"Rise and Fall" is the name of the Terran campaign being created as part of the "Midway" Project.
Rise and Fall will cover events in the years between the end of the "Awakening" Campaign and up until StarCraft II starting point.
It has not been decided yet on StarCraft Universe whether StarCraft Midway: Rise and Fall will be created with use of the Galaxy Editor or the original StarCraft's Map Editor.
Rise and Fall is still under development.
More information will be released in the coming weeks.
