My thoughts after watching the beta videos:
* Players are much too fast, especially when climbing stairs.
* I saw hardly any teamwork or direction, except for a few times when people were in the same room/building, but that didn't seem to work very well for them.
* The sound of the bullet smacking into flesh was really good
but it seems to play at the same volume regardless of distance which is bit lame in my opinion.
* There is too much clutter on the screen, especially the icons for climbing over fences, not as bad as CoD but still not good by any stretch.
* The fights seemed very isolated and 1-on-1 in a number of places (could just be the player), I didn't see anyone following a squad-leader for more than a few seconds.
* The notifications about who is attacking what is ridiculously overpowering, I could live with it being a quarter of the size and tucked away in a corner somewhere to be honest.
* The voices were very corny.
* I don't like the idea of flashing up messages about stat tracking (Kill in objective +2 teamwork etc - and for that matter how does killing someone give you teamwork points just because they're in an objective?)
* I'm hoping "killed from location" is in relaxed realism?
* Healing takes less time than a reload? Again is this relaxed realism?
* I loved the animations.
* Environments looked great - especially the colours.
* Graphics were quite impressive in most places, though a few areas looked a bit barren.
* Sounds of weapons and ambient noises were really well done.
* The part where he cleared out the top level of that building was awesome
Edit:
* The fire animation is incredible!
* Tanks appear to always explode catastrophically, which in my understanding was not the norm.
