Because wibbly-wobbly timey-wimey stuff.
I see what you did there.
I got Bioshock infinite for free when i bought my gpu lol. it’s rly an amazing game, i love the gameplay and everything. The ending just like…What? i rly didn’t understand why they ended with you drowning from 3 of the same girl(but from diff. dimensions apparently) and poof end.
the rest was really awesome, i would recommend this game to anyone looking for some fps games.
The ending is suppose to show where the original choice was made. And you drowning was suppose to stop that choice from every coming to surface. However they may have already let you make that choice in the first place and just drowned the man who he would of become rather then the man he already is. If you wait until the end of the credits you will get one more scene in the game.
