Adding to the story of the Infinite game and as well a little more detail to Bioshock. Dewitt's have a very tragic life.
This time we play as Elizabeth, which finds herself right in the middle of a war on Rapture, with only bad deals around her.

Honestly, as much as I like this, I wish they had connected a bit better the storylines as with almost any prequel sequels, they added so much stuff that didn't exist on the original game and it just feels a bit odd. I try to ignore it, tho.
