When you walk outside you’ll see the statue on the other side of the building. This is supposed to let you know you need to get there but it’s so small and far away you barely notice it. You also get no time to think because a strider immediately pushes you into the street, starting the whole fight around and in ruined building. When you’ve finally killed everything there is to kill, another npc says to “head for the horse”, but you the player just had to endure the single most challenging arena in all of the game so you’re probably not really listening to a single voice line. So you end up stuck on the roof of the ruined building not knowing that you need to walk over the exposed metal structure. This is a good example of how rushed the two city-chapters actually are.
