There are unlockable maps, villain groups, and costume parts. You unlock them with tickets from the ticket vendor (above the datastream used to enter AE missions).
My arcs are constantly shifting, just search for GadgetDon for the latest.
The world beware! I've started a blog
GadgetMania Under Attack: The Digg Lockout
ParagonWiki has a nice listing (with pictures) of all the maps available in Mission Architect. However, in practice, many of these maps aren't available (City02, for example). Are some of these maps unlockable? If so, how do I unlock them?
I've searched all over this site and ParagonWiki and can't find the answers anywhere.
Please try my arcs:
