Ive suggested once before that aliens/human armors should get some neat-o screen overlays or somthing similar depending on who they are.
For instance, the dretch has a wider field of view. But why dont any other aliens have "different" FOV's compaired to humans (or other aliens)? After all, most of the aliens do in fact have eyes on the sides of the head and not infront of the head like humans do. Also, I mentioned before on how it would be neat if everything the aliens saw had a blueish tint (or somthing similar) to it, seeing as they wouldnt have normal human eyes. Its just an immersion thing.
Also, i suggested that a helmit could have more of a "FOV blocking" effect to it (such as, you can see the sides of the helmit on your HUD), making it so having no helmit at all isnt nessicarily completly dis-advantagious, as you will have more view of the battlefield.
Similarly to the Bsuit. Seeing as the Bsuit is just a camera for the head, why do they have completly normal FOV and vision when you equip one?
It would be awsome if when you had a Bsuit you would have a camera-effect go over the HUD, and mabey a smaller FOV to go with it.
