How are the shapes? Main influences I can see are Shinkawa Yoji's angular shapes, Armored Core's V shaped chest, and a bit of Appleseed? The scratched up paintjob is definitely something I got from Starcraft 2, though.
I'll scrap this later, or update it with a more finished concept.
That grenade launcher is just filler for now, I'll make a real design later on. I didn't think too much about the armaments for now.
This design is supposed to be the most basic and generic for a suite of similar designs from various factions.

NO, IT'S NOT FIST-PUMPING! Hahaha!
