Of course, I don't thinkg I'm good enough to model the large chest armor below the equuiptment boxes (you can barely see it anyway), but I might try the equiptment. (You can see the bar and antennae (spelling?) behind him).
I'm guessing the line drawing to the left is part of the backpack. I know this is a concept drawing, but is this reference accurate enough to the real game that I should model off of it? There seems to be a bit of a lack of reference. I used that picture as a reference for the sniper shields, but I forgot I could use it for the chest/backpack.
