Anticipate running through this objective more than a dozen times before you get each and every event down correctly.

This is one of three nearly impossible objectives in 1999 mode. Head for the Sea of Doors.ĭuring the final portion of your many objectives on the command deck, you must defend the ship from several waves of enemies, including three zeppelins which can only be taken down through use of the Songbird. Once the battle is over (by having Booker send Songbird to destroy all the pursuing enemy Zeppelins), join Elizabeth at the bow of the ship to effectively end the game. Note that without Songbird to destroy the Zeppelins, the attacks will not cease, and by attrition, you will probably wind up losing (and replaying this entire frustrating-as-hell section). The Vox Soldiers with the RPGs will usually land on the upper catwalks on both sides of the ship you can waste time running up there, or more practically, have Undertow and shove them off to their death(s).
