Hints

Quick Flare:

To use a flare without going to the inventory, press Select + R1 (or R2 if R1 doesn’t work) anytime or when Lara is not holding any weapon.

Stay Ahead of the Head:

In the second level you will have to fight a stone head (but it will fire lasers at you). To beat him you will have to combine your revolver with your laser sight, when you meet him aim and shoot him in the eyes (he will fire his lasers every 3 seconds so be careful but I did not have any trouble with him).

Special Options Menu:

To unlock the special options menu first load up a saved game (mine was on the 13th Floor). Then die. When load game/exit to title appears, choose exit to title. It should then be open with designs for a new Tomb Raider game and storyboards. Alternatively, just complete the game.
