Note: I am NOT a speedrunner, so my videos are not perfect. I'm uploading these as a way of showing people the shortcuts and glitches that I have seen online and can prove whether or not they work on the PS2 version of Tomb Raider: Anniversary. They may work on other versions, they may not. I don't know, so please don't ask me about it. Apologies about the video quality. I don't have a means of recording my console gaming except for taping off of the television with the digital camera. This one is pretty easy, although it's not a huge time saver. To perform it, just use the stairs to get on top of it (or climb up manually; whatever you like) and roll through the gap above it. It might take one or two rolls, but Lara will get it. After you pull the switch, climb out through the part of the gap with the most space. Keep pressing the climb button or Lara will usually just fall back into the room. Good luck.
