on the map crisis where you spawn next to the big house to your left,that building if your upstairs next to the balcony,if you try to shoot through the wooden railings your bullets hit nothing,i was playing search and there was a guy upstairs,so i was shooting him through the slots in the balcony and the bullets seemed to be hitting nothing as if they were hitting a brick wall even tho its was the gaps.They are like the leaves on mw2
And the flack jacket thing is a total joke,on hcsd i was behind a guy,i hit him with RPG from about 3 foot away,in his back and didnt even kill him,he turned and shot me.
