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 on consoles 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 shooter games. 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.


BioShock InfiniteEdit

  • Conserve your money.
    • Spend your money carefully, this difficulty makes you lose 100 Silver Eagles if you die.
    • Safes often contains a larger amount of money so try to gather Lockpicks to unlock them when found.
    • Use Possession on Vending Machines, it will drop around 10 Silver Eagles.
  • Avoid conflict.
    • Make sure you don't open fire on civilians, stealing valuables and trespassing restricted areas may trigger them.
  • Try to find as many Gears and Infusions as possible.
  • Concur the checkpoints.
  • Search through everything. With limited resources, it is important to try to scavenge anything you can. Go through anything from trashcans to corpses.
    • Some items may add health but reduce salts (and vice versa), like cigarettes and alcohol.
  • Finding a good cover is a crucial part when in combat with many enemies, until you're ready to fight or just as a hiding place.
  • Try to hit enemy weak spots: Head shots for the normal human and the Siren and aim for the heart when against a Handyman.
  • It is highly recommended to buy the Possession upgrade: Possession Aid ( $50 ) as it gives you the ability to cause some enemies to commit suicide.

Burial at Sea - Episode 1Edit

  • Market and High Street has no combat, so the player can safely take their time to gather up on supplies, mainly money, before heading towards the combat-filled department store.
  • Drinking alcohol will drain the player's EVE, so it's recommended to stay away from the flask, as Plasmids are very useful (and without upgrades will also drain your EVE) and finding EVE is not that common.
    • Being trigger happy while searching through containers can cause the player to lose all their EVE, as they may contain several alcohol beverages (this will also make the player drunk).

Burial at Sea - Episode 2Edit

  • Try not to draw attention to yourself and take advantage of the stealth gameplay, as Elizabeth is very vulnerable and doesn't have a Shield.
  • After firing a Tranquilizer Bolt on an enemy, search its body for a chance to get the bolt back.
    • If you miss, the bolt will usually be intact where you shot it, but not for too long.


Behind the ScenesEdit

  • The mode is an obvious reference to System Shock 2, Irrational Games' first title, which was released in 1999.[1]
  • Auld Lang Syne, the achievement unlocked for finishing 1999 Mode, literally means "Old Times' Sake", referring to the mode's throwback to classic shooters.
