Subnautica 2 Creature Evasion: 4 Biomods That Actually Work

Subnautica 2 creature evasion is the only option. There are no weapons. That's not an oversight or an Early Access gap. Unknown Worlds built the game this way on purpose, and they've confirmed weapons won't be added. When a predator locks on, you've got four Biomods, two tools, and whatever terrain is between you and it. Knowing which works on which creature is the difference between escaping and reloading.

TL;DR: Subnautica 2 creature evasion uses Biomods and consumable tools, not weapons. Camouflage (scan Bullethead) is the only reliable counter to the Shiver Leviathan. Distraction Flares work on the Collector Leviathan but not the Shiver. Electric Discharge (scan Electric Geordie) repels most creatures with a 10-second cooldown. Chum Cloud requires two scans and distracts predators away. Sonic Resonator stuns mid-level threats but doesn't work on Leviathans. Move slowly near patrol zones: rapid movement triggers detection.

Subnautica 2 creature evasion: quick answer

No weapons exist in the game. The full toolkit is four evasion Biomods (Camouflage, Electric Discharge, Chum Cloud, Dash), two dedicated tools (Distraction Flare, Sonic Resonator), and terrain use. Detection triggers on rapid movement: predators patrol zones and respond to fast-moving things, not slow ones. That baseline skill makes every other tool more effective.

The single most important rule: Camouflage is the only counter to the Shiver Leviathan. Distraction Flares don't work on it at all. If you're in the Void biome without Camouflage, you're running on luck.

Key takeaways

• No weapons exist; creature evasion is the only option
• 15 Biomods total, many with evasion value
• Camouflage works vs. the Shiver Leviathan; Distraction Flares don't
• Electric Discharge and Camouflage both stop working inside the Tadpole submersible
• Sonic Resonator stuns mid-level predators but does nothing to Leviathans
• Detection triggers on rapid movement: slow down near patrol zones
• Chum Cloud requires two creature scans before it unlocks

How creature detection works

Subnautica 2 predators respond to movement speed more than proximity. Fast swimming through a patrol zone is the most reliable way to trigger aggression. Slow, deliberate movement through the same area often goes unnoticed.

The Bioscanner (upgraded Scanner from the Modification Station) is how you unlock most evasion Biomods. You start with four defaults: two active, two passive, from the Welcome Center Biolab. The evasion-specific ones require scanning specific creatures or flora in the world. No special facility needed. Scan the right creature and the Biomod unlocks.

Once a predator aggros, the options are: break line of sight, use an active Biomod, deploy a consumable tool, or use Camouflage by stopping completely. That last one is deceptively simple and consistently underused early on.

The 4 evasion Biomods

Camouflage (passive)

Camouflage makes you invisible to predators while you're completely still, including Leviathan-class creatures like the Shiver Leviathan. Any movement breaks the effect, which means finding a stopping point matters as much as having the Biomod active.

Unlock it by scanning a Bullethead. They're found near the Observatory biome and in the Alien Ruins region roughly 510m out, near clusters of red flowers. It doesn't work inside the Tadpole submersible, which is the one situation where it would be most reassuring.

The right place to use it: any zone with Shiver Leviathan patrols. Find a rock formation, stop, and hold position until it passes. Outswimming a Shiver isn't viable.

Electric Discharge (active)

An 800-volt shock that radiates outward from the player and causes nearby hostile creatures to stop attacking. The cooldown is 10 seconds, so if you're being chased by multiple creatures, timing matters. It also stops working inside the Tadpole.

Unlock by scanning an Electric Geordie near the Metal Farm antennas in the Alien Ruins region. Most useful in multi-creature situations where stealth isn't an option. The shock buys you a clean window to break away from a cluster, which is harder to do with any other tool.

Chum Cloud (active)

Releases a bait cloud that lures predators toward it and away from you, with a 20-second cooldown. The important thing about Chum Cloud is it requires two separate scans before it unlocks: a Toxic Sponge (common near Lifepod cave entrances) and a Houndgar (found around 435m east of the Lifepod near the Marrowbreach zone). Scanning just one gives partial credit but no ability.

Since it works by attraction, throw it to the side or behind you, not toward where you're going. Use it when a predator is already pursuing and you need it to change direction.

Dash (active)

Directional burst movement for breaking pursuit. It's a default or early-unlock Biomod, available from the first Ruined Biolab you find. Most useful for breaking initial aggro before a predator builds speed. Against Leviathan-class pursuits, Dash alone won't save you since the acceleration gap closes quickly, but it buys seconds that let you use a flare or reach cover.

Distraction Flares draw light-sensitive predators toward the light source. Throw the flare away from your escape direction before it runs out.

Tools: Distraction Flare and Sonic Resonator

Distraction Flare

A consumable that emits intense light to attract light-sensitive predators. The blueprint auto-unlocks at game start (1 Titanium + 1 Quartz = 3 flares), so there's no excuse not to have them. Carry 5-6 before entering any high-threat biome.

