Subnautica: Below Zero players will inevitably come across some areas or containers that they can't access. These can sometimes be sealed doors, sealed containers, or even walls of ice. In order to get past these obstacles, players will need to make use of the Laser Cutter tool, a powerful item capable of cutting through these seals and even providing a little bit of light. Like most things in the game, however, crafting this will require players to first find fragments of it and scan them. Thankfully, these fragments spawn in the same places and are relatively easy to find.
By now, Subnautica: Below Zero players should be familiar with the process of scanning fragments, but in the event that this isn't the case, the process is simple. Players just need to get close enough to a fragment of the technology they want to create and then use the Scanner to collect data about it.
In order to craft a Laser Cutter at the Fabricator, players will first need to find three different Laser Cutter Fragments, but there are more than three fragments that can be found out in the world. Players should check Arctic Kelp Caves, Koppa Mining Site, Mercury II Stern, Phi Robotics Center, and Twisty Bridges, as these are all possible areas that the fragments can spawn. Players can also find them inside of Sea Monkey Nests, presumably because these curious creatures find the fragments and take them back to their nests.
Head back to a Fabricator and players will now be able to see the recipe to craft their own Laser Cutter. The recipe does require a lot of materials though, as players will need to gather up two diamonds, a battery, a titanium, and a crystalline sulfur. The titanium is easy to find, and players probably already have an abundance of it, but the rest is a bit more complicated. Batteries are made in the Fabricator out of ribbon plant and copper ore, and diamonds are a rare resource found on the seabed in certain biomes. Finally, getting crystalline sulfur in Subnautica: Below Zero requires players to find it in Arctic caves or harvest it from sulfur plants.
Each door that the player cuts through with the Laser Cutter will use up about 17% battery. If used efficiently, this means that the Laser Cutter can go through five doors completely before players need to start thinking about replacing its battery.
