People climb buildings. The AI’s people go up onto roofs to fire at ships and to spot, and you can too: jump at a wall, climb with the stick, and press A at the top.
Tunnels. Real tunnels from the map are routes under the ground. People walk and ride through them and duck into them to escape ships, and on St John’s Wood they take the Tube from its stations. Press Y at an entrance to go through one yourself. Entrances are drawn on the surface and marked on the minimap.
Bridges and water. Roads on bridges now sit on the deck, and ships can fly under bridges over water. Nothing stands on water any more, so moored ships and river surfaces no longer count as cover or get in the way.
More buildings worth taking. White buildings turn orange from 200 m² (was 300), which roughly doubles the targets on the rural maps.
Radio. Three new songs and 143 new DJ lines, and the DJs no longer repeat their chat or predictions within a show.
New priors and pars for every map. Also, when you’re flying a ship, someone you’ve boxed no longer vanishes when the fleet loses sight of them.
