I've played the map and I have to say......AWESOME!!
Things to improve on;
Increasing the FPS would be a big +
Falling rain
Able to jump through broken windows
I liked;
Have to open/close doors
The Fire escape
The Park
The barb wire that hurts
Man hole covers open/close
btw: I noticed that in the dirt piles there were pieces of glass that seemed to show ur reflection. Is it possible to have a mirror that would show ur reflection when u stand in front of it?
