Military Tunnels Puzzle Guide — Red Card Route

Military Tunnels is a gear check disguised as a puzzle. The circuit itself is simple — one fuse and three swipes — but you solve it while trading fire with scientist squads in tight corridors.

Before you go

Green, blue, and red keycards, 1 electric fuse, ~25 rad protection, and a genuine combat loadout — rifle or SMG, meds, and ammo to spare. Every card matters: don’t start the run missing one.

The route

1. Enter via the right door. From the surface checkpoint, take the right-hand entrance into the tunnel system.
2. Armory — fuse in. Fight your way to the Armory and place your fuse in the marked fuse room.
3. Through the fence gap. Slip through the hole in the fencing to reach the storage section.
4. Green door. Swipe green at the Storage door and keep clearing.
5. Laboratory switch. Flip the switch in the Laboratory — this arms the final circuit.
6. Rail car elites. The center rail car carries elite crates mid-route — loot them; they’re often worth the trip alone.
7. Blue door, then red. Swipe blue at the Laboratory door, then hit the final timed red door: 3 elite, 2 military, 2 normal crates. The timer is running — loot the elites first.

After the run

No recycler inside — haul your components out to the nearest monument recycler. Scientists respawn on a timer, so re-runs each wipe are viable once you know the clearing rhythm.
