A sequel to the now trilogy, this game differs from the first two games by not being set in Rapture, but on a floating island called Columbia. More splicer mayhem with the ever prevalent hacking and plasmids!

The twist is that this setting is not only not underwater, but it is a floating steampunk style city in the sky!

Here's the official description from Irrational Games:

BioShock Infinite puts players in the role of Booker DeWitt, a hard-bitten former Pinkerton agent, together with the revolutionary AI companion, Elizabeth. The two struggle to escape the sky-city of Columbia, in a 1912 America that might have been.

Armed with an arsenal of new weapons and abilities, they face menacing enemies, in unique expansive environments. Classic BioShock gameplay joins innovations such as aerial combat on high-speed Sky-Lines in the service of an immersive storyline – an Irrational Games signature.
