Control Resonant Guide: How to Get Clearance Level 6 Keycard

The clearance level system is back in CONTROL Resonant, and Clearance Level 6 is the one most players end up hunting for mid-game. Unlike some keycards that land in your inventory automatically, this one is tied to a side story that's easy to walk past if you're pushing straight through the main missions. Two locked offices in the Central Executive sector stay sealed until you track it down, and one of them holds rare crafting resources worth having.

When does Clearance Level 6 become available?

The keycard doesn't appear until Act 3. At the start of that act, Dylan receives a quest called Zoe's Briefing, which opens a side story called New Growth. This investigation follows Dylan as he traces a missing researcher, Dr. Underhill, and her work involving the Mold. The whole side story is optional content, but the keycard is sitting right at the beginning of it.

How to get the Clearance Level 6 keycard

Once New Growth is active, its opening objective sends Dylan to the FBC Base in The Park zone. Head there and look for the table holding Dr. Underhill's investigation materials. The Clearance Level 6 keycard is sitting on that same table. Pick it up and Dylan permanently gains Level 6 access across the entire Oldest House.

Here's how you get it:

1. Reach Act 3 and accept Zoe's Briefing
2. Start the New Growth side story
3. Follow the first objective to the FBC Base in The Park
4. Search the table with Dr. Underhill's files
5. Pick up the keycard

Where does Clearance Level 6 actually work?

The keycard opens two offices on the upper floor of the Central Executive sector in the Oldest House. Here's what each one contains:

Dr. Underhill's office is a mandatory stop if you want to advance the New Growth investigation. The second office is worth opening regardless, since the container inside drops rare resources used for crafting and upgrading.

Can you miss the Clearance Level 6 keycard?

Yes. Players focused on the main story can reach late-game without ever triggering Zoe's Briefing or stepping into The Park's FBC Base. The good news is that the keycard doesn't disappear. Return to Act 3 content at any point, start New Growth, and the table in The Park will still have it waiting.

What else should you unlock while exploring?

The Oldest House holds a lot of optional content beyond the Central Executive offices. Puzzle solutions scattered across zones reward Secret Hideouts and Health Upgrades, and several of them are easy to walk past. The Control Resonant guide collection covers the full range of these, from the Evacuation Zone Art Gallery painting puzzle to the Central Laundry binary washing machine puzzle. If you're chasing 100% completion, the full Control Resonant trophy list breaks down every achievement and what you need to unlock the Platinum.
