In BioShock Infinite, Tears—or rifts—play a crucial role in gameplay and narrative development. Players interact with these Tears by pressing a designated button, typically “F” on PC, while near a shimmering rift in the air. Elizabeth, an essential companion, assists in this process, opening the Tears and allowing players to explore alternate dimensions or past moments.

The Tears serve multiple functions that enhance both the gameplay experience and the story. Here’s a breakdown of their key roles:

1. Access to Alternate Realities and Moments: By revealing glimpses of different dimensions or time periods, the Tears provide players insight into objects, characters, or events that are not present in the main timeline. This mechanic often requires players to enter these rifts to progress through the game, solve puzzles, or gather important narrative clues.

2. Resource Generation: Opening a tear can yield useful items such as ammunition, salts (which are necessary for utilizing Vigors), and even weapons. This feature not only aids players in their journey but also incentivizes exploration and interaction with the environment.

3. Combat Enhancement: During battles, Elizabeth’s ability to open Tears becomes particularly valuable. She can pull objects, explosives, or even turrets from alternate dimensions into the current fight. This dynamic can significantly alter the course of combat, providing strategic advantages, cover, or environmental traps to defeat enemies.

4. Narrative Progression and Secrets: Certain Tears are integral to advancing the story and uncovering hidden secrets. They often reveal pivotal plot points or insights into crucial characters, such as those connected to Chen Lin’s situation or Lady Comstock’s ghostly presence. These revelations contribute to the rich backstory and complex narrative structure of BioShock Infinite.

In essence, interactions with Tears—facilitated through Elizabeth’s powers—not only enhance gameplay by offering alternate realities, useful items, and combat advantages but also deepen the storyline by unpacking essential plot elements and mysteries within the game. This multifaceted approach illustrates how mechanics, narrative, and character development intertwine in BioShock Infinite.
