Played condemned for the first in a while and have decided that the attempt at adding atmosphere is in fact annoying.
They decided to reduce visibility to only that within your torches beam, very atmospheric, well at first but even in the darkest and depressing of places they have been know to use lighting.
I think what I am trying to say is that yes this does add atmosphere but a little variaty in how this is acheived would have been more enjoyable.
