Anniversary Achievments

I am looking for people with the anniversary map packs downloaded (12 people total) to join a fire team with me and we will help each other get the anniversary achievements in infection. You must have the free maps downloaded and we can do it tomorrow at 2:00 pm eastern time if we get enough people.

I am trying to get all the achievements in the game and there are some almost impossible ones like these that you need need a boost for.

I would reeeeaaaallllllyyy appreciate it.
