We tell you how to find all the secrets on the levels "Smell of Oil for Eternity", "Song of the Petrel", "Siberiade", "Roadside Picnic", and "Crime and Punishment".


Each part of Serious Sam consists of several levels, in which the game developers have hidden several secrets. Standalone add-on Serious Sam: Siberian Mayhem for the fourth part of the shooters was no exception. In this article, we will tell you how to discover all the secrets of the game at each level.


Smells like oil forever

There are a total of 16 secrets in this level:


  1. After arriving, move forward and pay attention to the rusty pipe on the right. Go to its end by the mountain to find an ammunition cache in a pile of garbage. By the way, if you jump onto a pipe from a garbage heap, then on the other side you can find a doll. Picking it up, you will hear thunder, and a rainbow will appear in the sky. This is a reference to Death Stranding.
  2. Keep moving along the coast. When the marker points to the slope on the right, do not rush to climb up. Instead, find a container at the end of the beach, go inside and pick up an item to activate a secret trap.
  3. Now leave the beach by climbing up the slope, and note the broken wooden bridge on the right. Walk along the supports of this bridge to find a secret armor at the very end.
  4. The brightest secret of this level is the hidden rocket launcher. Not far from the broken bridge there is a wooden hut. To the right of it you need to find boards in the ground. Break these boards and jump down into the flooded cave. Get out on land and take the secret rocket launcher.
  5. Follow the marker to the oil rig, inside which a cut-scene will play. As you exit the tower, you will see that the next marker points to the complex ahead and to the left. But to the right there is another road between the mountains. Follow there and to the right. At the very end, in addition to the enemies, there will be a building and several boxes. On one of them lies a secret explosive. Be sure to save at least one explosive you find for the end of the level!
  6. Near the oil rig where the cutscene was played (and where the story marker was or is still pointing), there is a side quest start point on the road. After reading the note, move along the path to the spare oil rig. To the left of it there is a cliff and another destroyed wooden bridge. At the end of it lies a secret armor. Picking it up, you activate the appearance of a bull. It is best to kill him with a rocket launcher. Or you can try using the recently found explosives.
  7. Leave the bridge and go left, along the cliff, to find a tree that stands out from the rest. It has a lot of branches, but looks parched. Get close to pick up an item and activating a secret trap. Two large biomechanoids will appear.
  8. From this secret, move along the mountains to the left. Please note that instead of mountains in the future, the path to the left will be blocked by a minefield. Don't step over the warning signs! In the end, you will find a house with secret missiles hidden behind it.
  9. Continue following the story marker. Deal with several opponents, after taking the shotgun upgrade in the form of an under-barrel grenade launcher. A little further you will need to turn right, passing through a kind of channel. There are round screws in the walls to the left and right. One of them will be broken by enemies. Now there is a hole, and you can jump into it. But for this, pass by, go upstairs and kill the exploding big man. Turn right to find a bridge from which you can jump into that very hole. From there, jump into the portal. This will reveal a secret portal loop, as well as a reference to the game of the same name.
  10. Continue moving until you find yourself in a spacious courtyard, where two green demons attack you at once. They stand on two hills on the right. After the victory, climb to the nearest one and go along the blue bridge into the building. In the far right corner, behind the wall, look for an ammo stash.
  11. When you go down the elevator and find yourself on the railway, kill the enemies and go around the train that you saw when you first got to the location. Secret rockets are hidden behind the crates.
  12. In addition, there are two more trains on the opposite side of the railway, which supposedly block the way. But the train has a concrete wall on the right that you can walk around to find an ammo stash.
  13. When you pick up the machine gun and kill all the enemies, the marker will point up. You go downstairs, under the metal pipes, and in the far left corner, look for a hole in the wall. Behind it will be a secret room with secret explosives.
  14. A little later, a difficult battle awaits you at the location where there is a bridge at the top. On it are opponents using red target designators. There will be a huge enemy on the far right building. Go around this building and find concrete blocks. Behind one of them lies a secret explosive.
  15. After taking out the enemies inside the trampoline building, go outside through the door on top indicated by the marker. There will be a box on the left behind the door. Jump on it, and from there - on the visor above the door to find the secret armor.
  16. In the same place, move to the right and destroy the wooden boxes against the left wall. A fragile wall will appear behind them, which can be blown up by one of the three secret explosives found earlier. To switch to it, use the "1" key (it is also responsible for the knife).

