If you're lucky enough to live in LA, that is. Scott C, designer of all things Brutal Legend and Psychonauts, will appear at Secret Headquarters, and he's giving you the address. This all happens on Saturday, May 3rd, from 8 to 11 PM (USC time, obviously - obviously). Go over there and express your love to Scott C. by dressing-up as the Milkman.
