I used open face helms for the Skyrim guards.
First off, I don't know why Bethesda makes the guards faceless in their games. They are people too. In my opinion its kinda immersion braking to see the guards in full head covering masks. I wouldn't take that job if I had to have stuff allover my head like that.
All I'm askin for is a mod that removes the guard helms. I'd say that should be easy, but I don't know. I don't make mods.
Good luck and thanks if this gets made. If it does, someone please shoot me a message. I'd like to use it.
