For the human companions, the options are shown as follows: There are no controls whatsoever for Dogmeat. This means that in Fallout, the controls are rudimentary, at best. Unlike Fallout 2 there is no "Combat Control" menu added to the Pip-Boy interface. Once an NPC becomes a companion, their dialogue menu changes to a list of tactical and combat-oriented options. Tycho ( Junktown) - Completed the quest to save Killian Darkwater's life and inform Tycho about it, the former must be alive.Ian ( Shady Sands) - Convince him to tag along with a Speech check, or give him 100 bottle caps.Dogmeat ( Junktown) - Either Vault Dweller is wearing a leather jacket or by giving Dogmeat some iguana bits or iguana-on-a-stick.Their locations are listed next to their names.

The possible conditions that must be met for each companion are listed below their names.

For a few NPCs, there is more than one possible way to have them join. Permanent companions require that a few requisites be met in order for them to join the player's party.
