The Nuclear Missile Silo is less a puzzle than a descent: one red swipe at the surface opens five underground levels of scientists, crates, and — at the very bottom — a live warhead in its launch cradle.
Why you’re here
Crate volume. Roughly 30 crates spread across the underground levels, an elite crate in the pickup truck at the cavern floor, and scientist drops the whole way down. For a single red-card swipe (no fuses), the silo pays out like a monument twice its footprint.
The layout
Surface radiation runs 10–25 protection; underground holds at the 25 band. Below the blast doors: Level 1 (lobby and storage), Level 2 (passages and admin — the heaviest scientist concentration), Level 3 (living quarters), Level 4 (computer room), and the Level 5 cavern with the warhead, missile base, and diesel barrels. Exit runs back up by elevator to Level 2, then stairs to the security checkpoint’s blast door.
