StarRupture Anti-Radiation Covers Blueprint Location
The Anti-Radiation Covers Blueprint is a vital piece of survival tech located in the LMB “Yellowstone” outpost, situated inside a treacherous gorge at the very top of the map. Getting your hands on this schematic involves a multi-step keycard puzzle and navigating through some severe environmental hazards.
Where to Find the Anti-Radiation Covers Blueprint in StarRupture
To secure this blueprint, you will need to travel far North to the Yellowstone gorge, locate a master Red Keycard, and gather three separate sector cards to unlock the final room. Because of the sulfur coating the ground and the heavy alien presence, this is one of the more dangerous blueprint runs in the game.

1. Preparing for the Journey to LMB Yellowstone
Since base locations vary, use the starting ship as your universal landmark and head to the very top of the map. Unless you have teleporters set up, this will be a long run. I highly recommend attempting this run directly after a Rupture. The gorge floor is covered in hazardous sulfur, and a Rupture will clear out the massive swarms of aliens, making your search significantly safer.

2. Entering the Gorge and Finding the First Keycard
Start your approach on the left side of the gorge and work your way to the right. Follow the main path down into the gorge until you reach the first building. Head down the stairs, cross over to the structure, and go inside. Here, you will find the first of three sector keycards required for the final door, alongside a grim audio log about the outpost’s crew.


3. Locating the Red Master Keycard
After grabbing the first card, head up the stairs and follow the path until you spot the next cluster of buildings. While there is a massive amount of loot in this area, you should prioritize getting the blueprint first before the aliens start spawning again. Head around the main building in this cluster, go through the open door, turn left, and head straight. You will find a Red Keycard. Grab it, as this master key is required to open the doors guarding the remaining cards.



4. Securing the Remaining Two Keycards
Head back out of the building where you found the red card and turn left. Look to your right, and you will see the next building down on the ground. You can reach it by taking the stairs or simply jumping onto the roof and dropping down. Use the Red Keycard to unlock the door, head inside, and grab the second sector keycard.


From there, look straight toward the distant gap in the terrain to spot the final building. Head down to it, unlock the door, and grab the last keycard sitting on the table.



5. Unlocking the Blueprint Room
With all three sector cards and the red master card in your inventory, retrace your steps back to the building where you originally found the Red Keycard. Head inside and climb the ladder to the second floor. Insert the three sector keycards into the locked door terminal to open it.



Inside, you will find the chest containing the Anti-Radiation Covers Blueprint, as well as a rather dramatic audio log revealing a betrayal between crew members Anastasia and Scott. Once you have the blueprint, you can safely sweep the rest of the outpost for loot before heading home.
