Airfield is the blue puzzle that demands the most planning — two fuses and both lower cards — and pays the most back: seven crates and a red keycard in the underground loot room.
Why you’re here
The red keycard plus the richest blue-tier loot room. Airfield’s puzzle runs partly underground through a tunnel system, which keeps the loot room safer from drive-by swipers than surface puzzles.
The layout
A long runway flanked by hangars, a control tower, and a garage complex. The puzzle starts in the garage building (fuse + timer), then descends into the tunnels where a green door gates the second fuse box and the final blue reader. Light radiation around parts of the monument — ~10 rad protection keeps you comfortable.
