Press Triangle + Forward to crawl, then while crawling hold L2 and keep going.
If you die for missing a jump or something similar, which seems to happen pretty often. Before you are taken back to the menu screen, press select. Then hit load game. The game will load from your last save point instead of going back to the main menu.
After returning to the Hall of Seasons w/all four crystals. When you make your way to the higher balcony the Skeleton Warriors will appear. To permanently defeat them shoot them off the balcony. The warriors will fall back down by four raising pillars and disappear like a dead guard. (Note: If there are too many skeletons, I suggest running from them until they stop chasing you, then kill them one by one.
If you want to keep the cleaner from coming do not pick up Wrener's Walking stick. Pick up ammo, guns, and health. When you are ready then pick up the walking stick. The walking stick is right next to you when you start at the beginning of the level.

Stand directly in front of the cabinet and press Triangle (Crouch). When the hand appears, press X (Action). If done correctly, Lara should reach through the door while crouched and grab a gas mask.
This is how you do a hand stand the correct way
when lara is hanging off a ledge hold L1 and press UP and she will do it
all you need to do is tap the L1 button and she will walk like when you hold the L1 button
Most of FAQ and Guides about Angel of Darkness say that you must run and jump the sets in the sanctuary of flames as fast as possible in order to avoid the wave of fire that comes inmediately behind you. But THIS ISN'T completely true. As a fact, you can WAIT at the entrance until the wave of fire has passed and then jump the sets in a easier way, with much more time at your disposition, just taking care not to fall.
Not a Cheat, just a tip!
Save! It is your biggest item/weapon/health. Save before you do big jump or when you are about to do something that will take hours. If you don't save it might take you a while to get back where you were or what you were about to do.
Be Safe and SAVE.
When hanging from a ledge press and hold; L1+L2+R1+R2
While facing a ledge press Triangle then Up on the analogue stick.
Hold L1+Up on the stick and press Circle
Immediately before you exit Galleries Under Siege, equip the shotgun (you cannot just have it on your back). Then, walk through the room to the exit intermission sequences. Once you have control of Lara again, in Von Croy's Apartment, tap Up on the D-Pad. If done correctly, you should have the shotgun on your back. Press R1 to equip it. You should have all the ammunition you had just before the intermission sequences. Note: When you fire, there will not be a sound effect, but it still works. If you shoot it at a wall, you will hear the ricochet sound effect.
