Greece - Midas's Palace (part 4)
Tomb Raider Anniversary - Visual Walkthrough
When it's clear, climb up and then jump to the cylinder with the lion heads, move to the side with the box (use the E to move faster when the lions DON'T spit fire) and do a back jump to it.
Flip the second switch.
Next you'll need to jump from one ledge to another on the statues with lions. Just watch the timing of the flames and jump up when it's clear.
If you really can't do this, don't forget you can also download a trainer and set God mode on ;)
This part can be quite tricky since you need to move fast enough to avoid the flames (again, the E key is your friend). The idea is to get to the balcony and pick up the other lead bar from there.
CHECKPOINT
Now just jump into the water and swim back (avoid the aligator of course), then get back to Midas's statue. Some (more) gorillas are waiting for you (yup, definatelly a zoo around here).
For the last switch, notice the crack in the wall and the small platform you can use to jump up.
