Okay so I just unlocked a mission on earth somehow and it's called (as it says as the subject for this) The First Firewall. I went down into rasputins bunker in the area where you verse omnigul's minions in the dark below campaign and I had to fight off a few knights before facing off with what looks like the knight mini-boss from PoE. After defeating it I received a "curious transciever and there's a pass code on it that I need to enter. Is everyone else unlocking this mission or is it just me?
