UFO Incursions (Apocalypse)
This page lists the types of UFO incursions, the craft involved on each alien mission and their specific roles.
Each incursion will consist of 1-7 craft, each with a specific role than can be consulted on the tables below. Each force will have a primary mission which can be Infiltration, Subversion, Attack and Overspawn Drop, usually with crafts flying as escorts. In a few cases an Infiltration or Overspawn Drop force will be joined with craft assigned to Attack hostile buildings.
