The Action Arcade is a retro-style arcade that's accessible through a variety of locations in Paragon City and the Rogue Isles. Owned by Lydia Pacius, a member of a family of interdimensional business magnates, the arcade itself exists at a dimensional nexus, and as such, is able to provide access to several places in space and time through its game booths.
Currently, only a small portion of the arcade is open, but a much larger portion of it will become accessible once renovations are complete.
