God the comments on that demo are so idiotic. People saying how the doors don\'t splinter, etc... Do they not understand this is just a concept demo? Friggen tards. So glad I\'m of the pong generation and can appreciate this crap.
Interesting concept though. There gets to be a point though blowing up interior walls and such that the believability isn\'t there. All buildings have a few load baring walls that if you took them out the whole building would crash down. I guess all of that would be taken into account in a real game.
