How to get Axum Bacterial Culture in Subnautica 2
Axum Bacterial Culture is one of the rarest materials in Subnautica 2, required for crafting Metal Farms—devices that duplicate valuable metals and reduce the need for repeated resource gathering trips. The material is found in dangerous locations, including yellow metal fields and caves protected by hostile creatures. Players must first upgrade their Tadpole submarine with a Depth Module to access these deeper areas where Axum Bacterial Culture spawns. The resource is described as difficult to harvest and must be managed carefully; running low on reserves could prevent players from crafting the Metal Farms necessary for efficient resource multiplication. Specific locations include areas near Ruby’s second blackbox signal.
