You wake up to sirens, explosions, and chaos. In a panic, you grab your phone to see what's going on. You've got about a thousand urgent messages, most asking if you were alright. Many saying emergency in your area, EAS alerts, but some are more important. The military telling you to evacuate immediately. Still not sure what's going on, you look outside.

People are eating each other alive, people shoot other people without hesitation.

What has happened? What will you do?
