Since 2019, Ubisoft Games has no longer been logged on to Steam, and the PC version of the game is only available on its own Ubisoft International Mall and Epic Games Mall. And now, Ubisoft Games seems to be back on Steam.
It is also learned that games including "Assassin's Creed: Valhalla", "Age 1800", "Champion Sprint" are returning to Steam. The "Assassin's Creed: Valhalla" store page is now online and will be officially released on December 7. The price has not been announced yet. For reference, the price of this work in Ubisoft Mall is 298 yuan for the standard version, 398 yuan for the luxury version, 498 yuan for the Ragnarok version, and 698 yuan for the full version.
It is not clear why Ubisoft stopped putting its PC game on Steam, nor why it is back now. Ubisoft also removed other games from Steam at the time, including Era 2070, Assassin's Creed Liberation HD, Silent Hunter 5: The Atlantic War and Space Legion, but these games seem to be re-listed from Steam except Space Legion.
