Infusions are passive upgrades manufactured by the Lutece twins, under the Lutece Labs in Columbia. The Infusions are found in BioShock Infinite and come in the form of bottles in a state of quantum superposition, alternating between three states (red, yellow and blue). When Booker DeWitt comes across an Infusion, he must choose between upgrading the capacity for extra Health, Shields, or Salts. Once the choice has been made, the upgrade is permanent and irreversible. Collecting every Infusion in a single game earns the "Infused with Greatness" Achievement/Trophy.

Upgrade Choices[edit | edit source]
Augmenting an attribute with an Infusion increases it by 15% of its base amount, and each attribute can be upgraded up to ten times. There are a total of 24 Infusions scattered throughout Columbia and an additional 5 if the player purchased the BioShock Infinite Season Pass. As each attribute can be augmented up to ten times, it is impossible to fully upgrade everything over the course of the game. Furthermore, the attributes the player decides to focus on will affect their gameplay to varying degrees, especially on higher level difficulties. The following is a brief guide to choosing which attributes to increase based on the player's preferences:
Health Infusion[edit | edit source]
It is generally not a good idea to increase your maximum Health first. Though upgrading Health allows the player to take more damage than by upgrading Shields, unlike the latter, Health does not regenerate on its own (upgrading Health will, however, restore Booker's health bar to full). If the player tends to focus on aggressive combat, it is generally advised to upgrade Health after Shields, or even not focus on it at all until the endgame if the player frequently uses Vigors.
Salts Infusion[edit | edit source]
On the tougher difficulty settings, particularly 1999 Mode, upgrading Salts offers the player the greatest benefits, as Vigors are a critical component both in and out of combat. Maxing out Salts first will allow the player to cast two and a half times as many Vigors as they would with the baseline amount, and will also increase the usefulness of each Salt refill (Salt bottles refill a percentage of the player's total Salts). Moreover, upgrading Salts has the added bonus of completely refilling Booker's Salts bar. In combat, a large Salts bar allows Booker to cast more Vigors without having to rely on Elizabeth for a refill, and while exploring it lets the player cast Possession and Shock Jockey on more machines, eventually giving the player an advantage they would not otherwise possess.
Shield Infusion[edit | edit source]
If the player is less reliant on Vigors or tends to take a lot of hits, upgrading Shields first will allow the player to last longer in combat. A larger Shields bar will provide an advantage when fighting aggressively, especially when using close-range weapons. If the player chooses to max out Salts first, it is advised to follow up with Shields, as it will reduce or even eliminate the need to fill up on Health after intense fights. It should also be noted that because the base Shields amount is two and a half times smaller than that for Health, augmenting Shields will confer a smaller increase than when upgrading Health. Upgrading Shields is especially advantageous in drawn-out fights and against enemies resistant to Vigors, such as the Handyman or the Siren. In 1999 Mode, where resources are scarce, Shields have the advantage of being the player's only self-replenishing resource, and can help the player last longer in a firefight before having to retreat to cover.

Behind the Scenes[edit | edit source]
- Infusions use the same selection mechanic as the removed Pot Luck Nostrum, which would have granted the player a choice between three permanent Gear-like upgrades.
- At one point in development Booker's Shield was green rather than the yellow it finally became.
