In the online version of Club Penguin, there were no missions for EPF agents besides Field-Ops and System Defender until Battle of Doom. Starting April 5, 2013, In-Game Missions became available. From December 1, 2010, an EPF Agent receives a paycheck of 350 coins. EPF Agents have all the necessary state-of-the-art equipment to fight crime. It is also possible to become an EPF member without the postcard or the 2009-2010 year book. Go into the phoning facility (if you are not an agent), and wait for the snow ball target to appear on the upper right part of the screen. A lever will open a tile on the wall and reveal a snowball target. Throw a snowball at it and you can become an agent!
As EPF Agents complete missions on the Club Penguin: Elite Penguin Force video game, they get promoted to different badges on the game. Here's a list of the badges in ascending order of rank:
