Quick Tip Guide on how to become un-zombiefied in Infected.
Step 1. After being Infected leave the game.
Step 2. Change your clan-tag to anything you want (if you already have one just delete a character and edit it next game)
Step 3. Search your recent players and join the session of the game you were just in.
Now you are un-infected!
