Is Dogmeat the only companion?
Companion mechanics is great. It allows the game to be more entertaining. Having an NPC in your party is always good. Companion allows to complete quests and kill enemies faster.
From what I have seen in Fallout 4 related videos I know that there will be at least one companion: Dogmeat. It will follow you and you can command it. But will there be other followers / companions? Will it be possible to hire someone else? I like the dog but I would like to be able to hire a human :)
