SwampDrop down from the tree house. Go towards the swamp. Now have a look at the map the soldier has given you. Go towards the left corner. Make a standing jump onto the next green platform on the left. (As the red crosses on the card indicate the next spot is further on the left.) So make a running jump over to the green platform closest to the left wall. Turn to the right. You have to jump onto the second platform on the left. Make a running jump. Make another running jump over to the platform on the right closest to the tree. Make another running jump over to the next platform on the right. Make a standing jump onto the next platform on the left. Make another running jump to the platform on the left.
Jump to the platform in the left corner. Climb up into the passage and collect the MP5 Ammo. Return to the platform. Return to the previous platform.
Crash SiteBefore you slide down go forward to the left. There you can see some ammo lying around on a rock. Make a running jump to get there. Pick up the grenades. Now slide down into the valley. Draw your weapons. Kill the Velociraptor. (You might want to take a better weapon than the normal guns.) Follow the path to the right. Climb onto the pillar in the left corner. Follow passage. Drop down on the other side. You'll now come to the crash site. Step out of the corner and shoot the raptor coming from the left. Now run around to the right.
Commander Bishop's KeyIn the right corner you will find a hole. Drop down. Follow the passage and climb out on the other side. Collect the MP5 ammo you'll find there and then drop onto the lower level. In that area you can see a soldier. Don't shoot him. Step forward. Two raptors will appear. Help the soldier kill them. Now run into the corner right of the entrance. Climb up onto the higher level in front. Position yourself between the two trees, the one on the lower level in front. (Press the look button. You can see a large medipack on the branch in front.) From the ledge make a standing jump to the branch of the tree in front. Grab the ledge and pull yourself up. Collect the large medipack.
Jump over to the branch of the next tree on the right and collect the flares.
GoodiesRun along the right side of the plane. There you'll find another passage behind the tree on the right. It's very dark. Drop into the hole and light a flare. Follow the passage. Collect the MP5 Ammo. The door on the left will open if approached. Step through. In the yard you'll see a dead raptor and a dead soldier. Pick up the MP5 Ammo. (Or the rifle if you haven't got it already.) Five Compsognathus will attack you. Kill them. Now pick up the large medipack. In the second alcove on the right - coming from the entrance - is a lever. And in the first one on the left as well. (This will open the door.) Get back outside.
Lt. Tuckerman's KeyNow climb onto the slope on the right. In the next area you can see two soldiers fighting with a raptor. You can decide it you want to help them or leave them to it. One of them leaves you some MP5 Ammo if he dies. The alcove on the left as well as the one on the other side of the stream is empty. (There is also one on the right just behind the slope which is empty.) Enter the one on the right. Follow the passage. You will encounter another soldier fighting a raptor. Help him. Don't step onto the red bridge. It will collapse and you will drop into the water, where some piranhas will attack you. Climb onto the block behind you instead. Climb onto the higher block. On the left you will see a ladder. Climb up. At the top make a backsault. You'll land on a slope. Jump again to land on a branch. Quickly kill the raptor. Jump back to the slope and grab the ledge. Shimmy right. Pull yourself up onto the platform. Jump to the other block and from there up onto the next platform. Pull yourself up. Shoot the next raptor. Jump onto the stone platform and collect the crystal. Now jump over to the tree.
Turn left and walk up to the end. In front is a higher branch, you can reach it if you jump up to the left and grab the ledge. Pull yourself up and collect the MP5 Ammo on the branch on the right. Slide back down.
a. Getting into the Plane (short way)(If you take this shortcut, you will miss some goodies. If you don't want to miss them, skip this section and continue with the next.) Run to the left side of the plane. Left of the hatch you can step onto an elevated heap and step close to the plane. Jump up and pull yourself onto the plane. Shimmy left and pull up onto the plane. Head towards the roof hatch and drop inside. (Skip the next paragraph.)
b. Getting into the Plane (long way)Follow the path on the left side of the plane. Jump from the little hill onto the block on the left. Turn right and jump over to the platform. Pull yourself up. Turn right and walk towards the ledge. Jump forward and press action to grab the ceiling. Monkey climb over. On the right side you can let go to land on a branch. Follow it to the left. Turn right. There you can see another ladder. Make a running jump to get there. Press action to grab it. Climb up. Up on the next branch jump up and press action to grab the next ceiling. Monkey climb along. Shimmy right and let go. You'll end up on some leaves. Jump onto the platform above the gap. Turn around and hang backwards from the ledge. Climb down the ladder. At the bottom shimmy as far to the left as you can. Then climb up onto the platform. Crawl into the gap and follow it. Lower yourself backwards into the next chamber. In the left corner you'll find a block underneath a climbable ceiling. Get onto it. Jump up and grab the ceiling. Monkey climb along. Make a turn at the end and follow the other ladder up into the alcove. Drop down before you've climbed to far.
Lower yourself backwards unto the lower platform in front of the window. Go around the corner and use the lever (1) there. (This will bring up one red grate and lower another.) Climb back into the window. Turn around. Jump up and grab the ceiling. Monkey climb over to the other side of the room. Get as close to the wall as you can. Let go and grab the wall. Climb down till your hands are on the same height as the floor of the alcove on the left. Then climb to the left. Climb up into the alcove. Use the lever (2) there. Lower yourself backwards out of the alcove. Let go and slide down the ramp. Grab the ledge. Pull yourself up and make a backsault onto the pillar with the crystal. Turn around. And make a standing jump to the walkway on the left. Grab the ledge and pull yourself up. (This is the platform where you found the first lever.) Get into the left corner and use the lever (3) again. Again climb into the window and monkey climb into the room. The red grating on the left is now lowered, follow it. Now follow the brown ceiling till you can see the next red grating. (Actually two of them, one still lowered and one in position.)
Instead of turning left to get to the first red grating turn right and face the wall. As you can see it looks climbable. So get as close as you can and let go. Grab the wall. Climb down as far as you can. (Your feet have to be on the lowest step.) Now make a backsault to land in another alcove. Use the lever there. (This will lower the last grate.) Now turn right and walk towards the edge. Jump over to the ladder again and climb up. Climb into the alcove on the right. Turn around and make a running jump over to the big ramp on the right. While sliding down grab the ledge. Shimmy to the left so that you are once again under the opening in the wall. (The second block from the left.) Again pull up and make a backsault to land on the pillar where the crystal was. Again turn around an jump over to the walkway. Climb back into the window. Now again monkey climb along till you reach the opening in the wall at the other end. Collect the Uzi Ammo in the left corner. Climb onto the block. Climb out. From the edge of the cave make a running jump forward to the tree branch. Grab the ledge and pull yourself up. Follow the branch onto the plane. Drop through the hatch.
