Bioshock Infinity: The Drownings

[Part of the Wasted Land story]

Despite the gunsmith being deceased from a police interrogation, Booker and Liz manage to find the hidden weapon stash for the Vox - with Booker gaining a nice sniper rifle and RPG out of it which he uses to take down the pursuing Handyman. With the weapons quickly distributed the Vox start a very violent revolution across the city and predictably, they are just as traitorous, violent and evil as their oppressors - reneging on their airship deal to start hunting them too as Liz is the prophet's "chosen one". After exploding a lot of them, they take the airship anyway but are then stopped by the monstrous metal bird who crashes their ride into a building - and somehow they survive again? [Note: there's a stupid part where you already get an airship but decide to sabotage it because the protagonists are idiots]

Figuring that the only way to get past the bird is to control it, the pair head to the prophet's house but find the door locked by a scanner which will only accept the hand of the prophet's dead wife. She isn't as dead as they would like though, and must spend a decent chunk of time chasing the evil spirit around the market place as she raises the plentiful supply of dead bodies in her wake. They eventually get the gate open but Liz is captured by the metal bird as they are crossing the bridge to the estate. Fortunately, it only takes her somewhere inside so Booker goes in guns blazing against the prophet's elite until he can rescue the girl again and kill the prophet himself via drowning.

Curious that the bad guy didn't just do this prior to the rescue attempt.

Hijacking the prophet's airship, Elizabeth works out how to control the metal bird using the power of music and gets it to destroy the numerous Vox dirigibles that give chase. Ultimately, she also uses it to destroy the remainder of the statue she was housed in after the prophet revealed it to be a siphon of some sort. Sure enough, with it gone her full powers manifest and the steel bird becomes hostile once again. It is too late however as with a snap of her fingers she transports herself and Booker into some deep underwater city with the great beast outside in the water. There is nothing it can do but die. She then turns to Booker and tells him a truth he doesn't want to hear before drowning his mind in darkness.
