I just finished the demo on easy and Normal, you can just run and gun pumping nectar on those difficulties. Some parts looked really good while some parts looked bad, two of my friends turned red the first time and it takes alot of hits to kill them. I overdosed on the drug and the screen goes all screwed up and it starts to fire for you. And everyone is all black, so you can't make anyone out.
Some parts were pretty stupid, my character would not even go up this tiny little hill and he kept getting caught up on crap on the ground, it was also impossible for me to see anyone of the bad guys without using nectar. There was also a guy hiding between thees two logs and the game would not progress until i killed him even though he was on the other side of the map and we were in the downed heli or whatever it is. It was almost impossible to see him, even when i was standing right near him.
The demo was OK though, better then pretty much every other shooter demo on the system, which is not saying much.
