I made a home video for a mutual over on Tumblr about how to get into the Dev Room in Villedor.
Your climb begins on the first floor of the basement in the VNC Tower and with a lengthy wait for an elevator.
Please don’t forget to a) do little whoops and screeches as you dangle from the grappling hook and b) open the fridge and c) sit down everywhere and d) generally turn the place upside down. Plus, listen to Horizon.
