Gotham Knights Collectibles Guide Gotham Knights
You can access the entire Gotham City map and all 11 of its boroughs very close to the start of the game and for the remainder of your time with Gotham Knights. Except for the Strigidae Pages (which are available after Mission 2), none of the collectibles are locked behind missions or level caps, though you may want to unlock fast travel before heading up to the northern districts....
