Hello, I feel like the filter for the gas masks while making sense looks awful, so my simple suggestion is to make a respirator style gas mask to the point where it doesn’t cover your eyes, so you are safe from gas but can see as well.
Respirators have poor defense even against germs, let alone having any defense against gas that can (and will) kill you.
Also, the gas in the game doesn’t hurt you only when you breathe it in. It also hurts you when it comes in contact of your skin, making respirator style mask even worse since your eyes would be completely uncovered.
E.g think about tear gas. You don’t need to inhale tear gas for it to affect you.
Faor enough I didn’t think about that
