yes, but its still the Ark. Its the name of the city, you expand outward its still apart of the city, i mean its a Huge floating mass at sea and its all connected (physically speaking). Yeah theres 2 unique sides, but its all the Ark, and thats what the confrontation is about, control of the Ark and its resources.
The question in the OP is about art-styles more than anything. Do you like maps that have the sleek and smooth security look like the airport; or the worn, busy, and colorful maps like container city?
Although, I have a feeling the question may be a mute point, as the devs have stated that the maps are all pretty unique looking, with each map clearly being its own entity. So, the maps most likely arent going to be "one or the other"
