Guide updated with details on the DLC. Only one that I am unsure of right now is the Gold Medal one. If anyone can let me know for sure on this, I will appreciate it.
Also I noticed that when players leave the game, sometimes one of the Pros will take over. I don't know if you can knock them out to get the Took Down a Pro achievement or not. If anyone has done it and know let me know and I will add it to the achievement guide and give you credit as well.
