not be able to attack you.
Midas Palace: Turn golden
Have Lara stand onto Midas' hand until she turns to gold.
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.
Better jumps
When jumping up stairs, pull out guns but do not shoot. Hop forward and you will glide smoothly up the stairs.
