I run into a lot of Deathclaws now that I have reached level 20 in Fallout 3. I really dread running into these things because of their lethal attacks. Everytime I run into one and kill it, I find my health nearly depleted. I have mainly been using the missile launcher to weaken them and the combat shotgun to finish them off. What do you all think is the most effective and easiest way to kill them without shedding so much ammo?
