Caves

Now we're in Eckhardt's lab. Well, actually, we're still in the cave. Run ahead. Slide down the slope to the left. Jump out of the slide to the left onto the platform to avoid the first blade. From here, take a running jump onto the safe ground on the other side. Run down to get to the alchemist's laboratory.

In the Laboratory

Here in the lab you'll meet two aggressive skeletons, so move quickly. Or, if you have enough ammo, you can force them to jump into one of the water shafts. Use the lever on the left to open the large trapdoor in front of you and the one above the ladder. Then run up the stairs. In the right corner you will find an Alchemical Vial #1 (Pure Oxygen). Collect this. Under the wooden floor you will find a small medipack. Now climb up the ladder to reach the balustrade. Run to the left. You can use the first vial on the machine up here. Now jump onto the cage from the place where the ladder ends at the top.Take a close look at the ceiling of the cage. At one point there is a trapdoor through which you can get inside. Collect the Alchemical Vial #2 (Pure Hydrogen) here. Now you have to be quick, the cage is starting to fall. Quickly climb back onto the roof. The quickest way up is to run to the wall where the roof hatch is. Climb up there and shimmy to the right or left so that you can pull yourself onto the roof. From the roof of the cage you can now crawl into the crawlspace in the water shaft. Here you can collect the Alchemical Vial #3 (salt). Climb back up the crumbling wall. Make a backflip to get out from the top. Now use the last two vials at the bottom of the machine and in the room with the other water pool.

3rd Crystal Shard

The large pool of water has now cooled down. Jump into it. Dive down and collect the 3rd crystal shard (mine is the 28th) The gate at the top of the laboratory opens. Run to it and step through. Use the slide down. You stop at the bottom in front of a gate. Step towards it so that it opens. Run into the centre of the arena.

Video

The video shows Eckhardt trying to awaken the sleeper. Lara confronts him and proudly presents the shards she has collected. She is determined to put an end to Eckhardt's activities.

Showdown

Now you have to take care of Eckhardt. And that will be a nasty business. He'll alternate between firing a volley of electricity blasts and a volley of fire blasts.

In both cases, try to stay far away from Eckhardt and duck down, or even better, lie flat with crawling and stealth. Shooting at Eckhardt is a waste of time! If Eckhardt jumps into the air, he will appear a short time later on the other side. Always crawl a little in a circle near the centre and you'll make it out unscathed.
Don't be confused by the action when Eckhardt creates 3 copies of himself. These will then run to the centre, where the real Eckhardt will reappear, apparently weakened. As soon as the electricity/fire has disappeared, you must run to the centre and press the action button to send a shard into Eckhardt's body.

You must do this until all three splinters have been placed.

Video

However, Lara will not place the last splinter herself. Joachim Karel appears.He will take the splinter from Lara, but then ram it into Eckhardt's head. He will tell Lara that Eckhardt worked for HIM, not the other way round. It turns out that he is a shapeshifter. He appears briefly as Bouchard, as Luddik, even as Kurtis.

Now watch the next video.

Karel

Now you have to fight Karel. Collect Eckhardt's glove. Then run to the pillar to the left of where Eckhardt is lying. There you can activate the switch with his glove. Two ladders will be lowered. Run to one of these ladders and climb up. Run to the next ladder and climb further up. Turn left along there. Behind the platform with the control panel you will find another ladder. You also have to climb up this one. Take a running jump from the overhanging platform to the sleeper.

Endvideo

This starts the end video. (END.mpg; you can also find this in the AoD folder on your hard drive if you picked the full installation and start it from there) Karel is killed. Lara finds Kurtis' Chirugai, which twitches suspiciously when she unfolds it. She retracts the blades and walks into the darkness.
