ROMMEL'S TREASURE 4: X ZONE

eRIC found this anonymous walkthrough written in French and kindly translated it into English.

Shoot the crate to retrieve the Ankh, the breastplate, explosive arrows and the guard's keys. Use them to open the rusty door, go down and climb forward. At the end, go right and climb. Kill two white SAS. Climb the ice wall and kill another SAS. Climb the ice pillar. At the top, kill another white SAS who lets drop the Uzis. Climb on the left and shoot the crate to retrieve the crossbow and the crowbar. Use it on the switch to open the rusty door on the other side. Before sliding down the big icy ramp, jump in diagonal to the left. At the end of the ramp make a left diagonal jump to land into the opening (you can also jump ahead and grab then shift left to the opening).

Go down the ice ladder then slide until the end. In the little room, go left: a camera shows ammunitions. They are behind the pillar on the bridge where you stand. Make a jump in diagonal, right or left. On the sloped blocks jump immediately to land behind the pillar. Pick up all the goodies: this is SECRET #1.

Now to continue the level you have the choice, either you can go down to the main area from where the secret is located, or )and this is easier) return to the little room by using the same angled jump-then jump, climb in the northeast corner, go down a few blocks, jump to a black ladder and go down. (If you have trouble grabbing the ladder, you can safety drop at the cost of some health.)

In the main area (that we shall call Area A) kill two ninjas. Go right and walk in the water to find another area (Area B) Kill two ninjas. Pick up a small medipack before opening the door. Also check the area to the right of the door for the LASER SIGHT.

Get the ammo, pick up the shotgun and pull the switch: a metallic rolling gate opens in Area A. (Ignore the barking dog for now. He can't get to you, and you can't get to him.) Go back there. In the yard that is now accessible, Lara is looking up to a fuse that must be shot later. Enter the building, kill two ninjas (one in the room, and one who tries to sneak up on you from behind). In one office (to your right) and in the toilets (to your left, down the ramp: kill the two white SAS on the way) you can find ammo and small medipacks. In the office up the ramp with a pink window, kill two ninjas: pick up the revolver and a big medipack that they drop.

Going back down (the left fork going down the ramp leads to a door that's closed right now), shoot the fuse in the yard with revolver+lasersight. Before riding the quad you can find a secret. Light a flare, look up, shoot the opening and jump to it.

On the roof, shoot the crate to retrieve arrows and the two armour legs. Lower Lara back down through the crawl space, get on the quad and turn left out of the garage, then turn right to the beginning of Area A (where the black ladder is), and go down the icy tunnels to a new area: Area C. (Glide along either side of the deep pit to reach the short tunnel leading to Area C.) Dismount, enter the building, kill a white SAS who lets drop the magnetic card, and pull a switch: a camera shows the opening of another metallic rolling gate in Area B. Pick up the nearby large medi-pack. After killing two more SAS when you get back outside (one straight ahead and the other lurking to your left), return to Area B with the quad (taking a right when you reach Area A, and avoiding the water). After the new tunnel to the S, jump over the pit with the quad. Quickly dismount and kill 3 ninjas, then pick up the goodies they drop. Use the crowbar on the switch on the ground, located in the far alcove. (You have to be turned around, facing north, before the crowbar will work.) A gate opens in the alcove near where you shot the 3 ninjas.

Enter the area with many wooden boxes. Shoot another fuse in the SE corner. Continue with the quad (but first, kill 4 ninjas in the next area and drop down into a hole in the SW corner for some revolver ammo) and follow up the ramp. On the upper level, dismount and enter a building on the left by climbing over a block at the end, and kill an SAS. In a corner of the corridor, shoot a grated opening and climb up, shoot another opening and pull the switch in the room with the engine to open the door of the other building across the bridge. But before going back to the quad, continue up the corridor (where you shot out the grated opening) and go to a courtyard to kill two ninjas for fun, then use the crates to jump to the upper ledges for extra goodies.

Enter the new building with the quad. Go down the ramps until a bridge over water. Leave the quad after this bridge and continue by foot in the icy tunnels.

Watch out for the tiny pit as you jump up to the starting point. The fall down there won't kill you, but you'll be unable to climb out. Take a couple of standing jumps S to get to the next bend in the tunnel, then turn right and walk, don't run, to avoid the devilishly disguised lethal pits in your path. When you've passed the second pit, look up to your right and see a building with a closed rusty door at the top of an icy ramp.

Go staight ahead, jumping over another pit, and make a standing jump into the W opening. In the little room, turn around and lower Lara down through a crawl space. The fixed camera does not help to see a switch on the ground. Use the crowbar to open the rusty door above. Come back and climb the ramp leading to the building, using the flat blocks. (Easier said than done.)

When you enter, notice the closed rusty door on the right. In the room with the sentry gun, push the first wooden box, and enter the corridor on the left. Up the ladder in the room with the engine, pull the switch:
the rusty door opens. Return there, dive in the hole of water and swim under the ice until a room from where you can destroy the sentry gun.

Climb on a box to reach an opening. In the corridor, go down the ladder, kill two SAS, pick up the electronical key on a desk and pull a switch to open a metallic rolling gate in Area A. Return to the quad and to the main area. To open the next metallic gate, shoot the fuse near by. Enter the new building with the quad, kill all the baddies, pass the sentry gun, go up the ramp. Climb to the top of the white train and use the crowbar on the switch to open the side doors of the train. Go to the other side, through the train, and up the ramp with the quad. In the large corridor, dismount and crawl over a couple of wooden boxes. In the red room, kill two SAS and pull the switch to open a white door in the large corridor.

Go there in the quad and dismount again so you can climb over another wooden box to arrive in a big room with beds where goodies can be found. Over one of the beds (upper bunk, SE corner), shoot an opening and crawl in. Drop down through a hole and pull a switch that opens a red door located below the white train. Return to the big room with beds. Jump to the upper floor and use the crowbar on a switch to open a red door in the building of Area B. Kill all the baddies and go back with the quad where the white train is. In the room below, you can pick up the Plutonium crystal (a camera shows the red door closed in Area A).

Go to Area B in the quad, enter the building near where you heard the barking dogs you couldn't get to before, kill two dogs in the corridor and two more in the next room over a crawl space. In the next crawlspace, find a room with an engine and push the red button to open the metallic gate in the area nearby that you can see (we shall call it Area D). To find Area D, go back to the main area, turn right and go into the tunnel with the quad.

Just before the area with the lake, there is a closed white door on the left. Shoot the fuse located in front of the door (look up) to open it. Enter in, kill a SAS and use the magnetic card to open the door near by. The next double red doors open automatically. Find your way in the big grey area until a ramp. Jump on a side of the ramp, and make a series of alternative jumps from one side to the other side of the ramp to go up. Push a red button to open un underwater door in the lake. Return there and dive.

Swim until a room where you pick up the Uranium crystal. A camera shows the opening of the red gate in the main area (this door opens when you have both the two crystals). Return to area A on the quad, dismount and enter the newly opened door. Go down until you reach a big cave. Climb the blocks on the left. Turn back and jump to the long platform. Shoot the crate to retrieve the two armour arms and a mysterious key (useless I think). Jump back into the corridor and use the guard's keys to open the double red doors. Use the electronical key on the white machine in the corner. Kill two ninjas and return to the big cave: there is now an opening under the long platform. Go down there and enter a room with a central pyramid. Place the plutonium and uranium crystals at the bottom of the pyramid: the pyramid opens.

Say hello to Horus. End of the level that does not show Lara dressing Horus with the armour.
