Back 4 Blood developers released a DLC just days ago called Tunnels of Terror which features a whole new area with new unlockable skins, new cards, new Legendary weapons, a new difficulty setting, and a whole lot more.
Alongside these new features come new secrets hidden in various locations waiting for players to uncover. In this guide, we’re going to talk about those secrets and where you can find them.
All Secret Locations in Back 4 Blood Tunnels of Terror
There are a total of 7 secrets in the new expansion, all of which are scattered throughout seven different locations. Let’s have a look at all of them:
Secret #1: 300 Below
From the elevator shaft, turn back and head straight until you come across a passage to the left. Enter that small passage and go straight all the way until you come across a room with huge gears in it. From there, simply head to the left side, and you should be able to find the first secret just hidden beneath a box filled with dirt.
Secret #2: Caustic Cesspool
From the starting area, you want to get your way across. To do so, follow the path to the left then turn right until you come across a broken bridge. Simply jump over it to get to the other side, then turn left and go right until you see the end of a sewer pipe.
Just below that pipe is the 2nd secret. To get to it, slide down the water then turn left and jump up until you find yourself on a ledge. Crouch in order to get through the path, and you’ll then be able to find the second secret at the end.
Secret #3: Bloodstream
For this level, you’ll want to go down an area with a green glow by sliding down on where the water flows. From there, go left, jump on some ledges, then turn right until you find the third secret at the end of another ledge.
Secret #4: The Nursery
In the room with the red glowing heart, climb on one of the roots on the left until you see the fourth secret at the edge.
Secret #5: Brood Lair
This one is a bit long and complicated. From the level’s starting area, head outside and strafe to the left. You’ll be able to see the fifth secret just above a rock formation. However, getting to it is a bit tricky.
To start, turn to the left then go straight, turn right, head straight forward, then turn left, go straight, turn left, continue straight, then turn left until you come across a huge open door.
Enter the door, go straight, then turn right and go all the way up. Follow the path until you come across a platform you can jump on. Simply jump on that platform, then jump onto the next platform which is where the fifth secret is located.
Secret #6: Sunken Passages
You’ll want to start from the nest which is the objective of this level. However, instead of destroying it, head to the left until you come across a small passage. Enter the passage then make your way through the ledges until you get to the other side.
Turn right until you come across an open space, then turn left, and you should be able to see the sixth secret at the top of a ledge. Simply take the path upward on the right and hop up on the ledge to get to the secret’s location.
Secret #7: The Cut
On this level, you’ll want to make your way to the big open area with large branches. From there, follow the path of the large branch in front of you, then at the end, turn left until you come across a small cave.
Enter the cave then follow the path to the right until you come across another big open area with a massive hole. The last secret is actually just hidden on the very edge of the cliff. What you want to do is get close to the edge as possible and point your cursor down until you can find it.
Grounded: The Hidden Chip Location | Rotten Log Chip Guide | Ash Recipe
Travel underwater and underground. Find the Hidden Chip Location and learn the Ash Recipe.
Playing Grounded requires you to take on different adventures including traveling, fighting, crafting, and even collecting items. One of the things that you must collect is the BURG.L chips.
Collecting these BURG.L chips and handing them over to BURG.L will let you unlock new and different gameplay features. However, the chips are located in different map areas and it is your task to find all of them even the hardest ones to find.
In this guide, we will reveal the hidden location of the BURG.L chip in the rotten log. This guide will explain everything you need to know in finding this BURG.L chip.
If you have already explored every corner of the upper yard area of the map, yet are still having a hard time finding the BURG.L chip indicated on the map, then I think you have landed on the perfect guide.
To find that hidden chip, there are a few things that you must prepare with you. These things are the Assistant Manager Keycard, a bubble helmet, fin flops, and a gill tube. These items are necessary for your journey underwater.
But, first things first. You must first head your way towards the abandoned underwater lab. Looking at the lower part of the lab itself, you will see a circular doorway that will serve as your entrance. Interact with it and enter the lab.
As you enter the lab, head upwards and go to the room which is directly on its right. From there, you will see a locked door. Use your Assistant Manager Keycard to gain access to this room. Once you enter the room, you will see a button there. Press it to open up the door that you will need later.
After that, you can still go and check out the whole area to find some more random items and raw science. But this time, we will have to go next to the rotten log location.
If you follow the indication on the map, you will arrive in this area. You will see a tube embedded in the ground. All you have to do is jump on the dents of the log to serve as a platform for an easy entrance to the tube. However, it might take you a while on this part since it is actually hard to land perfectly on the tube.
Once you have succeeded, drop down inside the tube and it will reveal an abandoned lab tipped over.
Basically, you will have to move around by jumping over the fallen equipment to get to your location. Keep jumping until you reach the Stump Outpost. Keep jumping until you reach the damaged section or room above.
Once you reach the room, face right and look for another hole to jump down. You will realize that you have fallen into nasty water. From there, face the right side which has a glass wall that you can see through. Jump over it and jump to the terminal to open the door you found at your first landing from the tube.
After you have activated the door, you have to do another series of jumping scenes until you get back to the top. Then, go back to where you started and you will be able to access Door A.
As you enter Door A, you will fall directly on the BURG.L chip that we are looking for. Get out of the lab by going through the hole with raw science and by following the path.
After you finally found this chip, go and talk to BURG.L. Give the chip you got and you will receive rewards and recipes.
For the Rotten Log Chip, you will receive 5,000 raw science and unlock Stump Chips.
You will have to use the Stump Chips in the ASL Terminal to see what you have unlocked in the Science Shop. After checking, you will obtain Advanced Building: Ash Cement.
Now that you have obtained the recipe for ash cement, here is how to craft it.
First, you have to make Charcoal Ash using charcoal. After that, you can now make ash cement by using 1 rust, 2 charcoal ash, and 2 clay.
