All secrets in level 1, “Smell of oil forever”

In this chapter, we can find sixteen secrets. As soon as we arrive at the location, we continue to move forward without turning anywhere and looking at the old sewer pipe on the right side. We go to the place where it enters the rock, and we look for storage with cartridges in the garbage heap. If you jump onto a pipe from a pile of garbage, then on the opposite side, you can find a doll. As soon as we pick it up, thunder will be heard, and a rainbow will appear in the sky. This is an easter egg dedicated to Death Stranding. We follow along the coast. Soon the sign will direct us up the slope located on the right side. Instead, we go to the end of the coast and find a cargo container. We enter there. When we pick up the item, we immediately activate a secret trap. We leave the coast and climb up the mountain. Look at the broken bridge located on the right side, and we pass through its remaining parts. At the end of it, we select secret armor.

The brightest secret of this chapter can be called a hidden rocket launcher. Not far from the bridge is a wooden house. On the right side of it we are looking for a boarded-up hole. We break all the boards. We jump into the flooded gorge, and then we get out to the surface and pick up a secret rocket launcher. We follow the marker to the oil rig. Once there, watch the video. As soon as we leave it in the story, the marker will point to a large oil refinery located on the left side.

Look to the right to find another path between the rocks. We go along it and turn to the right side. We fight with opponents. In the distance, we will see a couple of containers and a building. On one of the boxes, we can find secret dynamite. Try not to forget: leave one explosive at the end of the level to get to a secret DOOM location (read below).

Near the oil rig where we watched the video, there is a side path with the starting point of the side mission. We read the note and move along the road to the spare oil rig. On the left side of it there is a cliff and another wooden bridge. We pass to its end and select secret armor. This will result in the appearance of a demonic bull. We eliminate it with the rocket launcher found earlier. You can also pre-lay explosives.

We leave the bridge and follow to the left, along the cliff, until we see a tree that is different from the rest (withered). We approach him and select the only first aid kit. A secret trap is activated. In the distance, two large biomechs will appear. Destroy them or run away. We move past the rocks located on the left side. A little later we will see mines. We continue to walk without stepping over the warning signs.

After a while we will see a hut, behind which we can find secret missiles. We go to the indicated mark on the map and eliminate several enemies along the way. We select an enhancement for the shotgun – an underbarrel grenade launcher. We pass a little forward and then turn to the right side. There are round ventilation holes in the concrete walls to the right and left. Opponents will knock out the last grate on the right. Now you can climb into this hole. We pass by and go up. Eliminate the huge kamikaze and turn right. We jump from the metal bridge into the formed hole. We fall inside the ventilation shaft to get into the teleport, in which there is a secret portal loop. Once in a spacious courtyard, we will be attacked by two green opponents. They are located on 2 buildings located on the right side. Having won, we rise to the first and enter the building along the bridge. In the right corner, behind the wall we are looking for a storage of cartridges.

We are waiting for the moment when we go down the elevator and get on the railway tracks. We eliminate opponents and go around the train in front of the elevator. Secret missiles are hidden behind the crates and slabs in the corner. On the other side of the train tracks, there are 2 trains that seem to be blocking the passage. The train on the right side has a concrete slab that we can walk around to find the ammo storage.

In one of the following combat zones, we select the AK-47 and eliminate the opponents. The marker tells you to go upstairs. We are going down below, under the iron pipes. In the corner on the left side we are looking for a gap in the wall. Behind it is a room with a secret dynamite. After a while, we will get to a location with a couple of big men using machine guns. Also, snipers will sit on top of the bridge, whose weapons are supplemented with laser pointers.

In the distance, on the right side is a building on which there is a large enemy. We go around it and see stone slabs. Behind them we are looking for secret dynamite. We eliminate opponents inside the next building with platforms for jumping and leave the room through the door located on top. On the left side behind the door is a container. We jump on it, and then – on the stove above the door. There is a secret armor hidden here. Then we move to the right side and break the wooden containers near the left wall. Behind them is a thin wall that can be blown up with any dynamite found. In order to select dynamite, use the “1” button (the same button as the knife selection). This is the last secret on the first level.

