This is a spoiler blog post about Zombies, Run!
Dude!!!!! This is so much cooler than I expected it to be!!! So when you're running you "pick up" items like water bottles, USB keys, sports bras, etc. If you run too slow and a zombie catches up to you, you drop some of the supplies to distract them. Sometimes, you pick up really specialized things. "Artifacts" like an article from a newspaper. Or... A note from Netrophil.
The paper I picked up had an email address on it. I googled the address, found out it was part of the game, and then emailed them.
