The CRFHSRB Redleaf keycards are essential for accessing the Redleaf Abandoned Base in StarRupture, especially if you’re chasing after valuable rewards. But before you can dive into the loot, you’ll need to gather three specific keycards and an override access card.
This guide will lead you through the process of locating all necessary keycards to make the most out of your adventure.
Where to Find the Redleaf Abandoned Base in StarRupture
The Redleaf Abandoned Base is tucked away in the northeastern section of the map. Below, I’ve included a helpful image that marks the locations for the keycards you need to find.

Inside the base, you’ll need to hunt down three keycards along with one override access card:
- Eng. Perkins’ Security Clearance Card (P)
- Dr. Ellis’ Security Clearance Card (E)
- Dr. Diaz’s Security Clearance Card (D)
- Override Access Card (OA)
Where Can You Find the Redleaf Override Access Card?

Your first priority should be the override access card, found atop a large red building right in the center. This spot is hard to miss! Climb the platforms to reach the peak, where you’ll find the card on a dead body, along with extra loot for your collection.
How to Locate Dr. Ellis’ Security Clearance Card?

From your first location, glance down to spot a small red room on the ground. This room will have red stripes on its sides. Use the access card to unseal the door, revealing your first blue clearance card.
What About Dr. Diaz’s Security Clearance Card?

Exit the red room and take the stairs to your left. Stay on your left side to dodge any Goliath threats. Sprint your way toward a blue building; enter through the main door, and take the stairs to reach the second floor. There, you’ll find Dr. Diaz’s Security Clearance Card casually resting on a table.
Where Can You Find Eng. Perkins’ Security Clearance Card?

The last keycard is located on the western fringe of the base. Make your way there based on the marked location in the image above. You’ll find a smaller blue-painted building where the security clearance keycard is waiting for you on a table.
What Loot Awaits You at the Redleaf Abandoned Base?
The thrill of looting the Redleaf Abandoned Base is matched by its dangers. To gain access, climb the nearby red building and leap over to the blue structure, where several doors will be locked.
Insert the three keycards correctly to unlock the second of the two locked doors, revealing fantastic rewards, including:
- Turbine Blueprint
- 60 War Bonds
- Electromagnetic Coil Blueprint
- Hardening Agent Blueprint
- Valve Blueprint
- One Frame Memory Module
