Metal Salvage (Subnautica)

Metal Salvage is a raw material found on the seabed.

In the Kelp Forest, it is picked up and gathered by Stalkers.

If the player holds one in his hand near a Stalker, it will pick it up from the player's hand, taming the Stalker in the process.

It can be found in the following Biomes:
 * Aurora
 * Blood Kelp Zone
 * Crash Zone
 * Dunes
 * Grassy Plateaus
 * Kelp Forest
 * Safe Shallows
 * Wrecks

It appears to be most common in the Crash Zone and Kelp Forest biomes, but the player takes a huge risk in visiting these biomes early-game.
