Starting threat by area
| Area | Expected starting AI threat |
|---|---|
| Air Base Exterior | Critical |
| Air Base Bunker | Extreme |
These are the guide’s pre-engagement danger levels. Subareas retain their own ratings; combat can escalate conditions. Extreme is a separate level above Critical.
Approaches and surroundings
Inhospitable wilderness lies to the west, together with hidden missile bunkers, a large toxic containment pool, rural hamlets and smaller NK supply depots. Cliffs constrain the eastern approach. Recon teams report access from elevated woodland to the south, but infiltration from any direction is difficult; finding gaps in the concrete wall requires avoiding watchtower guards.
Surface facilities
The defended compound contains a hospital, helipad, jet runway, barracks, supply depots and an ornate command-and-control building. Guards and higher-value targets are present.
Underground bunker
Large bunker doors sit in the southern hillside. The guide describes radar reconnaissance of buried structures, concealed tunnels and potential hazards, including a tunnel network with a larger footprint than the surface base. It does not provide a tested entrance-to-exit route.
