After reading the reviews and playing the demo I have just a few comments:
No one mentioned the AI of the enemy, which after playing the demo, I find very impressive. For example, if you shoot near explosives, the enemy will run away from the explosive. Your enemies also seem to work as a squads
The Graphics are better than the reviews will have you thinking
The 3rd Person works well, even though different from the previous 2, which I was also a huge fan of at the time. Also, you are able to comfortably move around & fire at the same time.
