Chests are special, hidden boxes that require special keys in order for Booker DeWitt or Elizabeth to unlock them. The keys can be found throughout the game’s world by looking and browsing various rooms and territories. These chests contain infusions and other in-game bonuses + boosts that Booker can use to his advantage and to become a more powerful hero. It is sad that only two of these chests exist in the entire game. But none the less it’s worth to locate the keys and to open them. To find the chests: one is in the bedroom of Lansdowne Residence and the other is located on the second floor of the Bull House Impound. Hope you’ve enjoyed this guide and short brief of Chests and their keys. Read more about BioShock’s Infinite features right here in gamespedition.
