Electric fuses
The humble fuse is the real key to every monument: without one in the fuse box, no amount of keycards opens anything. Here's where they spawn and how the circuits consume them.
Where fuses spawn
- Barrels — the roadside standby; components drop constantly.
- Basic and tool crates — at every monument.
- Outpost & player vending machines — usually cheap in scrap.
- Recycler output — no; fuses don't come from recycling. Loot or buy only.
How puzzle circuits use them
Every land-monument puzzle follows the same electrical logic: find the fuse box, slot a fuse, flip the associated switch or timer, and the card readers on that circuit go live. The fuse drains while the circuit is powered and is consumed — plan one fuse per puzzle, minimum.
Fuse counts by monument: most green puzzles need 1; Airfield and Launch Site need 2; Arctic Research Base and the Oil Rigs need none. Each guide's manifest lists the exact count — see all puzzle guides.
The standing kit
Experienced players carry 2 green cards, 1 blue card, and 2 fuses as a default loadout. That kit runs any green puzzle plus the blue puzzle it unlocks, without a resupply trip.
Fuses — quick answers
- Where do electric fuses come from?
- Barrels and basic crates along roads and at monuments, tool crates, and Outpost/player vending machines. They're a common component — a short road run usually turns one up.
- Do fuses get used up?
- Yes. A fuse placed in a puzzle fuse box drains while the circuit is live and is consumed — you don't get it back. Bring one per puzzle, plus a spare if the run has a timer you might miss.
- Can I craft an electric fuse?
- No — fuses are loot-only. If you're dry, check barrels along the road or buy one at Outpost.
- Why did the puzzle door stop working mid-run?
- Most puzzle circuits run on a timer once switched on. If the timer lapses before you swipe, the door de-powers and the fuse keeps draining — reset the switch and move faster on the next attempt.