All secrets in level 2 “Song of the Thunderbird

In this chapter we can find eleven secrets. Having started the level, we look to the right side and see a curved blue pipe with a red tap against the wall. We jump onto it from the small ledges that are nearby and climb to the upper ledge, where we are looking for a secret device. Then we go down and jump onto the railroad tracks. There are two parallel tunnels with rails. In one of them there is a platform wagon, on which a cargo container was installed. We climb there and inside it we find secret armor.

We go back up, press the button to raise the bridge, and go to the other side. On the right is an opening that leads to the side mission “Light it up”. We follow there and in the first location where the hangar number 5 is located, we are looking for 2 white cylinders. Between them, behind the container, we can find secret dynamite. We pass to the door of the hangar number 5, the mission will be updated. We head through hangar number 4 to the opposite side and enter hangar number 2. Behind the shelves on the right side we are looking for secret dynamite. To get to it, we are looking for a barrel on the side of the shelves, in the corner, through which you can jump.

We follow further to the index of blue color. We move through the field with opponents, along the mountain on the left side. As soon as we can, we climb this cliff and follow forward to the building. Near it we can find a snowman. We approach it – a secret trap is activated. We continue to carry out the mission until we activate the power supply. We eliminate the arrived opponents and get out. There is a vehicle nearby. We do not return back, but go around the building and look for a path on the right that will lead us to a secret bunker. It will open only if we have applied power. At the end of the shelter, we can find a container that contains a skill point.

We continue moving until we see a cut-scene with the death of a surviving oil refinery worker. We kill all enemies. We are in no hurry to enter the building. Instead, we go to the other side of the building and look for a slab in the corner, behind which there is a secret armor. We watch the video and get out of the water. We eliminate the helicopter and see that the road points to the territory with huge blue columns “1” and “2”. Before entering this territory, we are looking for cargo containers on the right side. Between them there is an opening that leads to a secret drone. There is a fence opposite the containers. We come closer and look down. We jump on the boards, then we fly even lower, into the teleport. Thus, we get to a secret location where you need to eliminate opponents.

We pass the episode with fur. As soon as we get out of it, we turn around and follow in the opposite direction from where we came. On one of the cargo containers on the left side, we can find a door that is marked with a red label. We attach 2 dynamites to it, activate them and go down. We will find ourselves in a secret classic level. Before you go to the yellow marker, which is located near the bridge, on the right side we are looking for cargo containers. Next to the light container we can find a secret dynamite. This is the last secret of the second level.

All secrets in level 3 “Siberia

Siberia is considered the largest location in the game, because a large number of secrets are hidden in it. There will be twenty-seven in total. We eliminate the appeared opponents and jump on the snow scooter. We drive along the road until we see blue devices that produce oil on the right side. Some of them are inactive. We turn on 2-3 nearby equipment to appear secret oil golems. We go forward to the marker, and to the left of the distant pumps, we find a small mountain, which you can climb without a scooter. There we find a secret hover scooter.

We go further along with the marker and turn left from the checkpoint. On the left side is the opponents’ territory, where you need to solve the puzzle with pipes. For this, we get the first key card. It will be needed for one of the secrets on the level. Then we move between the trees opposite this base, on the other side of the road, finding a small piece of equipment with a hidden secret TACT device. We return, past the pumps. We move to the right along the road. There will be a long hill on the left side, on top of which stands the enemy base. We solve the riddle with pipes and pick up the second key card.

The road to the right leads to a road sign pointing to the hunting lodge. We follow there and start the side mission “Hide and Seek”. Watch the video and follow the blue marker. We eliminate 2 groups of enemies and pass between the mountains. On the rock, located on the left side, we see a purple thing. We pass a little forward, climb the mountain located on the left side, and go opposite. There we select a secret device. We return back to the index and with the beginning of the task. There is a fork a little further down the road. The path to the right leads to a large base. There you need to solve another puzzle with pipes to get the third key card. Outside, near the buildings there are square tanks for fuel. Between them we are looking for secret missiles.

