The River

Climb up the wall on the left. The leaves there can be used for climbing. Drop down on the other side. Run towards the pool. On the right is a crate. Pull it to the left once and climb onto it. Jump up to the ceiling and monkey climb to the opposite side. Drop onto the triangle platform and collect the small medipack. You slide into the water. Dive into the passage and turn right. Follow the river. The current will take you to a bridge. Swim over to the jetty on the left. Dive underneath to get some arrows. Follow the river towards the next bridge. In the far right corner you can find some more arrows. Swim over to the left. Climb out. Behind the first and the last pillar of the bridge you can find more arrows.

By the Jetty

Jump back into the water and return towards the jetty. Climb out. Run up the muddy path. On your left you can find an entrance. (Shortcut: Climb onto the block in the far left corner and jump over to the platform on the right. From there you can get onto the bridge.) Enter the entrance on the left. There you will find a ramp. Kill the guard. He loses some flares. On the right you can find some shotgun shells. (This is where you would have come up the ramp if you hadn't gone into the crawlspace.) Now examine the bridge tower the man was guarding. Through the barred window at the end you can look out onto the bridge, where you'll spot another guard. But climb out through the window on the right. Turn left. (This is where the paths join if you have taken the first shortcut.)

The Bridge

Take a running jump over to the left onto the bridge. Kill the guard. He loses some shotgun shells. There are some more on the left. If you look over to the left you can see a little tower with a flag. If you look closely you can see Nessi in the fog. You can see her better when you bend over, looking downwards. Now run over to the side with the dog statues. A crow will attack you. Kill it. Now run towards the steaming alcove. A flock of bats will fly past but they won't harm you. Collect the shotgun shells in this alcove. Now turn right. In the distance you can see another guard. Jump over the gap and shoot him.

Crowbar and Switch

Run towards the wall behind which the guard you shot earlier was hiding. On the right is a little pond. Jump into that pond and collect the harpoons and the crowbar. Movie: You will see another guard in his chamber. Now step into the alcove where the other guard was and use the lever there. This lever is timed. Immediately make a sideflip to the left to get over the wall. Turn left and run along the passage. Jump over the gap and enter the first chamber on the right, before the door can close. Shoot the guard. Collect the small medipack. Turn right and left. In the next yard you will meet another guard. He will open a door ahead. Shoot him after he has done that. Run out into the yard with the gravestones.

Swamp

On the right side you will encounter another guard. Kill him and collect the shotgun shells. In this corner is a swamp and fog. Avoid it. Run over to the left instead. There is another guard who loses some shotgun shells. Run into the direction he came out of. Careful there is another swamp again. Walk towards the edge and make a standing jump onto the pillar on your right. Continue onto the flower covered pillar on the right. Kill the crow before it can push you off the pillar. Make a standing jump onto the lower green pillar on the left. With a running jump without grabbing the ledge you can reach the pillar with the obelisk. Jump over towards the emblem on the right. There you can wade through the mud. In the next chamber turn left.

1st Thistle Stone

Crawl into the passage in the far left corner. Crawl out into the yard on the left. Turn right and take a good look at the dog statues. Run over to the large medipack. As soon as you have picked it up the two dogs come to life and attack you. After they are finished, collect the ammo on the other crates. Crawl back into the passage and follow it further along. Stand up and run along till you meet the next crawlspace. Stand up at the end and climb up to the right. Climb further up to the right and collect the small medipack. Now climb into the steaming alcove. There you can pick up a Thistle Stone (#1). Jump up to the ceiling and hold on to it. Climb along to the left. At the end let go. Slide down towards the pond. You are back where you found the crowbar.

Switch in Tower

Turn right and run to the other end again. Jump over the gap and run towards the tower. You cannot get in from this site as the slope it to steep. Step out onto the bridge and behind the dog statue turn right. Make a running jump into the tower window. A flock of bats comes out. Use the lever inside. This opens a door back by the castle. Now leave through the left window. You will slide down, jump at the latest opportunity to get back towards the castle. Enter the first chamber on the left quickly. Shoot the guard. The lever in the area on the right is for getting out of the chamber if you have forgotten the first thistle stone.

Pit with Strange Fluid

Run into the passage ahead. On the right is a gate where you can place two thistle stones. Run into the passage on the left. Run up the stairs. The steaming dog statue will come to life when approached. Run further up. Run down into the next cave. Note the window high above in front, this will be of importance later on. Turn left and run past the pit. In the left corner you will find some flares. If you look out through the gate you might spot Nessi again. Now look up towards the bridge over the pit. The underside is covered with vine. Position underneath and walk towards the edge of the pit. Jump straight up and grab hold. Monkey climb to the other side. Drop into the passage and crawl through the gap. Turn right and quickly crawl into the next gap to avoid the boulder coming down the hill.

2nd Thistle Stone

Run up to the top and crawl along the upper platform to get into the gap there. Stand up and climb to the top. Shoot the guard on the left and the crow. Run up to the top of the stairs and pick up the medipack in the alcove on the left. Get outside turn right and make a running jump towards the next platform. Grab the ledge and pull up. A flock of bats will come from the right. Step inside. Take a good look at the archway you entered through. It is covered with vine. Picture. Climb up there and jump onto the platform behind you with a backflip. Take a running jump onto the green platform in the middle. There you have to shoot a crow. Collect the MP5 ammo at the end. Then stand at the other end and climb up into the opening. You will come to the roof. Run over to the steam and pick up the Thistle Stone (#2). Kill the crow. Now climb back down. Make a running jump over to the alcove with the small medipack. Pull in and collect it.

Nessi and the Thistle Stone Gate

If you want to make a quick exit without getting all the secrets, jump back towards the green platform in the middle. From there take a running jump towards the broad green passage. Slide down. Run down the stairs to return to the gate where you can use the Thistle Stones. Run down the stairs again. Use your thistle stones at the gate below. Step through and collect the flares. Slide down into the next level.
