Yeah, I kind of do. The Vault Dweller at the end of the trailer is either THE guy, or his kid. http://imageshack.com/a/img540/4378/YSGU4f.jpg

Even if they somehow survived the blast wave from a near nuclear explosion how did they then get in a sealed vault, did any Vault in Fallout lore ever open its door immediately after the nuclear war began to let in survivors?

It start showing a dilapidated house and flashes back to what it looked like 200 years earlier with a happy family, then it show panicked people trying to get into a vault and then some people (from my repeated viewing including the happy family) dying locked out of a sealed vault.

Then you see the dog which has no link to the old family, expect for some house the dog was exploring having a dog bowl in it 200 years earlier, greeting another guy walking along a road 200 years later and thats pretty much it.

There is very little there to hang the theory on.

Who said it was sealed. Looks like they are on there way in. Many of the people are stopped at the gate, crying but the family isn't. They are at the door. I just believe the dog acts as a hook to follow the man in the trailer life's events.

Considering that that would make the Vault useless aka letting all the Radiation in?

I personally think

Its shown to be sealed, the people are actually standing on the sealed entrance, its open when the dog gets to it.

Also this is not the entrance to the vault because we have seen that in the trailers, so those poor soals died without even making it to the main entrance of vault 111.

Kinda my point, if the family is there when the nuke explode outside they are dead or ghouls.

The dog is post war. There is a scientist with a clip board, guards and a ton of luggage there, so no it doesn't have to be sealed.

The Vault has two dors one that works like a Elevator and one that is down inside.Te Elevator door is closed whenver it's up.

And nobody with a brain would let it down again after the bomb dropped.

About the video:The bomb dropped much closer ,and they were hit by the debris.

I'm not sure any of it was significant, but saying it was perhaps the baby was protected from the radiation by it's parents bodys and drug into the vault by the dog just before the door closed and we just haven't seen that part. Then he was frozen, aged slowly and maybe even developed some unique trait due to the small amount of radiation he received in those few moments. Maybe the dog made it too and he was frozen as well as everyone who made it into that vault.

It was programmed to awaken them in however many years. Maybe they didn't even age during that time. All sorts of strange experimental vaults throughout the wasteland.

Ok, well...that's my story and I'm sticking to it until we get some real details.

All of whom would have to be inside before the nukes hit otherwise they wouldn't be getting in either and we actually see that the shaft down to the vault is sealed because we see people standing on it when the nuke hits.

No, because you see him next to the wife when the bomb goes off. http://i.imgur.com/lUKbl24.jpg

The video you (or I think it's you) linked isn't definite proof. 1) The bomb is much closer in the trailer and 2) We have no way of knowing if they're the same yield. A small Hiroshima-type bomb? They're fine. A Tsar-class bomb? Not even ashes left at twice the distance away.

Or maybe it's the dad.

/Occam's Razor

BEFORE Bethesda came, Vaults were made to test how humans would do in certain enviromental conditions. Necropolis was about how would people react to being exposed to Radiation, how would the people outside react, how would the population change.

AFTER Bethesda, Vaults are.. random.

Your assuming this is your standard vault. There may be essential people and their families this vault was made for and they will get in radiation or not. You explode Megaton in 3, you didnt die or turn ghoul

To be fair, Avellone basically made the "lolsorandom" Vaults first in the Fallout bible, which Bethesda used.

"I" was on a Tower a long distance away.

That's not accurate. Vaults got screwed up with stupid, nonsensical experiments well before Bethesda entered the picture. On the oil platform in FO2, you can discover that the vaults are all sinister experiments, and the Fallout Bible published by the original Fallout team listed tons of stupid vault experiments.

Honestly, I wish they had just kept the vaults' purpose to SAVE people, like in Fallout 1, but in Fallout 2 they felt they needed a stupid twist to show how mustache twirling evil the Enclave and the government were.

If they were essential people they would have been in the vertibird not running for their lives. You paid for the privilege to be one of those allowed into a vault, they were refugees not essential people anybody who was essential to a vaults operation would already be in the vault getting it ready for the influx of new vault dwellers.

The real essential people were in the Enclave vaults not standing on sealed entrance out in the open to be hit by a blast wave second after a nuke explodes in their faces.

The point of the Vaults is that no radiation got into them unless they failed, otherwise vault dwellers would be ghouls and the Megaton point is just silly, your right across the map when it goes off.

Ok well I will pay for your copy of FO4 if your right, but your not. It is the same guy.

It does beg the questions...

How he survived the blast?

How would he get in the vault?

I think people are missing the point of the trailer, its not showning you the story. It is as much to introduce new people to the game as anything, I look at it this way...

There was a nuclear war = check

Some people survived by going into underground vaults = check

Others were abandoned to die outside the vault doors = check

Look at some of the cool people, places and things in the game = check

Thats you exiting the Vault = check

Thats you heading out on your adventures = check

Cyrogenics isn't mentioned or even vaguely hinted at.
