Where to Find a Red Keycard
Red cards are the top of the chain. Every one in the world was either pulled from a blue puzzle room, grabbed at Arctic Research Base, or bought — and each card only survives two swipes.
Every red card source
- Airfield — blue puzzle loot room
- Train Yard — blue puzzle loot room
- Power Plant — blue puzzle loot room
- Water Treatment Plant — blue puzzle loot room
- Arctic Research Base — on a box behind the blue garage door (no fuse needed)
- Large Oil Rig — blue card room
- Underwater Labs — blue-tier modules
What a red card opens
Launch Site's main building route, Military Tunnels' final door, Missile Silo's underground levels, Large Oil Rig's red room, and red modules in Underwater Labs.
Run a red puzzle
- Launch Site 2 fuses · 25 for the puzzle; full rad suit + water for the main building
- Military Tunnels 1 fuse · 25 rad protection
- Missile Silo no fuse · 25 rad protection
- Oil Rig (Large) no fuse · None — bring combat gear instead
- Oil Rig (Small) no fuse · None — bring combat gear instead
- Underwater Labs 2 fuses · None — bring diving/sub logistics instead
Red cards — quick answers
- Why did my red card break so fast?
- Red cards only last 2 swipes — half the durability of green and blue. Never swipe a red door 'just to look'.
- What's the easiest red keycard?
- Arctic Research Base: one blue card, no fuse, and the red card sits on a box behind the left garage door. Watch for the scientist patrols.
