The Croft Manor (part 5)
Tomb Raider Anniversary Game Guide and Walkthrough
Shoot the second rope, again behind the crates. So that leaves only one holding the big statue in place.
Now get back to the platform where you threw the box down, and jump on the swing. You have to time it right so you can jump from it on the scaffolding in front of you.
Go around, the scaffolding, and do a backwards jump on the next one.
Then another backwards jump on the balcony. Shoot the last rope, and the statue will fall.
Go down in the hole and grab the decorative box. You'll need it later.
In the tunnel you may want to grab an artifact.
Can't reach the lever just yet. We need water.
Go back to the living room and take the door on the left that'll lead you to the training area.
