Updated on June 15, 2025, by Ritwik Mitra:Subnautica: Below Zero is an excellent sequel that improves upon most aspects present in the first game. The mechanics of the series have never felt better, making for a wildly enjoyable experience as players comb through the open world of this game and uncover all the secrets that lie within.
Players who want to augment the gameplay of this title even further should check out the following mods for Subnautica: Below Zero.
15Better Teleportation Tool
Teleportation is extremely convenient in a game like Subnautica: Below Zero where players need to gather materials in one area to be used somewhere else. However, the Tether Tool can be somewhat frustrating to use since it completely depletes one Ion Cube.
With this mod, players don’t need to worry about such grievances anymore. Now, the Tether Tool will start charging up instead and can be used by the player after a certain time… that they can decide for themselves too!
14No Shiny For You
The Sea Monkey is one of the most annoying creatures in Subnautica: Below Zero. While this creature doesn’t do anything, for the most part, things take a turn for the worst if the player uses a tool in front of them.
Entranced by the shiny thing in the player’s hand, Sea Monkeys will attempt to steal this tool for their own purposes. It can be incredibly annoying to deal with at times, which is why it’s great thatthis mod makes it so that Sea Monkeys don’t irritate the player anymore.
13Advanced Storage
In a gamethat prioritizes crafting a lot, having a big inventory is a must. While the inventory size in the vanilla version ofSubnautica: Below Zerois pretty serviceable, some players would want fewer restrictions when it comes to inventory space.
This is wherethe Advanced Storage modcomes into the picture. It allows players to customize their inventory space as they see fit, allowing them to alleviate the frustrations that would arise from a limited inventory size.
12BetterSeaglide
The Seaglide is an entertaining way to roam the depths of Subnautica’s oceanic landscape. However, after a while, the novelty of this vehicle wears off somewhat.
Thankfully, players can make the experience of using the Seaglide way more entertaining withthe BetterSeaglide mod. It allows players to customize the light settings and color of the Seaglide. Along with these changes, players can boost while using this vehicle too!
11Terraforming Ability
Crafting and building are a huge part ofSubnautica: Below Zero. However, the game doesn’t go all out with this mechanic, restricting players from changing the terrain of the world itself to suit their base-building needs.
Withthe Terraforming Ability mod, this feature is added to the game. Now, players can create truly aesthetic bases that don’t limit their creativity in the slightest!
10Fast Loading Screen
Out of all the mods on this list, this one is the simplest of the lot. The change it brings might be a minor one but can alleviate a ton of frustration for gamers with competent systems that don’t need to spend too much time loading in the first place.

The function ofthe Fast Loading Screen modis pretty self-explanatory. Most players might not even notice the swiftness brought about by this mod, but would sorely miss it if it wasn’t present after getting used to it.
9Replenish ReactorRods
Reactor rods are some of the most useful resources in the game. Watching these valuable energy resources deplete and become useless is rather painful to bear after a point.
With this mod, the depleted reactor rods can be made useful once again by using certain resources. It’s a great way to promote sustainability in the world ofSubnautica: Below Zero.
8Map Mod
It shouldn’t take an expert to guess whatthis moddoes. After all, it’s pretty much mentioned in the title itself. With this mod, players can finally make one of the most critical aspects of the game somewhat more manageable —exploration.
It can get a little frustrating roaming the world ofSubnautica: Below Zeroat times. This mod can serve as a useful way to alleviate the frustrations some players might face in the game due to the lack of a proper map.
7More Quick Slots
The number of quick slots inSubnautica: Below Zerocan feel woefully inadequate at times. Console gamers might find the idea ofaccessing five quick slotson their controller to be perfectly reasonable, but it’s a different story for PC players.
The keyboard doesn’t really have any limitations when it comes to assigning keys for multiple actions. So,with this mod, players can utilize a total of ten quick slots instead, which is quite useful throughout the game.
6Advanced Inventory
As is the case with the quick slot mechanics, the inventory ofSubnauticais definitely serviceable for players using a controller. However, with a keyboard and mouse, many gamers would want more options to access the inventory with ease.
