If it's 2277, It can't be Lyon's BOS as they had their hands full with the Enclave in DC then, which could also mean the Enclave could or should have a presence in Fallout 4 somewhere, maybe!

I think it's partly so they don't have to give away more of the new factions. Use an established faction in the trailer (as well as one that shows off things like vertibirds and whatnot) so that the trailer isn't just PC shooting raiders and animals. Though we did get to see synths in the trailer too. Wonder if they're a faction or just more wandering robots to fight.

Neither. IMO, the end of NV didn't ultimately decide that. No matter who won at the end of NV, the whole thing is doomed to repeat itself after 5-10 years maybe. Dam's too important and after all (*chorus*: ) war never changes.

^this

There are supposed to be at least two Android factions:

1. Synth Retention Bureau (which hunts synths who escaped Commonwealth) or some other faction loyal to the their creators, the Commonwealth and the Institute

2. The Railroad - the faction that fights to free the Synth from their Commonwealth slavemasters

It is also highly likely that a proper Synth Rebellion had occurred, as suggested by Harkness way back in FO3.

I doubt the Legion can really survive losing to any faction, particularly if you activate the Securitrons in the bunker and defeat Lanius in battle. At that point the entire chain of command would appear to have been severed. Caesar dead, The Legate dead, the head of the praetorian guard dead, and the head of the Frumentarii dead. The only way the fifth person in the chain of command would still be alive is if he wasn't at the Battle of Hoover Dam, which is unlikely to be the case given its pretty much a nomadic tribe of raiders at the moment.

NCR vs Courier Six or House I can see, but I think if the Legion loses, it's gone.

You're probably right. It won't be the Legion we saw from NV. But then there'll be a huge power vacuum. Those tend to be filled, so something else will emerge sometime. Probably.

Anyway, this is quite OT, sorry.

except the enemy health bar at the top blatantly saying it was a brotherhood member.

The Brotherhood Outcasts never recovered any Enclave tech. Certainly not Vertibirds or Eyebots. Lyon's East Coast Brotherhood did recover Enclave tech. The Midwestern BoS is known to have used Airships in the past, and if they have Vault 0, they most likely have the tech and means to produce Eyebots and Vertibirds (not to mention the Hellion) as well.

We do know the guy in the Vertibird was BoS, due to the fact that the health bar flat out said "Brotherhood Initiate".

You guys see how the main char shot a rocket launcher at a Brotherhood Initiate on a bridge, and while it blew off pieces of his Power Armor, it didn't actually do alot of damage?

Isnt this before the events of the lone wanderer?

Who knows but I sure hope it is MWBoS.

Nope.

They just gave a generalized 200 years after the war figure.

Its Lyons, the airship is named after a boat in Arthurian legend which Lyons boS was based off of.

about the same time. 2277. Could start a few months before or after, but same time zone

It could be 10 -1 5 years after honestly.

Human speech frequently reduces numbers like 634 years ago down to just 600 for the ease of saying it.

So it would seem that they really did intend for Arthur to be the literal "King Arthur of the Brotherhood." Let me guess they built the airships to travel back to the West but a storm came and sent them to Boston.

That or in a few short years they became a super power because Magic and now have airships and a fleet of Verts and want to expand into Boston.

Except we also have a robot saying that the Sole Survivor was missing for 200 years. So , yeah 2277 is the most likely date, and that puts the events of FO4 around the same time that the events of FO3 were happening.

Interesting. If that is the case then it would be the MWBoS.

Again, the robot would just say that for the sake of shortening it.

They likely captured a ton of vertibirds from the Enclave at Adams Airforce Base. They did say they were going through everything the Enclave had, which was A LOT.

Enclave weren't the only ones with Vertibirds. You're in MIT territory, I'd wager they had a massive hand in developing them, so it stands to reason that there would be a few around (MIT use them) or the knowledge to build some.

BoS may have taken them from MIT or just found how to build them.

The MWBoS also have a fairly large area, they may have found a reverse engineered some (If it's the MWBoS we see)

Lyon's BoS of course has Enclave loot.

I think it's the MWBoS because in Fallout 3, there is no mention of them having a presence anywhere else. And even given a few years after, I don't see them having enough of a force to really do anything in Boston (remember they were in DC for a while and didn't accomplish much, even before the Enclave started making moves)

Its very likely that the defeat of the Enclave, the breaking of the super mutant threat, the destruction of the Talon company, and the control of the water purifier could have easily swelled Lyon's Ranks fairly quickly, and with all the hordes of Enclave tech they could have pulled out of Raven Rock and Adams, equipping people shouldn't be that hard either.

The airship is called the Prydwen, the name of king Arthur's ship. Guess Americans can't spot Welsh. My guess is that the game is set when Artur Maxson is an advlt so at least 10 years.

Also concept art shows dudes in BoS marked t45d in Vertibirds. So yeah, Lyons BoS it is IMO.

Edit: also MIT is not a factory. They wouldn't have tonnes of armed gunships on campus

Fair point, didn't notice the name.

I should have clarified that I meant MIT may have had a prototype and plenty of blue-prints for them around. After the war, the Institute may have built a few to assert control over their turf.

If it is Lyon's BoS, but under Arthur, he may have decided to return to the BoS original purpose. Saw that Boston was home to a technological superpower (The Institute) and decided to take them out? After all, only they are allowed cool techno-toys.

As long as they aren't the White Knights they were in 3 (which judging by you fighting them in the trailer, I'd say they CAN be the enemy), I'm happy.

EDIT: Could also be that they ARE the White Knights and don't like MIT's oppression of the surrounding area (Fallout 3 made it seem that they were not a nice bunch). Either way, I hope they are both factions you can join. ALL hail MIT

*I use MIT and Institute interchangeably

I think it's almost certainly Lyon's/Maxsons Brotherhood.

I think it will be a NV style choice between the two, some of the concept art shows the 111 Dweller fighting alongside BoS, not to mention calling in the Vertibird landing in the game and some concept art shows you firing the from the side.

As long as you can get the option to use this Vertibird feature with the Institute or just outside the BoS I'll happy. The Brotherhood of Steel in this game are all going to die, every Vertibird in-use represents dead Enclave... which means everything connected to them will be killed by me.

Interesting. Maybe we'll bump into Madison Li on her way to the Commonwealth from Fallout 3.

Yup. I feel they're defeat in Fallout 3 was a joke (I'm ignoring that they really shouldn't have been there in the first place). They had (in game) more men, better tech, air superiority, and an orbital weapon pointed at the pentagon. Without the god-like Lone Wanderer, the BoS would have lost (IMO, but this isn't the place to really get into it).

Every single BoS I see will be destroyed for what they did. RETRIBUTION!

(If you couldn't tell, I love the Enclave)

It's a Mister Handy. They don't are exact on the date, because they act more... human. So if he says 'You are 200 years to late' he means 'You are circa 200 years to late I don't use the exact year, because no human would like if you say 'You are 287 years, 17 days, 11 hours, 14 minutes and 44 Seconds too late'.
