I'm hoping a mod does the same to Settlers. Though, there is a mod to make them mortal, Almost as good.

Do you realize how much ammo you'd need to keep your settlers supplied?... and then multiply that by up to 30 different settlements. It would be a nightmare.

I'm hoping the extra damage is EXTREME. Extreme as in a few hits and you're dead, headshots are instant deaths if not adequately covered up, and ample use of cover and and cover shooting mechanic is required. Deathclaws one hit kill moves proc no matter your health if you let them get close to you and the same goes for assaultrons, close proximity mini nukes = instant death aswell as mines et etc.

The high chance of death coupled with enemies not showing on the compass will make things so much more tense, adding to the atmosphere.

Perhaps. But I like it better than Only Save On Sleep.
