All of 18 rounds. 2 hours, 3 minutes, 17 seconds. Includes at least 20 minutes of running around in circles with a zombie, one member of our party fighting with his girlfriend for 7 minutes, and the culmination of at least 35 hours within 3 weeks of hard work. So much was dedicated to this Easter egg, we got it down to a science. Best white light of my life hahaha maybe not but you get the idea!
