Favorite guns? Cant go wrong with All-American and Survivalist Rifle. Good at close/mid range, decent damage, decent fire rate and plenty of ammo. As
@Friendly Primarina said, hunting shotgun is GOATED. get the perk that makes enemies fall down when getting shot. Any Deathclew trying to get close will fall on its ass before they can reach you.
As for energy weapons, i always liked Tri-Beam Laser. stack that with any crit bonus you can find and fire at close range, most things will turn to ash in a second.
