If you're not worried about spoiling the demo for yourself (which, we suppose, would lead to spoiling a very tiny portion of the game by extension), you can see some of the gameplay the demo covers in the video. Or you can wait until you get to put yourself into Sam's goggles for yourself. Oh, did we say Sam's in it? And that there would be goggles? Whoops, spoilers!
[Thanks, Daniel!]
