Bioshock Infinite Rails Dev Demo
12 March 2011
At the very same panel as yesterday's little... incident, the Bioshock Infinite devs unveiled some untextured development reels of the proposed transportation through the city. We'll have a full run-down of the game coming up shortly, but for now, enjoy this video that elaborates on the sky-based cargo rails that the player uses to get around.
We'll also have slides and screenshots for you, so stay tuned!

I hope they have a ton of rails, that looks like it could be pretty fun
