Fallout 4 Guide: List of all companions, their perks and where to recruit them

I can only imagine that waking up after 200 years to a world that is now decrepit and and destroyed, you're going to feel scared, lonely and unsure of what to do next. Well, good news is, you don't have to trek it alone.

Fallout 4 features a bunch of companions that are willing to join up and help you survive the harsh environments and hordes of horrifying mutations. There are 12 companions in total, and 11 of them have a special Perk that you'll get once you reach maximum affinity with them.
