This is one of those 3 page click through so you view more ads kind of things, and it's kinda long, so the tl;dr highlights I think are important are below. The article is still worth a read, these are just the most important things that weren't the author describing part of the video action.
- We see concept art of Mr. Handy floating around the family home as a door-to-door salesman talks to the wife and a high-res model of the robotic helper. "We don't just build the outside of the robots," Howard points out. "We build the insides so you can blow all of their pieces off.
- [...] Mr. Handy rattling off a variety of names, including Mr.Matthews, Mr. McFly, Mr. Boobies, and Mr. F---face. The last one brought a lengthy roar of laughter from the crowd. Howard smiles and says, "Now I wish I had shown the longer version of that video."
- We [...] see an image of a handful of Bethesda Game Works employees. On the floor is a German Shepherd named River, a female dog who was used for the motion capture and audio recording of Dogmeat. A video montage shows the various techniques the team used to capture River's likeness, including frisbee throwing in the motion capture studio, stick fetching, and holding a mic in front of River to capture her sounds. "If we're going to do the dog, we're going to do this right," Howard says.
- Dogmeat is one of a dozen companions in the game. Only one can travel with you at any given time.
- "We track how [each companion] feels about you," Howard says. "With the humans, it can even lead to romances and that is regardless of whatever gender you are playing. We spent a lot of time on this mechanic. They have a lot of personality. You can also play without a companion, and we have special perks for if you want to play as kind of a lone wanderer."
- Howard then transitions to the leveling system in the game. "We have a whole bunch of perks and those are tied to your S.P.E.C.I.A.L. stats. Every time you level up, you get to pick a perk," Howard says. An image of a poster with rows and rows of greyed out Vault Boys appears. When you pick a perk that you want, that greyed out Vault Boy animated and turns to color. The perks include intimidation, where you can control other people, attack dog, something called V.A.N.S., sneak, bloody mess, and dozens more. "You have this Vault Tech poster with all of your perks, and there is a separate perk for each S.P.E.C.I.A.L. and each value of that S.P.E.C.I.A.L. from 1 to 10," Howard adds. "Each perk, except for a few exceptions, has multiple ranks. We have combined the previous skill system into this as well. If there are 70 base perks and you add all of the ranks, you're getting around 275 of those. We've found that this gets us some really cool different play styles. It's a very very cool and fun leveling system in the game."
- Deeper in [...], we are given a brief look at safe cracking, lock picking (yes, bobby pins return), and terminal hacking. The terminal hacking sequence looked similar to Fallout 3's, where a player must decipher a scrambled sequence of letters, numbers, and characters.
