I am a huge fan of Fallout 4, but the companions in the game leave a lot to be desired in my book. I find most of them to be more of a hindrance than a help, they always block doors or walk into my line of fire like morons. I've played mostly with Paladin Danse since he can actually fight if you need to. The problem is he isn't very stealthy leaving you basically unable to sneak up on people, especially if your power armor has the stealth boy mod. A new mod for the game has been unveiled, and it lets you play the game as one of the companions, specifically the cute and ferocious Dogmeat.
