I liked it for the fun single player level design mostly. The game engine also paid a lot of attention to details othe fps did not. Different reactions based on where the bullet hits an enemy. Security cameras. Alarms. Stealth sections.
I really enjoyed the music and atmosphere. It really made you feel like you were in a James Bond movie. I also enjoyed all the shout-outs to the old movies too - stuff like the Moonraker level.
