Okay, since most of us 'probably' have this now...

...here are some video walkthroughs of the first few levels of the new "Tomb Raider Anniversary" game for PC [and PS2].

The quality is CRAP, but they're good enough to see what's going on...

I found the links on Gamefaqs (which in turn were added from somewhere else...?)

Just thought I'd share some useful walkthrough stuff...

Also there are some glitches for ATI users:

On my Radeon 9700Pro...

1) The "Scorched Natla" costume for Lara has "detached eyelashes" (you can see them floating a few metres above the model)
2) Enabling "fullscreen effects" makes the entire level "seethrough" in underwater areas and some cutscenes...
3) Selecting "Croft Manor" from the title screen AFTER completing the game will crash you to the desktop.
