The latest BioShock Infinite trailer is all about showing off the bonus Industrial Revolution Pack content that comes with pre-ordered copies of the game. More precisely, you get a bunch of gameplay clips interspersed with screens detailing each piece of content.
The Industrial Revolution Pack includes three in-game gear items, a new feature for BioShock that effectively takes over the role of the first game's Gene Tonics. Players will also receive $500 worth of in-game currency, five lock picks to start with (very useful), and the Industrial Revolution puzzle game "which unlocks stories of Columbia and allows players to pledge their allegiance to the Vox Populi or Founders through Facebook."
Just hit play and watch the footage. That's what you're here for.
