Sewer Branch Puzzle Walkthrough
Step 1: Find the Primary Structure
Head to the main building near the parking area. Inside, locate the fuse box.
Step 2: Install the Fuse
- Place your Electric Fuse into the fuse box.
- Without it, the Green Keycard door will remain locked.
Step 3: Activate Power
- Flip the nearby power switch.
- This powers up the electronic systems and unlocks the card reader.
Step 4: Enter the Sewer Tunnels
Exit the building and move toward the underground pipelines.
Look for the large, corroded pipes leading into the tunnel system.
Step 5: Use the Green Keycard
Deeper inside, you’ll find a locked door with a card reader. Swipe your Green Keycard to gain access.
Step 6: Collect the Loot
Inside the puzzle chamber:
- A Blue Keycard (your main objective).
- Military crates with weapons and gear.
- Components, scrap, and extra loot spawns.
The Blue Keycard will let you progress to higher-tier monuments such as the Airfield and Power Plant.
Additional Loot Areas in Sewer Branch
- Recycler: Located near the vehicle lot.
- Oil Processing Facility: Found underground for refining crude oil.
- Scattered Barrels and Crates: Extra scrap and components.
Strategy Tips
- Stay Alert: Tight corridors make ambushes likely.
- Carry Extra Fuses: Prevents wasted trips if one burns out.
- Time Your Exit: Combat often breaks out once loot is claimed.
- Recycle Before Leaving: Convert road signs, tanks, and other materials into scrap.
Conclusion
The Sewer Branch puzzle is one of the most reliable ways to get a Blue Keycard early in Rust. With a fuse, Green Keycard, and basic protection, you can complete the run in minutes. On high-population servers, expect competition and ambushes in the tunnels, but with careful planning you can secure loot consistently and gain a strong early-game advantage.
