BioShock Infinite Infusions: should you upgrade health, shield or Salts?
Choose permanent upgrades deliberately and understand the base campaign’s Infusion count and lockpick detours.
The original 2013 BioShock Infinite Columbia campaign on PC. Burial at Sea and Clash in the Clouds are outside scope; the Infusion guide explicitly separates the Season Pass bonus. Images are 2K publisher assets from the Steam listing.
Choose the stat that solves your recurring problem

An Infusion permanently increases one of three capacities: health, shield or Salts. Shield is a useful early choice for players who regularly retreat to recover; Salts supports frequent Vigor use; health provides more room when damage gets through. There is no single mandatory order. Review why you lost the last encounter before making another irreversible choice.
Separate the initial shield from optional upgrades
The first shield acquisition establishes the shield system. The base Columbia campaign then contains 24 collectible Infusion upgrades, with five additional Infusions supplied by the Season Pass bonus. A guide count that includes bonus items can therefore differ from a base-game checklist. Decide which edition’s checklist you are following before assuming a missing bottle is a bug.
Save lockpicks for doors with useful exploration rewards
Elizabeth opens optional locks using the picks you find. Read the displayed requirement and look through the surrounding area for supplies before committing your current stock. Some Infusions sit behind locked doors, while others require an extra key or puzzle. Keep a note of a nearby locked room so you can return before leaving the district.
Search early side paths before the campaign moves on
The Blue Ribbon Restaurant introduces the shield; later early opportunities include the Lansdowne Residence chest and locked areas around Soldier’s Field. Keys and ciphers can point back to a place already visited. Resolve a local clue while the route remains accessible instead of assuming every earlier area can be revisited freely from the late campaign.
