There are 3 pistol upgrades available in the game. Each is unlocked by finding a percentage of the total bronze and silver rewards in the game. It doesn't matter which level you're playing, as soon as you reach the required number of rewards, the pistol upgrade will be applied. Lara's PDA shows your progress toward the next upgrade.
Increased Magazine Size (pistols hold 40 rounds) 25% of bronze and 25% of silver
Increased Accuracy (accurate at greater distance) 50% of bronze and 50% of silver
Increased Damage 75% of bronze and 75% of silver
From the main menu, choose Extras > Outfits to view all the clothes you've unlocked for Lara. Once you have unlocked an outfit, you can try it on by going to the bedroom in Croft Manor (also reached through the main menu). Lara's closet will look familiar to anyone who's played The Sims. ;) Just walk in and follow the on-screen instructions to change outfits.
Although you can't choose Lara's outfit when starting a level for the first time, you can change outfits before replaying a level. This option is on the same screen where you choose the difficulty level.

Finding bronze rewards throughout the game unlocks short profiles for Lara and her friends and her enemies who appear in the game. These can be accessed through the Extras menu. Here's how to unlock each one:
If you're stuck on the part where you gotta get into the temple after you fall dowwn a short waterfall then heres the trick: you take the pole on the left and make face the wall with your grapple hook and you take the one on the right and make it face the water.
You go to the left of the temple and climb up to the ledge and then swing to the slope and slide down it and jump onto the pole and then when it turn around jump off and press X to use your grapple to swing to the other pole and then make your way up to the chain and make it to Author's sarcophogas made outta crystal.
You must beak it open to get the piece of excalibur. To do that you must take a piece of a broken sarcophagas and take it near the piller, climb on top of the sarcophagas and climb to the piller.
Then there is this thing next to you so you must grab the rope on top of it and a bell will be strung up but before you do all of this you must take a chandeler and swing it toward the direction of the bell then you do the rest and then there will be a cut scene.
The sarcaphogas will open you get the piece of excalibur and then you get out. Then this giant snake-like monster will appear and you have to fight it. To deafeat it you must shoot the hollow statues, the monster will be drawned to and then you use your grapple to lower a cage and then the cage will hit the monsters head.
You do that 4 times and then it dies. The body will float in the water and help you get into a passage. You can handle the rest on your own.
