So anyway. Made some progress. Guess what I made with 1396 Faces and 2792 Tris. Oh yeah, this suit. And the normals turned out good, so yeah, that's awesome.
7,688 Faces and 15,340 Tris
So here is the low poly mesh for the base armor. The Base Armor acts as exactly that, the basic set of equipment for the soldiers. On top of this goes an additional set of armor that define the specific class you choose as a player when you re-spawn. Like star wars battle front when you had different classes to pick from. same kind of idea here.
