Complete Subnautica 2 Biomods tier list
We can have only one Active Biomod at any given time, but the same doesn’t apply to the Passive ones. I have used three different tiers to judge each of them based on their abilities.
- S-tier choices are pretty much the best options.
- A-tier choices are good, but you’ll need to time their use.
- B-tier choices aren’t my favorites. They get the job done, but they’re extremely situational.
S-tier
| Name | Effect | Reason |
|---|---|---|
| Dash | Dash in any direction to avoid predators or hazards | This is one of the best active Biomods, and it’s free. You can use the dash to avoid enemies or cover distances quickly. The cooldown is short, adding to its usefulness. |
| Sonic Echo | Emit a sonar pulse to highlight nearby resources | Finding deep resources is not the easiest task. Hence, knowing their location is certainly beneficial. |
| Camouflage | Become invisible to predators when not moving | If you find yourself trapped, all you have to do is stay calm. However, you can still take damage if the predator accidentally hits you. |
| Homing Sense | Detect nearby bases with electrical power | Great at finding nearby bases if they have their power source active. |
| Dermal Garden | Slowly grow nutritious algae on your skin | This is a useful way to manage your hunger in desperate situations. I also don’t like to cook, which is partly why I find this Biomod to be so beneficial. |
A-tier
| Name | Effect | Reason |
|---|---|---|
| Electric Discharge | Emit an 800-volt electric shock to deter medium and large predators | This charge is enough to deter any incoming predator and send them packing. However, don’t try this with the Leviathan (I did, and the results weren’t pretty). |
| Chum Cloud | Release a cloud of delicious bait to distract predators | This is a good alternative to Electric Discharge, and it allows you to get away when being chased by a predator. |
| Oxygen Control | Slows oxygen consumption when not moving | Consuming less oxygen when you’re stationary is useful, but having a bigger Oxygen tank is better. |
| Bioluminiscence | Glow in the dark | This is beneficial if you love to explore at night and don’t want to carry the Flashlight with you. |
| Threat Sense | Detect nearby threats with specialised hair cells | There are ample times when a predator will be lurking around from a blind spot. Threat Sense also alerts you about hazardous environmental conditions. |
| Water Retention | Gain more water from all sources with enlarged, orca-like kidneys | Since your body absorbs more water from practically any source, you can pay less attention to your thirst. |
B-tier
| Biomod | Effect | Reason |
|---|---|---|
| Pathfinder | Release a trail of pheromones you can follow to find your way | While the pheromones do prevent you from getting lost, their usefulness drops as you unlock more advanced tools. |
| Sea Skimmer | Swim faster when close to underwater surfaces or the seafloor | While the enhanced speed is noticeable, you can easily replace them with tools like the Wakemaker. You’ll also travel in the Tadpole once you’ve unlocked it. |
| Water Secretion | Slowly fills a water packet by filtering fresh water from the sea | Allows you to passively regenerate water, but go for Water Retention as that’s a better choice. |
The only Biomod I have yet to assess is Slow Metabolism (yet to be unlocked). The list of available options should increase during early access once the updates are dropped. I will duly update my tier list accordingly based on how the new Biomods fare compared to the existing ones.
