In case you missed it video footage has popped up online from a demo of Deus Ex 3. 26 minutes worth of it.    This is all gameplay and it looks great! 
 
NOTE: The demo may be the same one shown to press already, so it is likely not reflective of the current state of the game.
 
ALSO: The footage looks like it is from a cam view (though it is pretty clear), so there are a few instances where the bloom seems particularly extreme.
 

SPOILERS IN THE VIDEO: They do show the outcome of one of the missions, exposing one person's identity.  If you really want to avoid spoilers: Stop watching at the 6 minute mark and skip ahead to the 14 minute mark. 
      

Definitely looking forward to this game.

I really want to watch it, but I also don't want spoilers. Argh. Does it seem like a spoiler vital to the overall story? 

This looks awesome. I also love the fact that since Aliens, all futuristic spaceships look a hell of a lot alike. 
 
I do think this game needs a little vertical syncing, though.

Deus Effect?

Watching the video now, and I have to say, after the first line that guy in question said, I figured out who he really was.  
 
Also, I must say two more things: 1. This game looks pretty great. B. I'm not so sure about that ability to smash that wall down, because even though the wall was cracked, I don't think there will be too many actual things that can be smashed like that in the game, and when you can smash a cracked brick wall, but not a thin door, it kind of breaks the immersion.  
 
Also, I always like it when games let you play it without killing dudes. It gives me something to try to do (and then fail miserably at). 

I kinda wish they would have gone into  the cloaking more. There didn't seem to be any HUD indicating it was running out or anything.

I love the visuals in this game. They're not really technically incredible as far as I can tell, but the city looked so busy and alive, and it's definitely got a cool art style. Takedowns are getting a little overdone nowadays it feels, but it seems like they're only effective if you have the drop on guys, because otherwise you'll get gunned down if you try to play the game like it's Turok. Lip-syncing could use a bit of work.
 
Overall though, really impressed.

I can not wait to play this game, but if it disappoints me I will probably rage all over GiantBomb about it.
