Rust Red Keycard
The top card — the one that opens the best loot at the big monuments.
Where to get it
Red keycards sit behind a blue-card door, almost always at the larger monuments. You spend a blue card to reach the room that holds a red one, then use the red for the final loot room.
Blue-tier puzzles
Completing a blue-card puzzle at Airfield, Arctic Research Base, Missile Silo, Power Plant, Train Yard or Water Treatment rewards a red card.
Bandit Camp
The Scrap 4 Sale vendor sells a red keycard for 40–160 scrap — the safe route if you'd rather farm scrap than run a puzzle chain.
