Q: How does base building work and what sort of defenses will players have access to?
A: Bases are a new feature available to supergroups. They will be able to build and customize their own secret bases with the same kind of flexibility the costume creator gives their characters. Supergroups will be able choose the look of their base interiors, change lighting, raise and lower ceilings and floors, and place a wide array of objects, including defenses. There are turrets of various types, traps, force fields, and a wide variety of functional objects to make life easier for SG members.