It works on the Collector Leviathan and most standard predators (Houndgar, Marrowbreach, Sandspite). It does not work on the Shiver Leviathan. Throw it away from your escape direction. The flare lures creatures toward the light, not away from you. Where you throw it matters more than when.

Sonic Resonator

The Resonator charges and releases a sonic pulse that stuns mid-level predators (Houndgar, Marrowbreach, Sandspite). Craft it from 2 Titanium Ingots, 2 Lead, 1 Wiring Kit, and 1 Basic Battery after scanning 2 fragments. Hold the trigger aimed at the target, then release to discharge.

It's non-lethal against everything. The developer's description: "The resonator is generally nonlethal. Its pulse may deter attackers, but will not cause long term harm unless the attacker is a solid crystalline object." It doesn't work on Leviathan-class creatures. It does have a secondary use: breaking large resource deposits and Bloom structures, which occasionally makes it worth carrying even in biomes without significant predator pressure.

Which tool works on which creature

Camouflage and Electric Discharge both stop working inside the Tadpole. If a Leviathan aggros while you're in the vehicle, you're down to Distraction Flares (deployed from exits) and terrain.

Creature-specific strategies

Collector Leviathan

The Collector is light-attracted, which makes it the most tool-responsive Leviathan. Flares are your primary counter, Camouflage your backup. Avoid straight-line fleeing. Depth changes, cave entrances, and rocky terrain break line of sight far better than raw speed.

Community approach that works: throw the flare to the opposite side of where you're heading, then use the attention window to close on cover.

Shiver Leviathan

Pack predator in the Void biome. Distraction Flares do nothing. Any contact with its jaws is an instant kill. Camouflage is the only reliable counter. When you detect one, stop immediately and hold position. If there are multiple Shiver Leviathans nearby, staying still is still the right call. Moving gives all of them aggro at once.

Don't enter the Void biome without Camouflage unlocked. This isn't caution, it's just math.

Great Jaw (Clam Leviathan)

Stationary ambush predator. It doesn't pursue. The threat is entirely from approaching its shell-like seafloor structure without recognizing what it is. Distance is the only countermeasure. Once you know what a Great Jaw looks like, you won't aggro one twice.

Standard predators (Houndgar, Marrowbreach, Sandspite)

All responsive to Flares, Sonic Resonator stuns, or Dash. The Marrowbreach Alpha specifically: use Dash during its circling phase, before it commits to attack. Electric Discharge is also effective against all three. These creatures don't need Camouflage. They respond to the cheaper tools.

Electric Geordie

Larger variants can discharge electricity, temporarily stunning battery-powered tools including the Sonic Resonator and Tadpole systems. If your Resonator stops working mid-chase, check whether an Electric Geordie was nearby recently. Keep distance from larger Geordie variants when you need your tools functional.

Biomods unlock through creature scans. Camouflage requires scanning a Bullethead, one of the earlier evasion unlocks once you reach the Observatory area.

GODEEPER: The DNA modification system includes biomods beyond evasion. Scanning flora and fauna unlocks passive upgrades across swim speed, oxygen, and resource collection: the Scanner Room automates a lot of that scanning work once you've built one. Subnautica 2 Scanner Room: Build Order and Upgrades →

Priority unlock order for evasion

For early game survival, get these in order:

1. Dash - available from the first Ruined Biolab, earliest unlock, useful immediately
2. Distraction Flare - blueprint auto-unlocked, craft immediately, maintain a stock of 5+
3. Electric Discharge - scan Electric Geordie in the Alien Ruins area (mid-game access)
4. Chum Cloud - two scans required (Toxic Sponge + Houndgar), early-to-mid game
5. Camouflage - scan Bullethead near Observatory, non-negotiable before Void exploration

Sonic Resonator can be slotted in after Chum Cloud based on when you find its fragments. It handles standard predators well enough that having it before Leviathan areas is useful, but it's not a first-priority unlock.

Frequently asked questions

Can you kill creatures in Subnautica 2? No. Subnautica 2 has no weapons and creatures can't be killed. Unknown Worlds built the game around evasion, distraction, and stealth. That's intentional.

What works against the Shiver Leviathan? Only Camouflage (staying completely still). Distraction Flares are ineffective. This is the one creature where the standard toolkit fails.

How do I unlock Camouflage? Scan a Bullethead near the Observatory biome or in the Alien Ruins region. It's one of the mid-game Biomod unlocks, non-negotiable before Void exploration.

What's the best way to avoid creatures early game? Slow movement near patrol zones, Distraction Flares for diversions, and Dash for burst escapes. Camouflage and Electric Discharge come online once you reach the Alien Ruins area.

Does the Sonic Resonator work on Leviathans? No. It's effective on mid-level predators (Houndgar, Marrowbreach, Sandspite) but confirmed ineffective against Leviathan-class creatures.

Does the Tadpole protect me from creatures? Partially. It's fast enough to outrun many standard predators, but Camouflage and Electric Discharge stop working while inside it. Leviathans can still aggro a Tadpole. Terrain is still your best defense in the vehicle.
