BioShock Infinite is an upcoming first-person shooter video game, and the third game in the BioShock series. It is being developed by Irrational Games for a 2012 release on the Microsoft Windows, PlayStation 3 and Xbox 360 platforms.BioShock Infinite is not a direct sequel or prequel to previous BioShock games, taking place in an earlier period and different setting, though it features similar gameplay concepts and themes. The player controls a former Pinkerton agent, Booker DeWitt, as he attempts to rescue a woman, Elizabeth, trapped aboard the collapsing air-city Columbia in 1912.
BioShock Infinite is a first person shooter with role-playing game elements similar to the previous two games. As DeWitt, the player moves about the various structures of Columbia using a grappling hook, a series of railways connecting the buildings called the Skyline, and other transport means to search for Elizabeth. The player will gain weapons which can be used in numerous ways within the environment, including on the Skyline, to defeat enemies.DeWitt gains powers and abilities by using vigors and nostrums that are found through Columbia, the equivalent of BioShock’s plasmids and tonics. Vigors grant activated powers such as telekinesis, electricity manipulation, or animal control (as seen by the manipulation of a flock of crows within the gameplay demo), while nostrums are passive abilities that can improve the player’s strength or damage resistance. Unlike BioShock in which the player was able to use special Gene Banks to alter the loadout of plasmids and tonics they had, the choice to imbibe a certain vigor or nostrum is permanent and cannot be changed later in the game, placing emphasis on the consequences of the player’s choices throughout the game. Infinite does not use EVE, the equivalent of magic points, for powering abilities gained by vigors or nostrums. Each container of vigor has a limited number of charges in it, and while more can be found around the game’s environment, the player can only carry a limited number of vigors into battle, with more powerful vigors containing fewer charges. Nostrums are permanent changes to the character and cannot be removed once used. These come in two types, stable and unstable varieties, the latter referred to as “potlucks”. Stable nostrums are more expensive, but the player knows exactly what effect applying the nostrum will gain them. Unstable nostrums are cheaper or can be found lying around the environment, but upon use, require the player to select one of four random effects to alter their character, an idea inspired by Heroes of Might and Magic according to Levine.
