Easy rolling
To roll easily, instead of pressing [End] press the [Up] + [Down].
Exiting Venice
Give Lara's boat extra power after pulling the switch (right before the clock starts). This will allow it to travel up the long ramp that leads to some windows. Lara will crash through the windows and land in the canal just before the exit with plenty of time to spare.
Alternatively, swim under the mines and you will automatically start the next level with the boat.
Alternatively, pull the switch, then swim under the door and climb back into the boat. The, go to the exit door without beating the clock.
Treasure room
There is a switch in between two statues in the hedge maze at Lara's house that will open a door to a treasure room. To reach the switch, use the following steps from the start of the hedge maze: Left, Right (when you reach an archway), Right, Left, Left, Left, Right, Right, Left, Left, Right, Right, Left, Right, Right, Left, Right, Left, Left, Left, Right. Enter the hole to activate the switch. Pick up flares to use later inside the treasure room. Since the switch is timed, quickly use the following steps to reach the treasure room: Return to the hole's entrance, then go Forward, Left, Left, Left, Right, Right, Left, Left, Left, Right, Right, Straight, Right. Run into house. The door is under the archway to the right when Lara first walks in the house. Once inside, use the switch to permanently keep the door open, then light a flare and explore. The treasure includes items from Tomb Raider and Tomb Raider: Unfinished Business such as the green cat and various idols.
Leaving the mansion
Get to the point on the training course before Lara goes down the death slide. Walk to one of the corners at the edge and face forward. Turn about forty-five degrees and look straight down. While still holding the look button, jump straight up in the air. After the third jump Lara should be on top of the left or right pillar. From here, jump onto the wall, then run around it. Then Lara can jump to the roof of the swimming pool, maze, and even outside the patch of ground outside the gate. Note: If Lara goes outside the gate, she can not return.
Defeating Bartoli
When you reach the end of level 4 (Opera House), Bartoli appears from your left. Take out your shotgun, jump over his head, roll, fire, and repeat. If done enough times, he will die and you will receive little or no damage. Note: Try not to go past the first path to your right when you fall into the room to avoid being attacked by a Doberman.
Defeating the dragon
When the dragon is forming, go to the right-hand side of the room. There should be three pools of water at this location. Enter the middle pool and switch to the harpoons. Surface and start shooting the dragon from above the water. That should drive him behind a pillar in a position where he is stuck and can not breath fire. Use the weapon of your choice and fire until he drops. Then, pull the dagger and evacuate the building.
Bartoli's Hideout shortcut
While going through this level, at one point you will have to jump through a window and kill a man on a balcony. Once you are at this point, kill the man and take the ammunition he has. Then, turn around back towards the window you came through. Walk to the corner of the balcony. Make sure you are in the corner, then start pressing [Forward] + [Jump]. If done correctly, you will jump over the fence to the roof of the building, then slide into the water. This shortcut will save a lot of time and health, but you will miss the Golden Dragon.
Temple Of Xian shortcut
When you get to the bottom of all the waterfalls in the Temple Of Xian, you will end up in a pool with two nasty fish. Kill them if desired. You will see a green colored gate. Swim up to a corner of the gate. Swim along the front of it in a diagonal direction. When you get to the other corner, turn so that Lara has her back to the gate. Hold [Down] so that she is swimming backwards into it. Press [Jump] and Lara should fall through the gate. This works to get back through as well.
Help from monks
In the level with the monastery, you will find a group of monks. Do not kill them. They will kill the enemies with the guns through the entire game.
Glitch: Elevator jump
Walk up to any ledge that has a column next to it. The ledge would be shaped like an "L". Turn at an angle so that you are almost facing the column. Keep in mind that you should always stay at the edge of the ledge. Jump once and as you reach the ground, let Lara finish her "normal position" foot movement. Then, hold "Jump" to jump one more time. Keep the button pressed to will suddenly fly up to the very top of the column. You can do this on the training course of her house on the top of the last obstacle or level, and then explore.
Glitch: Wrong controller icon
When in the Floating Islands level, open the inventory ring and press Down. Where the arrow keys "were", is a PlayStation controller.
Glitch: Stats box order
At the end of the Floating Islands level when the stats box appears, the order of secrets (if you have collected all of them) from left to right is Gold, Silver, Jade. Yet in other levels the order from left to right is Gold, Jade, Silver.
