40 Fathoms

You can think of this mission as being one long, timed puzzle. If you're too slow to complete any of the main puzzles you'll either drown or burn to death. Fun. And despite its relatively small size, 40 Fathoms gets our vote for being the single most frustrating mission in the game. Like it or not, your patience and dexterity will be tested to their respective limits. You've been warned.

Into the Abyss
Start swimming the moment you take control of Lara. Dodge the sharks and follow the trail of debris to the hull of the ship…then locate the anchor and swim into the hole.

	There's nothing like air - no matter how stale.
	Like it says above, there's nothing like air - no matter how stale.

The room where you grab a breath is a good place to kill the sharks. There's never been a better use for that harpoon gun. When they're belly-up, prepare for another lung-busting swim. Dive through the obvious hole in the far-right corner, then aim for the hole in the wall near the top, upper-left corner. Continue through the next area - aiming for the hole in the wall in the far-left corner. Keep up the pressure, make a hard left and aim, again, for the far-left corner. Yank the lever you find and turn around - a trapdoor is now open in the floor just opposite the lever. Swim down and up for another breather. It's worth noting that if you didn't bother killing the sharks, they won't follow you through the trapdoor.

Hook your way around the big pile of boxes, veer right, and swim into the illuminated hole. Go in and pull the switch. Return to the box room. Where'd all that water go? Climb and jump to the copper ledge, then prepare for some real combat. And a can't-miss secret.

Secret 1

After skirting around the edges of the room to grab the trophy, turn to face the room's entrance. Draw your guns and step on the right side of the trapdoor. If you drop from the correct place, you'll land on a towering pillar - and take no damage from the fall. You know what to do to the bad guys.

Once the shootout is over, head for the space between the towering box-like structures in the corner.

Your escape from this area begins when you jump into the small area. The rest is up to you.

After you enter the tiny area created by the boxes, turn right (your left side will be to the wall). The next sequence happens very quickly: Jump up and grab, back flip, slide and jump. All that's required of you, the player, is to hit the jump button two times - once when you back flip, the second time as you slide. Lara does the rest. Put your heels on the back edge of the flat box and make a running jump/grab to the opening in the distant wall.
