I've not played it, but I a friend of mine has been bugging me to get it. Meta score of 90, 40 bucks on steam, all the amazon reviews on great. Id say its a steal.
I paid close to full price and it was not disappointing. I also got it for the Onlive service for 5 bucks a while back so I actually bought it twice. The game stays true to the Deus EX of old and can be classified as rpg/shooter.
