META-ALLOYS
Meta-Alloys are a special commodity in-game that can be used to unlock certain engineers, special modules and even fed to Thargoids. Here are a few different methods to collect Meta-Alloys.
Despite what some people say, Meta-Alloys are NOT CAUSTIC and will NOT deal damage to your ship if you carry them around. However, if you are scanned by a Thargoid Interceptor while carrying them, they may make some different noises, but ultimately they will not attack you.
Barnacles are the most common method to gathering Meta-Alloys, these can be found in 4 different regions of space.
The Pleiades Nebula
The Witch Head Nebula
The California Nebula
The Coalsack Nebula
