It needs some improvements. There are many parts of guns that dont fit with the gun. Also, beacause the camera mode is gone, no one likes it now ( I still do :) ). You should also put some popular guns that are known by many people , such as some WW2 weapons and other wespons. And there are so much guns that the sounds dont even fit the gun it is. For example, thers only one type of silenced gunshot. There are many silenced gunshots that sounds different. ( the users will love it ) And one day, can you add helicopters? Thatd be awesome! But at the end, its a good game! ;)
