i didn't like the demo.
Lack of atmosphere l4d had.
and found it too easy. And the new infected i don't like.
Also the old infected are changed and :(
I do like the idea of the new infected and all... but now there's just too many and barely any chance for "OFUK" situations.
The spitter cannot trap someone, just hurt them. The jockey is absolutely useless in campaign as they don't try to make you run into fires or anything, just away from team mates.
I also found that the witches walking around was a bad idea. I liked it when they just sat there.
The delay on melee with gun weapons is annoying aswell. Why did they add that?
What's realism?
Basically no glow around things, no names, or any non-realistic graphics intended to help the player. Friendly fire also does full damage I think...
