Quick Achievement Guide on how to obtain the Organic Shield and Chaos Adverted achievement for anyone that didn't know how or what to do. These two achievements were obtained on the third mission but can be done anytime after the first mission since it's easyer to go agianst zombies then Spec Ops. These achievements can be obtained not on in Campaign but Multiplayer aswell at anytime. Feel free to leave any feedback if your having any problems.
