Don't be a flatliner. If you let the infection take hold you'll be bound to a undead life of meandering aimlessly along hoping to bump into brains. But wait! What's this? Some sort of antibodies in the shape of an orb (isn't that a symbol for royalty or something?). It feels like it's defeating the disease, humanity is coming back, if only momentarily. Perhaps if you could find the person or thing that dropped these glowing balls you could keep your heart beating. Maybe, just maybe you could be human again. ...Also, perhaps you'll find out why it is you became a zombie while wearing a top hat...then again, probably better you didn't. Probably something freaky. You know TMI. Come on. Would you LEAVE IT, ALREADY!
