-- Secret #1 --
After standing on the dummy floor and landing on a pushable box in the "Vilcabamba"
section, move the pushable onto the unique tile floor across from the other unique
tile floor which has a puzzle hole and a raising block will activate along with a
camera. Follow the path and monkey swing which unlocks a door containing a shotgun.
That's secret #1

-- Secret #2 --
After killing the baddies in the area with the bookshelves past the swinging blades,
activating the switch will not only trigger a trapdoor but raise a raising block.
This block is back in the room before ths swinging blades with all the statues. 
Use it to pull down the ceiling trapdoor and grab the uzi's. That's secret #2.


-- Secret #3 --
After killing the shiva in the TR3 India inspired section play along with the trap
and activate the first switch which opens the gate at the other end of the room.
Sprint down and stand in front of the second switch but DO NOT ACTIVATE it straight
away. You need to wait for the spikes to come a little bit close (but obviously not
too close otherwise you'll die) A guide of the perfect time to pull the lever is a
second or two before the music ends so when the event music begins to die down it 
is the ideal time. Then when the gate you came through reopens, run to it and wait
for the spike wall trap to past and then immediately run back into the trap room
before the gate shuts you out. Now run to the opposite end of the room that you
were never able to get to before because the spike wall was coming at you and 
there will be a crawl space. Crawl and reveal secret #3 with Uzi ammo, shotgun shells
and a grenade launcher!! Climb up the ladder and try all the walls to find a pushable
block you can pull out to leave the area. That's secret #3
