This gun has to main feels one being its futuristic green body with yellow energy tanks and the other being its not very well maintained feel of rusting metal. The gun is meant for practicality as it isn't very visually stimulating due to its bulky look.
Combat Armor from Fallout 3 and New Vegas. Gonna attempt to make this armor for Comicon next year. Either this or Fallout version of the armor, which might be more simplistic.
