Such great foreshadowing. "You are the prophet and the prophet is you" at first sounds like the type of inane, metaphorical slogan you would expect a bunch of brainwashed cultists to repeat to each other as a mantra. "Yeah, sure... I am the prophet and the prophet is me..... whatever you say crazy lady". It's a cliche that fits so perfectly in-game that when you first hear it you don't even think twice. But by the end of the story you realize that, no, this is *literally* true. I am actually the prophet and the prophet is actually me. Bioshock Infinite is filled with story spoilers like this which are so brilliantly hidden in plain sight that you don't even notice them until repeat playthroughs.

And so it ends where it all started. Under the water.

This ending seems to make a bit more sense after seeing for the tenth time.

Well here we are, recalling this masterpiece once again.

In comparison to Bioshock 1, Infinite wasn’t nearly as strong, but it had its moments - this entire sequence was one of those moments. Experiencing it all for the first time was... incredible and tragic. To find out Elizabeth was your daughter, to find out the truth and to die in the end to make sure the realities with Comstock never existed - to make sure Elizabeth, your daughter, never suffered again.

The Game is just perfect! I have NEVER expected an ending like THAT! All the time i thought booker and elisabeth would have made such an awesome couple after all what happened and than THAT! I was shocked at first...and than i lost tears. The end is so touching and so sad...man i LOVE this Game SO much! PLEASE make another one :D And sorry for my bad english :)

when I realized I was in rapture I damn near shit my pants out of excitement

If any of you guys are actual Bioshock fans , then you would notice that at 1:12 when booker turns around , you can see the glowing sign "Rapture Metro" , the creators took a quick flashback to Bioshock 2 where the setting takes place in an under water city named Rapture

The songbird bit.. Hits me right in the feels.. A grown man crying over a mechanical bird!

Amazing game, just finished it (didn't have the time to play games since 2009); I disagree with the interpretation, though. Booker didn't fully die, because he became a father only after the battle of Wounded Knee and baptism offer. He was sort of reduced to the non-baptised version without the experience of selling Anna. Essentially, 20 years of his life - which in our case culminated in meeting Elisabeth - were cancelled, but I believe that the player-Booker and the ending-Booker are from the same timeline. I think he was given a second chance at life, and the best one. Elizabeth's explanations were for EVERY Booker in possibility space, she used the consciousness of having-met-her-Bookers to convince the wavering Bookers who would otherwise go through with baptism. So in the end we see the true Booker awakening in his past, with memories of "his" death, but it's really like with the Columbian soldiers, they see memories of their alternate versions who died. Besides, we can be confident that Anna's safe in the crib because there's no Comstock in the edited multiverse to "buy" her. That's all.

This is IMO one of the best mindscrew endings in gaming history. After playing around with temporal distortions galore throughout the game (and especially for the last half of it), in the end you end up unwinding and collapsing all possible universes... except _one_.

Can we just talk about the music for a second? It’s bloody fantastic,

Truly one of the greatest moments in games

And it was at this time Ken Levine decided to spark one of the greatest BioShock controversies of 2013...or of all time in that case. Or does the biggest BioShock controversy come from something else? I mean, the possibilities ARE infinite......;)

Anybody that's played To the Moon will find the Stars/Lighthouse thingy even more touching.

this story does not get out of my head even 6 months after playing the game....just brilliant

I almost cried at the end :') nice to see everything works out and booker can raise Anna as her daughter. And there's only one og him now in a universe where Comstock never existed and where he don't have any debt

One of the best games I have ever played. The ending just gave me tingles. I still think feel it. It was an amazing game.

That goddamn piano at the end. . . the most painful thing to listen to. . .

I remember when I first played this at the time, my jaw dropped when they came back to Rapture.

this was FUCKING AWESOME!

one of the best games of all time

I've seen this several times now, but it still gets me almost as much as when I saw it for the very first time. From the orchestration, to the pacing, to the voice acting it's just a mind blowing experience. This really raises the bar in videogame storytelling...hopefully.

I've play all of the Bioshock games ALOT and by far this is the best game I have ever played in my life... The ending is by far amazing.. It made me wanna cry

Greatest game ever! Mind=blown

2:10 That has got to be one of the dumbest things I've ever heard.

