How To Use Laser Cutter In Subnautica

Okay, so you're cruising around in Subnautica, minding your own business, probably getting chased by a Reaper Leviathan (because, let's be honest, it happens to the best of us), and suddenly you realize you need to cut through a door. A locked door. A door practically screaming for a bit of laser surgery. That's where the Laser Cutter comes in. Think of it as your underwater crowbar, only way cooler and infinitely more sci-fi.
But how do you actually use this magnificent piece of tech? Don't worry, it's not rocket science. Unless, of course, you're also trying to build a rocket in Subnautica, then… well, good luck with that! This guide will walk you through it. Imagine it's like learning how to operate a fancy microwave, but instead of reheating leftovers, you're melting through reinforced steel. Same same, but different.
Step 1: Getting Your Hands on the Laser Cutter – The Crafting Conundrum
First things first, you gotta actually have a Laser Cutter. You can't just wish one into existence (trust me, I've tried). You need to craft it. This involves finding the blueprint, which is usually scattered around wrecks. Think of it as a treasure hunt, except the treasure is a high-powered cutting tool and the map is often partially eaten by sea creatures.
Must Read
Once you've got the blueprint, gather the ingredients. You'll need:
- Battery: Duh. Power source is kind of important.
- Diamond: Because everything is better with diamonds. Even underwater laser cutters.
- Titanium: The unsung hero of Subnautica crafting. You’ll need a lot of it.
Head to your trusty Fabricator, shove the ingredients in (figuratively, please), and poof! You've got a Laser Cutter. Congratulations! You're one step closer to becoming an underwater demolition expert.

Step 2: Equipping and Charging – Power Up!
Now that you've got your shiny new Laser Cutter, equip it from your inventory. It takes up a tool slot, so make sure you're not trying to hold onto your scanner, knife, and repair tool all at the same time. Inventory management is key, my friend. Think of it like packing for a weekend trip, but instead of clothes, you're bringing potentially life-saving equipment.
Important! The Laser Cutter uses battery power. So, make sure it's charged. A depleted Laser Cutter is about as useful as a chocolate teapot. You can recharge batteries at a Power Cell Charger back at your base. Consider having extra charged batteries handy – like carrying spare phone chargers, you never know when you’ll need it!
Step 3: Finding a Target – Where to Cut?
Alright, so you've got a charged Laser Cutter, you're ready to roll. Now you need to find something to cut. Look for those sealed doors or metal panels with obvious cut points. They're usually marked with some kind of crosshair or designated cutting area. It’s basically Subnautica saying, "Hey, cut me here!".

Sometimes, finding these doors can be tricky. Keep an eye out for them in wrecks, Degasi bases, and other underwater structures. They're often guarding valuable resources or story-related items, so it's worth the effort.
Step 4: Cutting Time – Let There Be Light (and Sparks!)
This is the fun part! Aim the Laser Cutter at the designated cut point. You'll see a laser beam appear. Hold down the use button (usually left mouse button on PC) and watch the magic happen. The Laser Cutter will start melting through the metal. You'll see sparks, hear sizzling sounds, and feel a deep sense of satisfaction.

The cutting process takes a few seconds, so don't release the button until the door is fully open. And be careful! Sometimes, things can get a little... spicy behind those doors. Be prepared for potential hazards like leaks, aggressive fauna, or just really, really bad smells (okay, maybe not smells, but you get the idea).
Pro Tip: Keep an eye on your oxygen level while you're cutting. You don't want to run out of air mid-laser-surgery. That’s like running out of gas on a road trip – avoidable and annoying!
You Did It!
Congratulations! You've successfully used the Laser Cutter in Subnautica. You're now a master of underwater entry. Go forth and explore, uncover secrets, and maybe, just maybe, avoid the Reaper Leviathans. Good luck, and happy diving!
