Bioshock Infinite - Siren boss fights (1999 mode)

[WARNING: THIS VIDEO CONTAINS SPOILERS FROM THE MAIN STORY OF BIOSHOCK INFINITE] This video features all the three boss fights against the Siren (really Lady Comstock) from Bioshock Infinite. Notice that the video was recorded while playing on 1999 mode. To be more precise: - The first fight is triggered by trying to open Lady Comstock's sarcophagus in the Memorial Garden. Upon defeating the Siren, she will just leave - The second fight (4:40) occurs after you examined the tear in the Bank of the Prophet's caveau. The massive safe door will be opened and you have to fight the boss in the main area of the level. Again, the boss will leave upon being defeated - The third and final fight (6:35) takes place in Victory Square near the entrance to Comstock's House. After defeating the Siren for the last time a cutscene will take place and you'll be able to advance While she's mainly considered a cool fight with an interesting gimmick on easy or normal mode, the Siren becomes a NIGHTMARE to fight on hard and one of the few fight that really give 1999 mode a run for its money. On top of the boss close range AoE attack being extremely powerful, the Siren's main ability, go around the area and rise the enemies you just defeated again, and again, and AGAIN will make you deplete all of your resources if you don' t approach the battle in the "smart" ways. Also the three areas you fight the boss in doesn't feature any Sky-rails whatsoever, so your main mean to damage and escape enemies during gunfights is effectively shut down. The main trick to face the Siren successfully is to either set ablaze or electrocute the minion the boss brings back to life: since in normal gameplay using fire or electricity on humans enemies make them disintegrate instead of just dropping dead, the Siren will soon run out of corpses to ressurect. Note that simply decapitating the soldiers won't do and they can be still resurrected. The most straightforward way to take on the Siren (which I used as well) is therefore to use either an upgraded Devil's Kill or Shock Jockey vigor to lay down traps to catch up crowds of enemies (the Storm gear helps with this), disintegrate them and use your weapons of choice against the boss. The Devil's Kiss is arguably the best option here because it's one of the few vigor that can affect the Siren and do some decent damage to her. Another popular strategy is to use the upgraded version of the Charge vigor and gears that give you stronger melee attacks and chances to set nearby enemies on fire to close in on the Siren as she tries to resurrect people and hit her with your Sky-Hook. She will do some damage to her and set on fire the minions she just raised in the process