This was refreshing, no matter what choice you make in the game the ending will be the same, different Bookers from different universes who are all similar, yet different, but end up with the same fate. Even if you did not take the baptism, he would of still ended up the same as he is now. This was really an amazing game.

I think the beginning quote is referring to the memories of Robert Lutece offering Booker to go to Colombia where he recreated some part of the memories using the memories he had when he was selling his daughter to Lutece earlier

I really enjoyed this game, the ending was amazing!

Ok in short, Booker Dewitt goes to the baptism and reality splits in two at that point, one line is where he becomes Comstock and accepts the baptism and another where he refuses and becomes booker. Now in comstock's world he works with the Lutece twins (the people in the boat), who are scientists or something, and they know how to move between lines. It is at this time that Comstock is building Columbia, and realizes he needs a daughter, but he has become infertile for some reason I can't remember, so with the lutece twins, he jumps into Booker's line and takes Anna or Elizabeth (same person) and the tear closes on her finger, which is why she is missing it. Comstock eventually has some sort of falling out with the twins, and in order to stop him, they bring Booker from his line through a tear, into Comstock's (the one with Columbia).

When I played Infinite for the first time I was absolutely not expecting this. I usually skip the credits at the end of games, but I just had to sit there and try to make sense of what had just happened.

The intro versus the ending make it seem like a parallel too, entering Columbia you ascend and then descend, leaving Rapture you descend to ascend plus the two lighthouses.

First of all there's no Final Boss. No reason that should be in the title. Secondly, I'm certain I'll be burned at the stake for this but I feel the downfall of this game was the fact that it relied far too much on plot twists over actual plot. I find it funny how most people who criticize this game or its ending get talked down too as if they're intellectually lesser for forming an opinion. Yes I did understand the ending and the idea of infinite universes but I found they had difficulty co-existing with the human element of the game. The first bioshock was about a city absent of rules or god that fell to its own corruption. You feel for the denizens of Rapture because while being the pinnacle of science and industry they were all just regular people at one point. I never get anything close to a feeling of sympathy for any of Columbia. Elizabeth drew me in at first but when faced with the scale of infinite universes it's hard to... care. Nothing matters, the city doesn't exist anymore and it becomes less a story about people and more a bunch of bad comic book twists. The ending is complicated but nothing is really gained from its complications. The plot twist is there only because the other bioshock had a plot twist.

While the city is an important part of the game, the story of the game is more about Booker/Comstock and Elizabeth/Anna more than it is about Columbia. "There's always a lighthouse, there's always a man, there's always a city." I don't think you're suppose to feel any sympathy for Columbia, but you are suppose to for the characters I mentioned. Narrowing this story down to these two characters, every Elizabeth (not Annas) that exist, exists because of that decision to be baptized, and every timeline that begins with a man going to a lighthouse to get to a city ends with the prophecy of the seed raining down fire, on New York as the scenario in game shows, but it's not so much about saving New York as it is about stopping Elizabeth from being the one to do it, and I'd imagine it isn't the only "bad future" that the Lucentes are trying to prevent, but it is the only one we're presented with in the story of the game. The split between Booker and Comstock happened at the baptism, so killnig Booker before he can make that decision would ultimately get rid of an Elizabeth that would eventually be able to tear holes through spacetime, and thus end their story. It might not be cathartic, but it definitely is an end, and I don't think the game is trying to say the world is saved at the end,, or that there won't be a Columbia, but Booker's and Elizabeth's are definitely over. As far as your criticism about relying on plot twists, the first Bioshock was basically an FPS slog to get to the fanatical leader of a city you're in with a plot twist that "Surprise! You were predestined to go there and kill him!" and then it turned into another slog to get to the real bad guy, whereas in Infinite, it's you trying to get to the fanatical leader of a city you're in with a plot twist of "Surprise! You were the bad guy the whole time!" The only difference is the timing of the reveal, which I think all of the subtle foreshadowing in Infinite handled much better than the simple reveal of "Hey, all those 'Would you kindly...?"'s meant you had no choice. I think Bioshock 1/2 were more about the world with a plot twist about the characters, whereas Bioshock Infinite was more a story about characters with a plot twist about the world.

