Grey Goo

Grey Goo launched on January 23, 2015 as a base game with three playable factions. The first paid DLC, the Emergence Campaign, shipped on June 9, 2015, adding a story expansion and a fourth multiplayer faction teased as upcoming. On January 31, 2016, Petroglyph released "Descent of the Shroud," introducing the Shroud as a full fourth playable faction — the game's single major post-launch content release. Alongside this update, the developer released the Grey Goo Definitive Edition, which bundles all content including the Emergence Campaign, the Shroud faction, new units, Mission 16, and the complete soundtrack. Following the Shroud launch, the team shipped several balance and bug-fix patches through March 29, 2016, and maintained weekly community events into early 2016. The last developer news post on record is from March 29, 2016. Both DLC items in the store listing are fully released, no unreleased content is listed, and the Definitive Edition explicitly packages "all DLC" as a complete collection. The December 2015 producer's letter teased upcoming announcements, which were subsequently fulfilled by the Shroud/Definitive Edition reveal in January 2016. No further content has been announced since that release, and there has been no developer communication since March 29, 2016.
