Vigor



Vigors are the primary abilities that players will attain in BioShock Infinite. Similar to Plasmids, they grant the user access to extraordinary abilities. Unlike plasmids, which are powered by a single resource, Vigors have a limited set of charges before they are used up. Weaker Vigors (such as two electric- and psychokinetic-based abilities) will have more uses, while the more powerful ones (such as Murder of Crows) will have less. Elizabeth will also be able to augment Vigors using her abilities, making them more powerful. However, doing so drains her physical strength.

Gameplay Trailer's Vigors
Below are the Vigors seen used during the BioShock Infinite gameplay trailer:

Electric Vigor
Allows DeWitt to temporarily stun enemies, preventing them from moving or attacking. Can be used in conjunction with Elizabeth's weather-changing ability to create a lightning storm, killing any enemies under it.

Telekinetic Vigor
Allows Booker to pull objects through the air towards him, disarm and shoot enemies using their own weapons, and throw objects in his grasp with deadly force.

Murder of Crows
The only named Vigor as of yet. This Vigor sends a large group (or "murder." hence its name) of crows to attack enemies, distracting them. Used only once during the demo, it is found on Charles' corpse.

Trivia
