Hey guys! Ready to dive deep into the underwater world of Subnautica and construct your very own submarine? Building a submarine is a major milestone in the game, allowing you to explore deeper, access new resources, and uncover hidden secrets. This guide will walk you through everything you need to know to get started on your submarine-building journey. Let's get to it!

Gathering the Necessary Resources

Before you can even think about constructing a submarine, you'll need to gather a bunch of resources. This is where your trusty scanner and habitat builder come in handy. The key resources you'll need include titanium, glass, lead, and advanced materials like computer chips and plasteel ingots. Titanium is one of the most basic resources, and you can find it by breaking down metal salvage scattered around the seabed. Keep an eye out for those rusty wrecks – they're goldmines!

Glass is made from quartz, which is also quite common in the shallow areas. Just swim around and look for those shiny, translucent crystals. Lead, on the other hand, is a bit rarer and is often found in deeper areas or inside cave systems. Bring a light and explore those dark corners! For the more advanced materials like computer chips, you'll need to combine several basic resources at a fabricator. This usually involves things like table coral samples and copper wire. Plasteel ingots require titanium and lithium, so make sure you're well-stocked on both. Lithium can be found in the deeper, more dangerous zones, so be prepared for some encounters with the local wildlife.

Having a well-organized base with plenty of storage containers will make this process much smoother. Nothing's worse than having to swim back and forth because you ran out of space! Also, consider building a scanner room with range upgrades. This will help you locate specific resources more efficiently, saving you valuable time and energy. Remember, patience is key. Gathering resources can be a bit grindy, but it's all worth it when you're cruising around in your very own submarine.

Unlocking the Submarine Blueprints

Okay, so you've got your resources. Now, how do you actually get the blueprints for a submarine? In Subnautica, you usually unlock blueprints by finding fragments scattered around the world. These fragments are often located in wrecks or research facilities. The most common way to acquire submarine blueprints, specifically for the Seamoth or Cyclops, is by exploring these wrecks. Keep your eyes peeled for small, glowing boxes – those are the ones you're looking for!

To increase your chances of finding blueprints, focus your exploration on areas where wrecks are known to spawn. The Safe Shallows and Grassy Plateaus are good starting points for finding Seamoth fragments. For the Cyclops, you'll need to venture into more dangerous territory like the Mushroom Forest or the Sea Treader's Path. Be aware that these areas are home to some nasty creatures, so bring your stasis rifle and a healthy dose of courage.

Once you find a fragment, simply scan it with your scanner. You'll need to scan multiple fragments of the same blueprint to fully unlock it. The number of fragments required varies depending on the vehicle. After scanning enough fragments, you'll receive a notification that the blueprint has been added to your databank. Now you're one step closer to building your submarine! If you're having trouble finding fragments, check online maps or community forums for specific locations. Other players are often happy to share their discoveries and help you out.

Constructing the Mobile Vehicle Bay

Before you can build a submarine, you'll need a Mobile Vehicle Bay (MVB). This handy device allows you to construct vehicles while you're out exploring. Think of it as your portable submarine factory! The MVB blueprint can usually be found in the Safe Shallows or Grassy Plateaus, often near lifepods or wrecks. Once you've scanned the necessary fragments, you can craft the MVB at a fabricator using materials like titanium ingot, lubricant, and a computer chip.

Once you have the MVB, equip it and head to a suitable location in the water. You'll want a relatively open area with enough depth to accommodate the submarine you're planning to build. Activate the MVB, and it will deploy a floating platform. Now you can access the vehicle construction menu. Building the MVB is pretty straightforward. Just gather the required materials – usually titanium, lubricant, and a computer chip – and use your habitat builder to assemble it. Once it's deployed, you can use it to construct your submarine. Make sure to position the MVB in a safe area, away from aggressive creatures. You don't want to be interrupted while you're trying to build your precious submarine!

Building Your First Submarine: The Seamoth

Alright, time for the fun part: building your first submarine! The Seamoth is a great starting submarine. It's small, maneuverable, and can be equipped with various upgrades to enhance its capabilities. To build a Seamoth, access the MVB's construction menu and select the Seamoth blueprint. You'll need materials like titanium ingot, glass, a lead, and a power cell.
