It's pretty good. It does fill in a bit of background, and the gameplay is pretty good, with a proper Deus-Ex-Style bossfight.

It's more of the same (which is good) with some addition to the main HR story, an excellent boss fight and a bit of original Deus Ex tie-ins.

I enjoyed the DLC.  You can stealth-run through it in about 80 minutes for the Factory Zero achievement, but to explore everything and run it carefully will take you 4-5 hrs.  The boss fight was SO much better than those in the game (which I just considered annoying diversions requiring my stealth pacifist character to exploit the stun gun and typhoon for) - this one can be completed non-lethally as a complete Ghost.

Has Halo made me stupid at quality FPS's?

Yes

Hope we'll see more high quality DLC coming out though, extending the life of this product would be very prudent. I'm definitely going to play it again some time from now, been 99% nonlethal and mostly Ghost, sad I didn't get the achievement though. Maybe I should run&gun it next time (Harder than it seems, I absolutely cannot do this in Deus Ex 1 until MJ12, for instance), it seems there's plenty of stuff that can be destroyed and blown up in the middle of gunfights.

JCDN: As I said earlier. run & gun isn't really too hard. It's probably the easiest way to get the achievement for finishing it on the hardest difficulty.

Extra Credits did a Human Revolution episode this week:

Extra Credits is a video series that started on The Escapist and migrated to Penny Arcade earlier this year. It is a BRILLIANT series that discusses video games in terms of design, meaning and how they can improve. It's probably the most mature commentary on video games out there. If you haven't heard of it before, I suggest you try and watch the entire series, especially if you're into game design/development.

[Mongoose]

Yes, that.  Extra Credits is awesome.

It's probably the easiest way to get the achievement for finishing it on the hardest difficulty.

With the exception of save/reload for the achievements requiring lethal moves, I got every achievement for the game, including the "Give Me Deus Ex" on my first playthrough.  If anything, striving for Pacifist/Foxiest makes a "Give Me Deus Ex" run stupidly easy, because you never get spotted out of sheer necessity.

Dekker - Fedorova = stun gun bait.  Unless you were silly enough not to bring one along, in which cause get the EMP armour upgrade and shoot the electrical conduits around the room.  5 shots on a fully-upgraded pistol to each will make them detonate and electrify the floor.  Bye bye, murderous *****.
