Fallout: The Traveler/Companions

Returning from the previous games, now combined with elements from the popular Fallout New Vegas mod JIP Companions Command and Control. The Outer Worlds and the Character system from Genshin Impact albeit cut down. Companions played a much bigger role in Fallout The Traveler. They can be found all over the wasteland and depending on the reputation on the faction you are, your profession given at the start, all has Paimon Pip entry, equipable with a specific Weapon, skills that are skilled at, and belong to both Wanderlusters (independents) and Faction aligned. On normal gameplay, they're all essential, so they cannot die unless if playing on Sawyer Mode or Immersion Mode.

How to Obtain
Companions are primarily obtained by exploring around the Wasteland and depending when you have good reputation with that faction, your profession given at the start and your karma standing. There are two types of Companions: Wanderluster and Faction Affilated. Wanderluster companions can be recruited regardless of reputation or Karma and Faction affilated companions are can be only recruited if the Traveler has positive reputation with that faction.

The Companion Ledger
The Companion Ledger at Paimon Pip shows you everything you need to know about your companions. You can see their skills, stats, status effects, perks, and gear. In conjunction with gear, you can select and swap the compatible weapon and armor for your companion. On top of that, players can also change the companion's behavior in combat such as their distance, preferred weapon, and aggressiveness.

Focus Fire
Select your companion and press the up button on the controller's D-pad once to order your companions to attack on V.A.T.S.

Affinity
Companions can develop personal connections to the Traveler and most of it may ask for help with quests of their own. Each companion has a distinct personality and values. Actions or dialogue that please one companion may displease another.

Raising the affinity value grants additional dialogue into their history or the possibility of romance. Reaching maximum affinity with a companion will unlock a special perk. The affinity value is a hidden statistic, meaning it is not possible to check the progress without console commands.

Leveling
Characters gain experience primarily in combat.
