Matt "Positron" Miller - Lead Designer of City of Heroes and City of Villains - discusses the planning that went into the upcoming free expansion, Issue 10: Invasion, in this latest Dev Diary on the City of Heroes website.

Our first thought for Issue 10 was to bring back the 5th Column, a villain group that disappeared when the Council was introduced in Issue 3. But in the end we decided to focus on one of the greatest threats to Paragon City and the Rogue Isles, the aliens known as the Rikti.
