You will also need to communicate far more than any other difficulty due to how difficult this run may be. This will help with Expert and more advanced playthroughs.īefore you start playing on Expert you should have found yourself a solid team, as well as running through the levels several times to learn the best places to defend. I suggest you play through each campaign at least once so you know where everything is. Some achievements will require multiple playthroughs and you will also need to complete miscellaneous tasks for various other achievements. Much like the previous game you need to make your way through the various campaigns, you will earn most of your achievements playing through the different levels. If you don't want to play with random people use the Achievement Trading Thread to find other players. While running through the campaigns with your team, use mics and communicate on a regular basis. Remember you will be playing as a team, so if you feel the need to run off on your own do not expect to survive on your own. You will be battling your way through hordes of Infected and a new set of Special Infected to reach your goal.

Much like the first game your goal is to escape the infested confines of Louisiana. You will be introduced to Ellis, Nick, Rochelle and Coach.