Huh, why couldn't they leave it all in the past? Leave the pain and tragedy behind them and move on? A million other awful things happen to other people across the world, worlds and they don't go out stopping things from ever happening. Why not accept some other Elizabeths and Bookers don't get happy endings?

@braxtonanderson277

Thomas Parkin They wanted to make sure that everything that happened in Columbia, never happened. None of the murder, none of the segregation, none of it. However, they had to "stop it where it all began" aka the baptism. You see, this is the turning point in the story. Booker can walk one of two paths. In one universe he accepts the baptism and becomes Zachary comstock. In the other, he rejects and stays as booker Dewitt. If they wanted to stop all the Columbia stuff, they had to go back to the turning point. Had they gone back any further and killed booker, then Elizabeth wouldn't have been born, which means none of this could ever happen. I know, parallel universe stuff, it's confusing.

12:54 Look closely. Elizabeth doesn't follow Booker through the door. None of the Elizabeth's he sees have the neck pendant.

Sometimes I imagine that there's another person with Booker and Elizabeth(s) to prevent Comstock from being born and for Booker to become Jack in the world of Rapture.

The best 15 Minutes of my Life! Completely mindblown when i first experienced this!

Absolutely love the Bioshock games, this one especially due to its parallel reality theme but also the first two for sheer brilliance when it comes to their storylines and scare moments. I cant wait to see what that post credits scene means - thats hoping that the next game (please let there be a next game!) explains it.

I just wanted to go to Paris with my waifu from the start. Live a quiet new life away from it all. :(

You know what pals ? No need to brainstorm. I got my own theory : everything (includind the full game itself) and before 14 : 35 is a dream. At the very end Booker awake from this dream and return to his normal life. Owever he's still basking in the afterglow of this painful, complicated nightmare and wish to check if her girl is still with him to know if he's still dreaming or not. Hopefully Anna should be with him (we're not sure). Deliberatly from 14 : 35 to the end, the devs don't show Booker's right hand. Why ? Because he actually lives "normally" with his child and never gone mad and tear his right hand but they don't want us to have a proof. All of this was a dream (a painful nightmare in fact).

One of the few video game endings that genuinely moved me.

I hate this game because the gameplay was terrible, a huge downgrade from the original Bioshock. I don't feel like writing an essay here so I'll just name a couple of terrible things; boring combat with rubbish superpowers, all the minigames that gave the game depth were gone in favor of linear levels, an awful upgrade system that makes no sense with a strict two weapon limit that you're always dropping for new weapons.

I've watched and played this ending for over 50 times now but I still have Chills each time I even see rapture.

Insane chills at the last piano note!!!

Never thought of it that way, thanks.

Most thought provoking, awe inspiring ending to a game. Ever.

Look at the date on his desk in the last scene. It's twenty years earlier.

Out of every video game series I play bioshock seems to have the saddest

Supposedly that was the only universe in which he accepted the baptism. Whether or not Booker now remembers everything that has happened (his dialogue at the very end seems to suggest he does), his death there has caused Comstock to cease to exist entirely.

Such an experience. Beat it today for the first time 😌😭now playing the dlc

That damn action command. Absolutely destroys the immersion at such pivotal moments in this game

This was a game which doesn't need a sequal... The ending was perfect, unexpected and mind-blowing

I think it's more related to the fact that a portal is what directly cut the finger splitting the girl across universes, rather than just leaving stuff behind.

when he is trying to get Anna back, I get chills every single time

Obviously my boy Jack....makes me so proud!

because of different universes and time periods its possible for Booker to be related to Ryan.

His eyes went green. He was at peace.

If you look closely at the tunnel behind when songbird dies, you can see a little sister crying over her dead big daddy

Also I speculated that in the credits booker lives on and raises his daughter without giving her away, without the interferance of anything comstock has ever done, colombia, elizabeth, or even the lutece's inventions, he now lives in another "door".

that lost feeling you get after you finish this game...

you are correct, the Elizabeth we went through the game with is the one who we encounter as an old woman who sends us back to save her 'again' however this is a different Elizabeth since as you said the brooch is missing, meaning booker didn't give her a brooch meaning a different universe, a different Elizabeth
