Cities Skylines Patch 1.4.0

Features

  • Added 33 new achievements
  • No longer possible to build robots on planets belonging to sectors
  • Added victory event after defeating the Prethoryn Scourge
  • Added new events for discovering additional Precursor anomalies, so that the quest chains can always be completed
  • Changed the way the Extradimensionals work: Instead of spawning reinforcements as soon as a fleet is lost, the Extradimensional portal will create new fleets at a fixed rate depending on the number of dimensional anchors the Extradimensionals have placed in the galaxy. Dimensional anchors are a type of station that the Extradimensionals construct, and their main portal is invincible while any dimensional anchors exist in the galaxy. This should make the war against the Extradimensionals more of a long-term fight and less of a surgical strike against the portal.
