Step-by-Step Solution

⚠ Step path being confirmed: Arctic Research Base has a detail or two not yet locked down. The requirements and loot below are confirmed; the exact in-room route is being verified in-game. Trust the live game and we'll firm this up.
1

Enter the base and push through the entry hallway — scientists guard the interior, so this is a fight.

2

Locate the fuse box in the main facility and insert your fuse to power the locks (some reports say power is already supplied — bring one to be safe).

3

Swipe your Green keycard to open the secondary lab areas (more scientists; military crates here).

4

Reach the Blue keycard reader guarding the secure vault and swipe.

5

Collect the Red keycard and the vault loot.

Loot & Reward

Keycard-door loot respawns every 30 minutes — far faster than open crates, so a puzzle you can reach is renewable income.

Treat it as a combat run, not a stealth puzzle — the scientists won't let you tiptoe through.
The exact fuse requirement and reader order are still being confirmed; the card progression (green → blue → red reward) is solid.