Song of the Petrel

At this level, you can find 11 secrets:

  1. As soon as a new level begins, look to the right and see a blue curved pipe with a red valve against the wall. Jump onto this pipe from the small ledges nearby and climb up to the top ledge to find a secret gadget.
  2. After that, you can go down and jump even lower to the railroad. There are two parallel lines here. On one of them stands a wagon platform with a container on top. Look inside the container for secret armor.
  3. On the other side of the railroad, where you can get on top by raising the bridge (press the button), on the right side, there is a passage leading to the side task "Light it up". Go there and at the first location with enemies and hangar 05, at the end of the fenced area, look for two tanks, between which, behind a box, a secret explosive is hidden.
  4. Go to the Hangar 05 door to update the quest. Follow through hangar 04 to the other side and enter hangar 02. Secret explosives are hidden behind the rack on the right. To get to it, find the barrels on the side of the rack, next to the gate, through which you can jump.
  5. Continue on the blue side quest marker. Move through the field with enemies, along the slope to the left. When the opportunity arises, climb this slope and go forward to the house. There is a snowman next to him. Get close to the snowman to activate a secret trap.
  6. Complete the next part of the side mission by turning on the power. Kill all enemies and get back to the surface. Transport will be nearby. Instead of going back, take the path to the right to find the bunker. It only opens when there is power! Inside the bunker, at the very end, there will be a box with a skill point.
  7. Continue through the game until you see a cutscene in which the sole survivor of the oil plant dies. Kill the enemy with plasma weapons and other opponents, but do not rush to follow the marker through the hole in the wall. On the opposite side of it, in the corner, there is a slab that can be bypassed to get a secret armor.
  8. After the cut-scene, when you get out of the water and destroy the helicopter, the path further will point to an area with large blue columns "1" and "2". Before entering this area, on the right, you can find containers. Between them, there is a passage leading to a secret drone.
  9. Opposite these containers, to the left of the passage, you can jump down onto wooden boards. Then jump into the hole, under which you can see the portal. So you will get to a secret location where you need to kill enemies.
  10. After a long section in which you control a large mech, when Sam gets out of it, turn around and walk back. One of the containers on the left has a door marked with red markers. Attach two explosives to it, activate them and go down to the secret classic level.
  11. Finally, before you go to the yellow marker near the place where Sam got out of the mech, search the containers on the right. On the side of the white (or gray) container, you can find secret explosives. It is convenient if you have already spent one of them before.

Siberiada

This is the largest location in the game, so there is nothing surprising in the presence of a huge number of secrets. There are 27 in total:

  1. Kill the first enemies, get on the snow scooter and drive forward along the road until you see tall blue oil pumps on the right. Some of them don't work. Activate them (2-3 closest ones) by interacting with the buttons outside. Secret oil golems will appear.

  3. Drive further down the road. On the left, there will be an enemy base with a pipe puzzle. There you can get the first keycard, which is needed for one of the secrets on the level. But now you are interested in the forest opposite this base, on the right side of the road, if you move along it in the direction of the marker. So, in this forest, opposite the base (perhaps a little further down the road) there is a metal part of the pump, under which the secret TACT gadget is hidden.
  4. Move forward along the road. On the left, there will be a slope leading to the second base, where you need to solve the pipe puzzle. There you will receive a second key card. And the path to the right leads to the sign of the hunting estate. Move there to start the additional task "Hide and Seek". After the cutscene, follow the blue marker and kill the first two enemy waves. Walk between the rocks. There is a purple object on the mountain to the left. Go a little further, climb the rock on the left and go back to pick up a secret gadget.
  5. A little further than the hunting estate (the passage where you just start the task by reading the summary of the missing girl), on the right side is an oil complex. There you need to solve the third puzzle with pipes to get the third key card. Outside, near the buildings are square fuel drums, reinforced with a metal frame. Between the barrels, secret missiles are hidden in the middle.
  6. Drive along the road between this complex and the passage to the hunting estate, towards the marker. This path leads to a sawmill. On the right, there will be a building with a tractor. Climb up the logs in the courtyard to the roof to find a secret explosive.

Around the corner will be the entrance to the next room, where there is a container with a skill point. It opens exclusively with the help of three key cards.

  12. Keep moving forward until you see the ruins of a ruined church. A red scorpion will appear next to her. On the right, there is a field with a red item in the center. Pick up this item to trigger a secret trap.
  13. Opposite the field, behind the ruins of the same church (where the red scorpion appears), you can find an armed snowman. Destroy it for the secret to count.
  14. Continue through the game until you reach the bridge, which is surrounded by an energy barrier. Follow the cable and power poles to the right until you find a shed with four buttons. They need to be blue. Behind the shed is a small building. Secret cannonballs are hidden behind it.

  17. Do not climb back, but go right along the gorge under the bridge. At the end of the path there will be a pipe that leads to the corridors of the bunker. There is a door on the far side. It opens with a button that is hidden with the equipment in the room on the left. This will take you to the secret classic level.
  18. When you get to the first demonic turret, pay attention to the field on the right side. There is a lone silo with a secret gadget hidden on top.
  19. After destroying the first turret, you can go forward but first move to the right, to the location of the second demonic turret. This is important because after destroying each turret, you will be able to pick up a key card. Three keycards are needed for another secret in the level. So, on the way to the second turret, there will be a fence and a house. Hidden behind the house on the right is a secret gadget (hover scooter).
