Key To Pirth

From Halopedia, the Halo wiki

Key To Pirth

Key To Pirth is an Achievement in Halo Wars that is worth 50 Gamerscore. It is obtained for beating Act 2 on any difficulty. Act 2 consists of the missions Arcadia City, Arcadia Outskirts, Dome of Light and Scarab.


  • The name is a reference to Pirth, the capital city of Arcadia, as all the levels in Act 2 take place on the planet.
  • The name is also likely a reference to the custom of giving a key to the city to someone, usually a hero. In this case, its likely supposed to be a reference to the UNSC Spirit of Fire crew and the player saving Pirth and Arcadia from the Covenant invasion.
