aka...frigates, crates, walls, barriers, elite armor, shoes, etc...
The reason why I ask this is not to give bungie a hard way to go, but to figure out what material they use since they have no relativity to earths natural resources like metal, tin, aluminum, steel, iron and other matter. I just find it strange that no one else asked this question before. I mean...bungie obviously had something in mind to name it...right? So if a Bungie employee is looking at this please tell me...ive been wanting to know this for a while now...and yes, I will loose sleep over it
