Permanent companions usually have prerequisites and may not join your party unless certain conditions are met; these vary between potential companion NPCs and often there are multiple possible ways to obtain them as a party member. The game will not allow having more than a certain number of active party members; this limit is half the player character's Charisma, rounded down. For example, a Charisma level of 4 allows taking 2 companions. With the perk Magnetic Personality the Chosen One is allowed one additional companion over the current limit.

Once a non-player character is recruited, their dialogue menu changes to a list of tactical and combat-oriented options. New from Fallout is a "Combat Control" button in dialogue, which allows manual change of an non-player character's armor, weapon, distance and tactics.
The picture to the right is the in-game dialogue box for controlling companions. For permanent companions, the options are shown as follows:
Use Best Weapon
- At first, this seems to do nothing, because the companion originally only carry their default weapon. However, they can be gifted a better weapon (and ammunition, for guns), then the non-player character will make use of that weapon instead. Alternatively, the companion can pick up weapons found on the ground.
Use Best Armor
- Berserk - The companion will always attack, never fleeing from battle, no matter the level their health drops to.
- Aggressive - The companion will attack while their health is in an acceptably decent range. If it falls too low, they will ultimately flee from combat.
- Defensive - The companion will be more mindful of their health, running when they are injured, even if just slightly.
- Coward - The companion will always run from a battle they think they cannot handle, regardless of the opponents.
- Custom - There are six options with 5 sub-options that can be chosen concerning the non-player character's disposition. The possible options for each is listed below.

At numerous occasions throughout the game, the Chosen One may find their companions blocking the exit to a room. This problem can be solved by entering the companions combat controls and changing their distance to the player character, followed by entering combat, thus having them move away from the exit. More easily they can be right-clicked on and pushed away through the corresponding action.
Sometimes while following combat, companions may get stuck, and are unable to speak, move or fight. While in this state, they can be looted, and join the player character during fast travel. There is no known fix.[verification overdue]
