Lara's Home
The first trick we'll explore is Lara's Secret Trophy Room. At Lara's home
press the button behind the diving board to her pool. Then sprint past her
exercise room to her main entrance room (the room with the two staircases). The
button has temporarily opened a door on the right of the room. If you get
through that door in time, pull the lever to open the door directly behind you.
You'll need to sprint/dash to that door and do a running dive to gain access to
a very interesting room.
There is a Huge Racetrack for a four-wheeler to the left of Lara's house once
you exit her main doorway to her mansion. To get the key to the track, you must
pull a book out of Lara's upstairs library and work your way through secret
passages, then the attic, and finally down to a basement aquarium. This is a
blast to figure out, so I won't ruin it by going into more detail today. .
