For Natural Selection 2 the team has talked about adding a female marine model, so I figured it would be a good opportunity to do a character concept and revisit some of the design elements from the concept I had done for the original game, that I was never happy with.
The 2 images below are possible variations for the helmet of the game models, to allow for some player customization. The one on the left is the full helmet, with a blue holographic HUD. On the right is the marine wearing just the basic computer/HUD module, with the idea that the additional armor plates that make up the helmet are snapped onto the base computer module. Since helmets are hot and uncomfortable, you often see soldiers in war films remove their helmets during lulls in combat. My concept was that the marines could snap off these armor plates in a similar fashion when they need a breather, or if they are just more of the "BadAss" type, and feel they don't need the full helmet.
