Airfield — puzzle circuit

Airfield is where the chain starts asking for a real loadout: two cards, two fuses, and a timer that punishes slow routes. Walk it once with this circuit in mind and the run becomes routine.

Before you go

Green card, blue card, 2 electric fuses, and ~10 rad protection. Bring a weapon — the loot room is worth contesting and other crews know it.

The route

Garage building, left side. Enter the garage complex and head for the right-hand room: place fuse #1 and activate the timer. The clock is now running — move.
Down the tunnel entrance. Exit and drop into the tunnel system, then turn right at the junction.
Green door. Swipe your green card to open the gate into the powered section.
Fuse #2. Just beyond, place your second fuse in the tunnel fuse box — this arms the blue reader.
Blue door — swipe and loot. Swipe the blue card and clear the room: 7 crates and the red keycard. The card is the priority; crates second.

After the run

That red card only survives two swipes — spend them deliberately. Military Tunnels and Launch Site are the classic destinations; both want more preparation than Airfield did.
