There are no public tours currently, but from experience working at Activision, and several other triple A game companies it can be arranged. Call the front desk and asked to speak with someone in their marketing department, or public relations department. If that fails comment on this thread and I will make a call for you and get the connect you will need.
Currently there are no open public tours how ever with the Esports Programs currently being held in collaboration with Riot Games and certain Universities maybe can be done, but you've to ask for the guys in those especifi programs or internships department
