Where to find the antidote for the Kharaa bacterium in Subnautica: Below Zero

Subnautica: Below Zero isn't just a game where players traverse the sea, as it has incredible story aspects.

One of those story aspects involves the main character's sister, Sam Ayou. Players venture through Subnautica: Below Zero as Robin Ayou and have a goal of discovering what happened to Sam.

While things are left up to the Subnautica: Below Zero player, an antidote for the Kharaa bacterium can be obtained. This antidote can be used to cure the Frozen Leviathan.

The Kharaa bacterium is something Alterra Corporation and the Architects have been studying for what seems like ages. Of course, not everyone has the same goal when it comes to the bacterium.

An antidote is available and players can use it to complete the dying wish of their in-game sister, Sam. That simply requires finding the antidote and using it to decontaminate the Frozen Leviathan.

The antidote for the Kharaa bacterium isn't too far off from where the Frozen Leviathan is found in Subnautica: Below Zero. You need to head to the Glacial Basin Biome and then follow the steps mentioned below.

• To obtain the Kharaa Bacterium antidote, visit the main area in front of the Phi Robotics Centre to kick off your journey.
• Board your Snowfox and make your way through the icy valley to the west.
• You’ll come across a Stalker nest. Don’t engage this creature; just loop around.
• Continue on the snowy path till you come across a large open area with a lot of structures and some Penglings and Snow Stalkers.
• Look for the cave that has a box placed right beside the entrance.
• Since the cave is small, you will have to use your Spy Pengling to grab the Kharaa Bacterium Antidote from another box inside the cave. You can also obtain the blueprint this way.

Only one is needed to complete the objective of curing the Frozen Leviathan. If, for some reason, it gets destroyed or lost, the blueprint allows it to be crafted in the Fabricator with one Frost Vase Plant and one Fever Pepper.

In case you’re having trouble finding the cave, the video below should help you figure out the exact location. You may also just prefer watching the quest playthrough before attempting it.
