Rift camps, the subway, and an Ashford five times larger

Ashford, a floating island
The town is five times larger, broken apart in the void: streets, a mall, a parking garage, an airport, a hospital, a park and a school, each quarter with supply caches to search. The outskirts are dangerous after dark. Families are coming home too: Bruno the carpenter, Mai the baker and Dr Elias.
Rift camps
From day 8, camps raise their banners in the forest. Shield knights barely feel a blow from the front, so get round behind them. Archers shoot from behind the shield line and commanders order the charge. Beat them all, then break the banner to take the camp.
Take three and the next is a war camp, guarded by the Rift Warlord. Leave a camp standing too long and its knights march on your gate.
New weapons: shadow daggers (2.5× from behind) and the rift chakram, which flies back to you.
The subway
Take the stairs by the square down to a dark station: wrecked trains, storerooms, and the Tunnel Horror at the end of the line.
