Tang Xiao: "This world is so dangerous. Mom, I want to go home."
Wait a minute, the mothership database actually has "Original Sin of the Solar Empire", "Halo", "EVE", "StarCraft", "Stellaris"? ?
And there are still Jim Raynor, Master Chief, and Archbishop Artanis sleeping in the freezer?
Tang Xiao: "Humph! They will all bow down at my feet!!"
The Fourth Calamity... ah no, long live the Fourth Empire!
