In this comprehensive guide, we will cover everything you need to know about obtaining and using weapons in Subnautica Below Zero. We detail weapons like blades and guns as well as using the environment and creatures to your advantage in combat and defense.

Bladed Weapons

Survival Knife

The Survival Knife is one of the most basic yet essential bladed weapons in Subnautica Below Zero. It is the first weapon players acquire and serves multiple purposes. This versatile tool can be used for self-defense against aggressive creatures, as well as for gathering resources and cutting through various materials.

The Survival Knife is a reliable companion for any underwater explorer.


The Thermoblade is an upgraded version of the Survival Knife, designed specifically for the icy depths of Subnautica Below Zero. This powerful weapon not only provides self-defense against hostile creatures but also has the ability to heat up, allowing players to cook fish and other creatures for sustenance.

Additionally, the Thermoblade can melt ice formations blocking access to certain areas, opening up new exploration opportunities.

To craft the Thermoblade, players will need to find the blueprint and gather the necessary resources. Once obtained, this weapon becomes a valuable asset in the player’s arsenal, providing both protection and utility in the harsh underwater environment.

Ranged Weapons

Ranged weapons are essential tools for survival in the dangerous depths of Subnautica Below Zero. They provide a means to defend yourself against hostile creatures and to gather resources effectively. In this section, we’ll explore some of the most useful ranged weapons available in the game.

Stasis Rifle

The Stasis Rifle is a powerful tool that can temporarily freeze creatures and objects in place. It emits a freezing pulse that slows down the movement of anything caught in its range. This can be incredibly useful for escaping dangerous situations or immobilizing aggressive creatures while you gather resources.

Just be careful not to rely on it too heavily, as its power is limited and it takes time to recharge.

Propulsion Cannon

The Propulsion Cannon is a versatile weapon that allows you to manipulate objects in the environment. It can be used to grab and throw items, which can be helpful for clearing obstacles or defending yourself.

Additionally, it can pick up small creatures and launch them away, providing a temporary reprieve from their attacks. The Propulsion Cannon requires a bit of skill to use effectively, but once mastered, it can become an invaluable asset in your arsenal.

Gas Weapons

Gas weapons are a unique category of ranged weapons in Subnautica Below Zero. These weapons utilize various gases to inflict damage or provide defensive capabilities. One example is the Gas Torpedo, which releases a cloud of toxic gas upon impact, poisoning and disorienting nearby creatures.

Another example is the Prawn Suit’s Gas Torpedo Arm, which can be used to disperse gas clouds that repel aggressive creatures. Gas weapons offer a different approach to combat and can be particularly useful in certain situations.

Environmental Weapons

Using Extreme Temperatures

In Subnautica Below Zero, players have the unique opportunity to utilize extreme temperatures as a form of environmental weaponry. This involves harnessing the power of freezing or scorching temperatures to gain an advantage over hostile creatures or even defend against other players.

By utilizing specialized tools such as the Thermoblade, players can inflict damage on enemies by subjecting them to extreme cold or heat. This innovative approach to combat adds an exciting layer of strategy to the game, requiring players to carefully consider their surroundings and adapt their tactics accordingly.

Weaponizing Creatures

In addition to using extreme temperatures, players in Subnautica Below Zero can also weaponize creatures found in the game’s vast underwater world. By taming and training certain creatures, players can turn them into formidable allies in combat.

These creatures can be taught specific attack commands and used to defend against hostile creatures or even other players. Imagine commanding a group of loyal, genetically enhanced creatures to protect your base or assist you in a daring underwater battle. The possibilities are truly endless.

One example of a creature that can be weaponized in Subnautica Below Zero is the “Snow Stalker”. These majestic creatures possess incredible strength and agility, making them ideal combat companions. By forming a bond with a Snow Stalker and earning its trust, players can effectively turn it into a powerful weapon.

Whether it’s charging into battle or using its natural abilities to freeze enemies in their tracks, the Snow Stalker adds a whole new dimension to the concept of environmental weapons.
