Bioshock Infinite screenshots: combat, environments, historical anachronism?

A new selection of Bioshock Infinite screenshots have been released. You'll see some new environments, a glimpse of combat and the anticipatory thrill of a punching about to occur. Also, Elizabeth's got hold of a book. I don't know why I'm describing this stuff to you, because they're all embedded below.

To read too much into that last one: The Principles of Quantum Mechanics is almost certainly a loaded title hinting at some element of the game. Fun fact: Paul Dirac's book of the same title was first published in 1930, eighteen years after the game is set. A mistake? A clue? A different author? A possibly meaningless and unrelated thing that I've jumped on in an effort to say something about four screenshots? I'll let you decide.

Phil has been writing for PC Gamer for nearly a decade, starting out as a freelance writer covering everything from free games to MMOs. He eventually joined full-time as a news writer, before moving to the magazine to review immersive sims, RPGs and Hitman games. Now he leads PC Gamer's UK team, but still sometimes finds the time to write about his ongoing obsessions with Destiny 2, GTA Online and Apex Legends. When he's not levelling up battle passes, he's checking out the latest tactics game or dipping back into Guild Wars 2. He's largely responsible for the whole Tub Geralt thing, but still isn't sorry.
