Bounties and Dismemberment
We look at two Fallout 4 mods here: Bountiful Boards, and Live Dismemberment.
Bountiful Boards attempts to expand the bounty system, with three new bounty types, synths, gunners, and wildlife, along with a few other tweaks. I got one new bounty mission, one vanilla, and then nothing else.
Live Dismemberment gives you the ability to shoot limbs off and leave the opponent alive, if it still has the health to do so. Targeting limbs can now incapacitate a creature, but leave it alive as we can do in vanilla Fallout with ghouls. i like this one, it adds a new dimension to combat.
