10 Game-Changing Subnautica 2 Mods

Subnautica 2 was released in early access on May 14, 2026, and instantly became a hit — 2 million copies in the first hours and a peak of 467 thousand concurrent players on Steam [citation:3]. But even the best game can be better. Modders didn't delay — just a week after release, dozens of modifications for every taste appeared. From bringing back the ability to kill predators to increasing co-op to 16 players [citation:7]. We talk about the 10 best Subnautica 2 mods that radically change the gameplay.

How to install mods in Subnautica 2

Most Subnautica 2 mods require the installation of the UE4SS loader — a tool that allows script modifications to run on the Unreal Engine 5. Without it, many mods will not work [citation:1][citation:2][citation:5].

Basic installation instructions:

Download and install UE4SS into the game's root folder.
For mod-packs (*.pak), copy the files to the Subnautica2\Content\Paks\~mods folder — if the folder does not exist, create it manually.
For script mods (with main.lua file), copy to the Subnautica2\Binaries\Win64\ue4ss\Mods folder [citation:1][citation:2].
Some mods can be installed automatically via the Vortex mod manager [citation:9].

1. Killable Creatures — bringing back the ability to kill

The main "controversial" Subnautica 2 mod.

The developers Unknown Worlds Entertainment fundamentally removed the ability to kill sea creatures from the sequel. Their philosophy: "We don't make a game about killing." Modders disagreed with this [citation:6].

Killable Creatures brings back the classic mechanics from the first part [citation:2]. All living creatures get a health bar. The basic tool deals 20 units of damage per hit (works like a knife). The acoustic resonator deals 50 units of damage. You can even kill huge leviathans, including the Collector.

When to use: If you are tired of running away from predators and want to clear the area around your base. The mod will be regularly updated for current game patches [citation:2].

2. Too Many Divers — up to 16-player co-op

In the base game, co-op is limited to 4 players. The Too Many Divers mod removes this restriction and allows up to 16 friends to play together [citation:7].

Moreover, the mod developer claims to have implemented cross-platform support. This means that PC and Xbox owners will be able to play in the same session with large groups [citation:3][citation:7].

When to use: If you want to throw an underwater party with a dozen friends or create an entire colony of survivors on the planet.

3. Simple Minimap — a simple mini-map

One of the most useful modifications — Simple Minimap, adds a neat mini-map to the screen [citation:1].

Main features: display of the player's current location and direction of movement; "fog of war" that dissipates as you explore (can be disabled in settings); ability to expand a full map to the center of the screen with the M key; full customization — size, position, transparency, marker colors — everything changes through the configuration file. The H key hides or shows the mini-map on the HUD [citation:1].

When to use: If you constantly get lost in underwater caves or can't find your way home. Especially useful in co-op for group coordination.

4. Better Vehicles — improved vehicles

The Better Vehicles mod offers a balanced set of improvements for in-game vehicles.

What changes:

Tadpole (base model) gets 8 upgrade slots and a slightly increased base speed.
The "Scout" chassis becomes truly fast and responsive, the "rubber ball" control effect disappears.
The "Cargo" chassis gets a slight speed boost, an increased cargo hold, and a clean camera view without intrusive grain effects.
Seafrog also becomes a little faster.

When to use: If you feel that the vehicles in the game are too slow or unwieldy, and cargo holds are always too small.

5. Third Person Camera — third-person view

Many players prefer a third-person perspective, and modders have taken this into account. Third Person Camera allows you to play from behind the character [citation:3].

When to use: If the standard first-person view makes you motion-sick, or you want to see your character and their equipment.

6. Free Building — free building

The Free Building mod removes collision restrictions when building a base.

What the mod provides: the ability to freely place rooms without restrictions; disabling excessive obstacle boundaries when placing rooms; you can change room sizes without conflicts with surrounding objects.

When to use: If you are tired of "not enough space" messages and want to build the base of your dreams without compromise.
