What to know
- All three key cards are required before endgame blueprints become accessible
- The final unlock is in the central satellite building, not a side structure
- You must climb a ladder and manually insert all key cards
- The unlocked area contains multiple high-impact endgame schematics
After completing the full Satellite Point of Interest key card chain, Star Rupture finally opens its true endgame layer. The blueprints hidden behind the satellite’s central override system are not optional upgrades — they are foundational components for advanced crafting, automation, and late-game systems.
This guide explains exactly how to unlock the final area and highlights the endgame blueprints you should not leave behind.
Location of the main building in CRFHSRB
In the CRFHSRB area, you can find the main building compound as shown in the map below.
Look for the satellite tower antenna to navigate to this area. From your base, this is towards the north-east.
Returning to the central satellite building
Once you have collected every required key card, return to the central building of the Satellite POI. This is the same hub area you passed through earlier, but it now serves a new purpose.
The game does not automatically guide you here, so manual backtracking is required.
How to unlock the main endgame blueprint area
Step 1: Enter the central satellite building
Move into the central structure where the satellite’s core systems are located. This building becomes fully relevant only after all key cards are obtained.
Step 2: Locate and climb the ladder
Use the Red Key Card here to unlock the building.
Inside the building, look for a ladder leading upward. This vertical path is easy to miss if you’re focused on ground-level rooms.
Step 3: Find the key card insertion slot
At the top of the ladder, you’ll see a dedicated slot designed for multiple access cards. This is not a door or console — it is a manual insertion point.
Step 4: Insert all three key cards
Interact with the slot and insert every key card you collected. The unlock only triggers if all required cards are present.
Step 5: Enter the newly unlocked area
Once activated, the main endgame blueprint area opens. This room contains several of the most important schematics in the game. Spot the blue storage box and unlock endgame blueprints.
StarRupture endgame blueprints you should not miss
The unlocked area holds multiple blueprints that define late-game crafting and system progression. Missing these will severely limit your options moving forward. All the blueprints you can get from here:
- Valve blueprint
- Electromagnetic Coil blueprint
- Hardening Agent blueprint
- Turbine blueprint
Why these blueprints matter long-term
These schematics are not simple upgrades — they unlock entire crafting branches. Many late-game items either directly require these components or are balanced around the assumption that you have them.
Skipping this room can soft-lock progression, forcing unnecessary grinding or backtracking later.
Common mistakes players make at the satellite
- Leaving the Satellite POI after collecting key cards
- Missing the ladder inside the central building
- Assuming blueprints unlock automatically
- Picking up only one blueprint and exiting early
The game expects you to manually trigger the final unlock and thoroughly loot the room.
Best practice before leaving the satellite POI
Before exiting the area:
- Double-check every blueprint pickup prompt
- Confirm all schematics are unlocked in your crafting menu
- Fully explore the room for secondary interactables
This ensures you never need to return to the satellite again.