We drive along the road between the plant and the opening to the hunting house, towards the marker. This path leads to a sawmill. On the right side is a building with a tractor inside. We rise to the roof with the help of stacked logs and look for secret dynamite. There will be a turn to the left on the way to the sawmill. The path is small and barely visible but leads to a secret cellar with components. It’s time to visit the plot marker. Be sure to take all three key cards with you! We head to the checkpoint, which is marked with a marker, and eliminate two opponents. We go to the other side and immediately turn left. Around the corner is the entrance to the side room, where you can find a container with a skill point. It can only be opened if we have all 3 key cards. As soon as we eliminate the opponents near the temple (twice), talking to Olga. We take a new weapon and leave the temple through the side door. We get to the cemetery. Behind the wall on the left side of the cemetery we are looking for a large tombstone with a monument. There is a special item there. We interact with him to activate the appearance of the holy kamikaze.

We move to the mark on the map and, moving a little away from the cemetery, we see a field with sheds located on the right side. There are 2 blue and red tractors in the barn on the right side. We go around the building and see firewood, behind which you can find secret armor. We are not in a hurry to go to the indicated mark, but instead we follow from it to the left. Across the road, opposite the fields and buildings, we can find the sanctuary of Intertani, one of the heroes of the series.

In order not to take damage from secret explosives you need to shoot the snowman from a distance.

We move forward and find the ruins of a broken temple. A red scorpion will appear near him. Behind this temple, there is a field with a snowman on the other side. Raise the only item to activate a secret trap. We destroy the snowman armed to the teeth. There is a red item in the field to the right of the road. Having picked it up, we activate a secret trap. We follow to the bridge, which is protected by an energy barrier. We go along the cable and pillars to the right side and find a building with 4 buttons. Click on them so that they all light up in blue. Behind the building is a small house: we pass behind it and look for secret cannonballs.

We look to the right side of this house and head to the mountain. Behind the trees we can find the secret TACT device. We return to the bridge, where we previously saw an energy barrier, and under it we find a secret device. We are not in a hurry to get out of the ravine. Instead, follow it to the end to the cave. We go inside through the pipe to be in the bunker. At the end of it is a door that can be opened with a button hidden behind equipment in the room on the left side. We get to the classic secret level.

As soon as we get to the big turret, we look at the field on the right side. We see a silo. A secret device is hidden at its top. We eliminate the turret, take the key card and go forward. We turn to the right side to get to the second turret. After destroying it, we get the second key card. In addition, on the way to the turret, we see a building with a fence. To the right of the building is a hidden device (hover scooter). We move into the passage near the first turret, where the marker points. Then we are looking for a fenced enemy territory on the left. We go around this territory and jump over the fence from a pile of snow. We eliminate opponents and in the house located on the left side, we are looking for a secret device.

As soon as we go down to a large field with a river on the right, we move to the river itself and pass behind the waterfall, located on the right side. We are looking for a secret drug inside. We eliminate opponents and return back. We move past the river and find a high pier. We rise to it and jump through the opening in the center to find the storage of cartridges. There is a mill near the pier and the river. We go in there and lookup. We shoot at the boards from above so that the secret cannon falls.

We go further along the wooden beams and look for a secret device on the side. As soon as we find ourselves in a large location where kamikazes will appear (they will run down the hill), we examine the mountains located on the left side and look for an opening behind the bush leading to a secret hut on chicken legs.

On the same platform, we go to the other end and behind the same building we are looking for a second cache of cartridges. We enter the station building and search the toilet cubicles on the left side. One of them has an ammo storage.

We leave the building and go to the left, without going down to the ground. Around the corner on the left we see a box. We jump on it, jump higher and in the jump we select the hidden secret.
