1999 Mode is an unlockable mode of gameplay that is more difficult than the 'Hard' setting. It can be unlocked by either beating BioShock Infinite for the first time or else by entering the Konami Code (up, up, down, down, left, right, left, right, b [cancel], a [confirm]) while in the game menu. The developers of BioShock warn players that the game will not "feel like BioShock" in this mode.

Changes in DevelopmentEdit
1999 Mode was originally meant to emulate the feel of older or experienced shooters. Players would have to choose a "class" for Booker, such as Heavy or Long-Ranged, each with its strengths and weaknesses. Players would also have to make permanent choices that would have irreversible consequences--for example, Gears, called Nostrums at the time, would not have been removable or replaceable. This was changed when the Gear limit was shrunk down to four and they became randomized on each playthrough. In the finalized version of the game, 1999 Mode is simply an extra-hard mode with no drastic changes to the core gameplay.
