Has better combat than any newly released fps. It's absolutely astounding how much the environment and enemies react to what you are doing: lights flickering, papers flying everywhere, cabinets getting knocked over, smoke from gunfire, explosions, enemy call-outs regarding your location, even bickering among themselves from time to time... You can do kung-fu for no explicable reason and it is hilarious.

Only issue is getting the thing to work; this is one of those games where u gotta do a bit of tinkering with the steam guides to fix crashes and get some community improvements, but once you're all set up the experience is golden.
