In Fallout New Vegas I built a sort of sneaky guy who'd travel in a sniper rifle and kill enemies stealthily from a distance, but I found this less satisfying. He had average intelligence and above-average charisma, but wasn't agile at all.
His companions would provide covering fire while he charged in. Originally posted by Das Boot:In Fallout 3 I built a big guy who favored melee weapons - first a super sledge and then later a ripper.
