The CRFHSRB Redleaf keycards, required for opening the Redleaf Abandoned Base, can be immensely useful in StarRupture if you’re looking to find lucrative rewards.
The Redleaf Abandoned Base has hidden treasure that you can find. However, you’ll first need to find the three keys, along with an additional access card.
This guide will help you to find them all.
Redleaf Abandoned Base location in StarRupture
The Redleaf Abandoned Base is located in the northeastern part of the map. I have marked the keycard locations in the image below.
Once you’re in the base, you’ll need to find three keycards and one additional override access card.
- Eng. Perkins’ Security Clearance Card (P)
- Dr. Ellis’ Security Clearance Card (E)
- Dr. Diaz’s Security Clearance Card (D)
- Override Access (OA)
Redleaf Override Access Card location

This is the first item you need to find. The access card is located on the top of the large red building in the middle area. The red building is pretty easy to spot, and you have ot use the platforms to reach the top. The access card will be on a dead body, along with some more loot.
Dr. Ellis’ Security Clearance card location

From the first spot, look down, and you’ll find a small red-colored room on the ground. It will have red-colored stripes on its side. Unlock the door and get the first blue card.
Dr. Diaz’s Security Clearance Card Location

Exit the room, and take the stairs on your left. Keep moving to your left, and be careful about the Goliath. You can either engage it, but the best option is to use your sprint to find a blue building. Go through the main door and take the stairs to reach the second floor. Dr. Diaz’s Security Clearance card will be on the table.
Eng. Perkins’ Security Clearance Card location

The final keycard can be found on the western edge of the location. Keep moving to the western side based on the marked location on the image above. You’ll come across another small building with a coat of blue paint, where the security clearance keycard will be on the table.
All Redleaf Abandoned Base loot in StarRupture
The Redleaf Abandoned Base is one of the most dangerous areas to loot. To enter the base, climb up the red building beside it and reach the top floor. Then jump to the blue building, and you’ll come across a couple of locked doors.
Place the three keycards in the correct slots. This will open the second of the two locked doors, and here’s what you’ll obtain.
- Turbine Blueprint
- 60 War Bonds
- Electromagnetic Coil Blueprint
- Hardening Agent Blueprint
- Valve Blueprint
- One Frame Memory Module
