This guide will let you know where to find Cyclops Engine, Hull, and Bridge Fragments in Subnautica (EVERY LOCATION).
Starting from the coral tube that sticks up out of the water, you have to head southeast on the compass towards the back of the aurora until you reach the crash zone. At this location, you can find engine fragments as well as bridge fragments. The main threat you will encounter at the crash zone is reaper leviathans, you can simply avoid them.
But if they start to get close, then you need to make sure you have a sea moth with perimeter defense on it to ward them away, so you can look for fragments. You can also find engine fragments inside the aurora in giant/big crates you can randomly find throughout the ship.
The next place you might be able to find fragments is in the crag fields and to get there, you have to start from the coral tube again, and head south until you reach the crag fields. At this location, you’ll only be able to find engine fragments.
The main threat you will encounter while searching through the crag fields is bone sharks, which aren’t all that difficult to deal with, but they are annoying as they will constantly attack your sea moth even while you aren’t in it. So if you’re going to be searching using your sea moth, then make sure to have perimeter defense to ward them off. But if you aren’t, then make sure you have a stasis rifle and your sea moth is in a high enough place so they won’t attack it.
You also might need to Mk1 depth module for your sea moth depending on how deep/far you explore the crag fields so keep that in mids as well.
The next place is going to be the northwestern mushroom forest which you can get to by again starting from the coral tube starting point and heading just in between west and northwest on the compass until you reach the forest. At this location, it is possible to find both bridge and hull fragments.
The main threats you will encounter here are Bonesharks which you will encounter in very small numbers, so they won’t be much of a threat. You might find a Crabsquid towards the right side of the forest, so be aware and try to avoid it if you do happen to see it as it can disable your vehicle/electronics. You have to do the same thing for Bonesharks as you did in the crag fields if you encountered them there.
Anyways, the next place will be the underwater islands wreck, which you can reach by starting from the coral tube starting point and heading north until you reach the underwater islands. You’ll be able to find engine fragments there.
The main threat you will encounter here is going to be Bonesharks and a lot of them at that, so make sure if you bring a sea moth, you need to put it near the surface so they won’t destroy it while you are out scanning the perimeter defense. You need a stasis rifle and a Thermo knife if you want to kill them, will all help to keep them at bay while you’re trying to search for fragments.
Now the second to the last location is going to be both the sea treaders path wreck and the sea treaders path itself. To start, you have to use the same coral tube starting point and head about 2 bumps on the compass to the right of southwest until you run into a large wreck in the sea treaders biome. You might be able to find bridge and hull fragments at this location.
There is one main threat you may encounter here both at the wreck and on the sea treaders’ path and those area warpers can warp you out of your sea moth or whatever vehicle you are in and attack you. So it is recommended to bring a knife/Thermo knife with you as if it teleports you out and you damage it enough, it will warp away from you. You can also try to use perimeter defense if you are quick enough or just avoid it entirely though they do seem to kind of chase you more so be careful of that.
From the wreck, you’re going to go straight west for a few hundred meters until you reach a sort of cliff/drop, and when you go down that drop, you will find a large/long path along with maybe a few sea treaders walking around on it. This is how you’ll know that you are in the right place. From there, you’ll just search the path for fragments scattered around the area.
For the last spot and probably the most dangerous, you have to go to the mountains Biome wrecks. To start off, you need to use the same coral tube starting point and head about 2 bumps to the left of the northeast on the compass until you come across the first large wreck in the mountains Blome. You might only be able to find engine fragments here.
It is highly recommended to have a Seamoth with perimeter defense as well as an MK2 depth module before coming here. You will also need a stasis rifle. The two main threats you may encounter here are Reaper Leviathans and Warpers, you need to avoid them.
To get to the second wreck in the mountains, you have to start from the first one and head just in between northeast and east on your compass until you come across a smaller wreck on a sort of Hillside.
