Hello I have a problem does not exist in my friends and found I have a present in Black Ops 2 zombies namely if you want to fire on the zombies to detract from the blood and I come out something strange is white smoke , I hope that I find your solution because I want to enjoy the game . . . Ended

This is the video for clarification

*Notice that the first two were killed by blood to detract them but comes out white smoke

*I apologize for the poor-quality imaging because it was from my mobile phone and I put the highest quality in order to be clear 1080p
