| Property | Details | | :--- | :--- | | **Type** | Exterior Facilities | | **Category** | Power | | **Description** | Produces a steady trickle of power. Intended as a starter power source for new outposts. Unsafe for long term human exposure. | | **Fragments Required** | 2 |  -The **Radiothermal Generator**, also known as the **Oldfire RTG**, is a buildable seabase part.+The **Radiothermal Generator**, also known as the **Oldfire RTG**, is a buildable seabase part in Subnautica 2. It serves as an early-game power solution that does not require fuel or sunlight, making it ideal for initial outpost establishment. ## Usage -The Radiothermal Generator provides a continuous, low-level power output without requiring fuel or sunlight. It is designed primarily as a temporary power solution for new outposts until more robust power generation systems (such as Bioreactors or Thermal Plants) can be established. Due to radiation leakage, it must be placed outside the habitat and behind shielding to ensure crew safety.+The Radiothermal Generator provides a constant, low-level power output. Due to its radioactive nature, it is unsafe for human exposure and should be placed outside the habitat, preferably behind shielding. It is best used as a temporary power source until more efficient and safer generators (such as Bioreactors or Thermal Plants) can be constructed. ## Recipe -The blueprint for the Radiothermal Generator is unlocked by scanning two fragments found in the world. Once unlocked, it can be crafted using the Habitat Builder.+To craft the Radiothermal Generator, you must first unlock its blueprint by scanning **2 fragments**. Once unlocked, it can be built using the Habitat Builder with the following materials: | Ingredient | Quantity | | :--- | :--- | | Titanium | 2 | | Copper | 2 | | Tar Graphene | 3 | ## Fragments -Fragments for the Radiothermal Generator can be found in the **Tar Flats** biome. Below are known locations:+Fragments for the Radiothermal Generator can be found in the **Tar Flats** and surrounding areas.
