Travelling to different areas will make different Outbreaks, Challenges, and Property available to you. As your Slayer defeats certain Bosses, more areas will open up for zombie eradication.
The area you are currently in is displayed in the Travel menu by your Slayer info. Open it up to see which areas you have unlocked.
