Will there be a option to not wear a helment for space marines, that you can create a characters face. Kinda like skyrim, mass effect just not in super detail but you get the point. Giving a option having a terminator half face, bionic eye, hoods, crazy hair do etc.

Some face customization has been discussed, we're not sure the extent but yes it is to be a thing. As well as the ability to not wear a helmet. The devs thoughts on the matter last I heard was that not wearing a helmet could cause a small boon, a sort of inspiration factor for your squad, but for at the cost of taking more damage from headshots, given that you've left your noggin exposed, unarmored and whatnot.

I imagine to have heard Brent mentioning that there will be an option to run around without helmet, but I really cannot find the comment anymore...

It might have been a Stream.

Here you go:

10. Will we ever see a face designer for each faction and following that be able to equip and unequip a helmet?

BRENT ELLISON: Helmet-less characters are still planned but won’t be present for the initial Founder Access.

You will always have the option of getting shot in the face

you won't have to worry about that

There's also this,

Q: [51:52] Can you give any information on Character creation?
A: You will have a no-helmet option and be able to pick a head.

Honestly while a helmet-less option would be cool, I definitely don't want to see tons of people running around playing as their own captain hairspray.

just because its an option doesnt mean everyone will choose that option ... more choices is always a good thing though

Thanks for finding the questions. I just wanted to see if there is a option for it. I mean if there is going to be RPG element in the game, I would like to know what my character will look like. There is so many pictures in the 40k Lore of showing space marines in command positions being helmentless. You know there is force fields that help them not to worry about getting head shots. Just having the option is good, giving the player to invest in his character even more.
