Assassin's Creed Shadows' Animus hub is threadbare at launch, but that's fine
Assassin's Creed Shadows' Animus hub offers slim things to do at launch, but with so much in the main game, that's fine.
This is a nice touch, and selecting Shadows will then take that character straight into the Animus loading corridor (that bit where you can run around while the game gets ready) and off into Japan. You make progress with these by undertaking quick procedurally-generated missions within Shadows, of the exact same kind that existed in previous games - go here, kill this person, etc. The Animus Hub is home to a central exchange where you can swap your Keys for daily and weekly rotating cosmetic items from the game's premium store (I managed to check it on the day it had Shadows' flashy-looking Kitsune pet, which seemed a worthy use of resources).
