Hint: Flip in the air:
Instead of jumping forward or backward and pressing Roll immediately, press the opposite direction. For example, if you jump forward, immediately press Down and Lara will do a flip in the air. Do the opposite if you jump backwards.

Hint: Finding Lara's basement and race course key:
Go to the Library. When Lara walks in the doorway, there are two bookcases to the right. Approach the one on the left and press Action. Lara will pull a book and the fire will extinguish, allowing her to climb up the side wall inside the fireplace. After reaching the top, follow the passageways until reaching a room with two levels, with a lever on the top level. Pull the block that is on the floor towards the lever. When Lara pulls the switch, the basement door will temporarily open. Quickly run through the attic, and down to the main hall to reach the basement. Once in the basement, walk through to the second room and look in the tank on the right side. Inside are keys to the race course. To collect it, pull the block in the other room to the center. Climbing up to that hall leads to the tank. Then, proceed out of the attic. Do not go back down the fireplace, as it has been re-lit.

Hint: Lara's museum:
Activate the switch on the back of the diving board in Laura's pool room. Go to the door it opens in her lobby. Pull the lever, and quickly roll. Sprint straight across her lobby and roll into her museum, barely making it in time. The Dagger of Xian among other artifacts are in her museum.

Hint: Monkey sighting:
Go down the slide in the first level, and jump when you see a log. You will be able to see a monkey on the log.

Hint: All Hallowed bonus level:
Complete the normal levels and unlock all the secrets. The "All secrets" code may be used to do this instantly. The "All Hallows" level will appear at the "Load Game" screen. It is an extra London level.

Hint: Get on top of Lara's mansion:
Go on the rope slide platform. Face the right wall an eighth of the way, so she is looking at the corner. Press Jump, and while in the air, press Look and Down. Release the buttons before landing. Do this twice. When you get on top of the right pillar, jump to the left pillar, then do a running jump to reach the top of the mansion.

Hint: High Security Compound: Killing MP men:
When you are in the cell in the High Security Compound level, jump backwards. The MP man will enter and try to punch you. Run out and press the buttons on each side of you cell. These will open the cells next to you, and the prisoners who are released will attack the MP man. Sometimes only one will kill him, but usually you need to open most of the cells since the MP man can kill the prisoners.

Glitch: Scary sounds in Lara's house:
Start a new game, and enable the "Level skip" code to advance three levels until you get to the level with the scary sounds. Then, press Start, highlight "Exit To Title" and press X. When you return to the regular screen, go to Lara's house and you will hear the same scary sounds.

Glitch: Shoot faster:
Take out your Pistols or Uzis during game play. When shooting at a enemy, turn to the left or right until Lara points with one gun. While shooting turn back to your regular position. If done correctly, the weapons should shoot faster.

Glitch: Slide across floor:
While in Lara's Mansion, go to the kitchen and open the freezer. Go behind the meat on your right, then move to a side. Face the other side and start running. If done correctly, you should slide across the floor and may vibrate.
