I can't stand using 2 clips to kill things. Are there mods to increase player bullet damage? And any that make headshots lethal to any creature? I found one mod that only handles humans, but I want everything to go down faster.

Ps. I know about Wander's edition but I want a small mod that just affects the things I'm asking about.

As you level up and increase your small guns skills, it will become easier to kill the creatures. Otherwise, check here: http://fallout3.nexusmods.com/.

I second the idea with a lethal shot. I think it is unrealistic that you - armed with the best and fanciest weapons, highly skilled in using these weapons, standing right in Front of your enemy - are not able to kill your enemy not with one single shot.

Something like this maybe http://fallout3.nexusmods.com/downloads/file.php?id=1814? (is that the one you found? says it works for all creatures) Fallout3Nexus is your friend
