Make the Survival Knife
Make crafting the Survival Knife using the Fabricator in the Drop Pod one of your first priorities. The main function of the Survival Knife is to procure samples of certain corals and flora such as Table Coral Samples and Creepvine Samples. It can also be used as a weapon but it's damage and range are limited. To craft the Survival Knife you will need Titanium and Silicon Rubber which is made from Creepvine Seed Clusters which can be plucked from the middle of the Creepvine plants. Later in the game you can upgrade the Survival Knife to the Thermoblade by using the Modification Station.
The more oxygen you have in Subnautica: Below Zero the farther down you will be able to dive. This basically means in order to explore for longer you should prioritize collecting the resources needed to upgrade your oxygen tank. The resources required to make your oxygen tank are two Titanium and one Fiber Mesh. Titanium can be found by smashing the interactable rocks you find scattered around the sea bed, and you will need to use your knife to cut down the glowing red Creepvines that grow out of the ground to get the two Creepvine samples needed to make the Fiber Mesh.
Make sure when you go exploring you take a sufficient amount of food and water with you in order to help prevent the health bar in the bottom left corner of the screen dropping to zero. Allowing the health bar to drop to zero will result in your character dying and respawning in the base (except on Hardcore). Although this respawn will cost you a few items from your inventory, the game gives you the opportunity to retrieve those lost items by going to the place where you died.
At the start of Subnautica: Below Zero when you have a limited supply of oxygen it is important that you remember that you are in the arctic zone and the water's surface is covered by ice floes of varying sizes which will prevent you from resurfacing to replenish your oxygen supply. It is therefore important that you pay attention to how much oxygen you have remaining and where the ice floes are above you, so you don't get trapped and suffocate.
You will have limited oxygen when you start out in Subnautica: Below Zero so do not be tempted to explore any deep chasms you find straight away as you will not be able to resurface in them and get oxygen. Hold off from exploring the deeper caves until later in the game when you have upgraded your oxygen tank and Seaglide vehicle so that you have more oxygen and easier movement.
Every time you see something new in Subnautica: Below Zero you should try scanning it. Whenever you scan something it gives you information and helps unlock construction blueprints. It is important that you unlock construction blueprints as the game is equipment-gated from the very start, so you will find it very hard to survive in certain places unless you have the appropriate equipment. Read the PDA for everything you scan as it often give hints about how to use them.
The resources that you can harvest in Subnautica: Below Zero are generally difficult to see and can be easily missed which is something you want to avoid happening. You can make resources easier to spot by adding a colored outline to them by opening the menu, going to 'Options', and checking off the 'Highlight Interactable' box under 'Accessibility'.
Like it's predessor, there is no in-game map or mini-map to rely on in Subnautica: Below Zero. This means you will need to map out your surroundings in your head using your central Drop Pod as your landmark. If you feel overwhelmed doing this you can take a look at the player-made map below to see where everything is, but it is recommended that you resist the temptation of doing this for as long as you can as a big part of the appeal of the Subnautica series is mapping out your surroundings.
