T3 Industry
The mechanics in T3 Industry are very similar to those of T2 Industry. However, the required materials come from different places (Wormholes) and different Skills are required in the process.
In general, gas from Wormhole sites is combined with minerals and turned into Polymers to make the required special materials.
The blueprints come from invention on Ancient Relics that are also found in Wormhole Space. The mechanics are pretty much exactly the same that i’ve explained in invention, stuff just has different names and comes from different places.
