You are alone. Hordes of the infected roam free, hunting for the last remaining vestiges of the healthy. You have stumbled across an old text that suggests a way to defeat the hordes, giving you a small ray of hope in an otherwise bleak existance

Find and activate the gates, but be careful. Activating the runes incorrectly will diminish the effectiveness of the gates, and you may not be able to bring down the entire horde. Good luck!
