You just click the button to do another outbreak. If you want to switch countries then there's a button at the top next to your profile pic. To unlock new countries you need to kill a single boss first. Add me on facebook I'll squad and help you out however you need. http://www.facebook.com/lance.vinosa?ref=tn_tnmn
Yeah. Each outbreak listed will have a certain level requirement to open it. Once you have reached that level, it will no longer be shaded, but bright and vibrant letting you know that you can now access it. Click on it, then purchase whatever items are required to have, and enjoy slaying the next set of zombies. As Bacon said, at the top right of your profile is the TRAVEL button....once all outbreaks are complete in one country, you must then move on to the next....but alas, you must defeat whichever level boss to move on to a new country. Knowing exactly where you are in this proces is critical to accomplish your DGP's, as you only get 'outbreak' credit for killing zombies in your most recent outbreak.
