The wastelands of Fallout 4 are a dangerous and lonely place to wander in. The enemies in this game are more fierce than ever before, and some players may find themselves overwhelmed as they explore on their lonesome. If players don't opt for the Lone Wanderer perk and get terrified at night by lurking ghouls and other critters, having a companion tag along might be a good option. It's a great way for players to enjoy some much-needed companionship during the game's lengthy run time and also form a great bond with the many followers the Sole Survivor can recruit.
