The AOC Secret Archives is one of the most lucrative and complex locked locations introduced with the Airport map in Arena Breakout: Infinite. Accessing it is not as simple as swiping a keycard – players must first solve a multi-step security puzzle inside the AOC Control Center before the AOC Secret Archives Keycard can even be used.
This guide explains exactly how to get into AOC Secret Archives, where to go, how the puzzle works, and why the loot makes this keycard one of the most expensive and valuable in the entire map pool.
What Is the AOC Secret Archives Keycard?
The AOC Secret Archives Keycard unlocks a high-value sealed room inside the AOC Control Center backrooms on the Airport map. This room contains:
- 2 safes (including an electronic safe).
- Document box.
- Rare keys and valuables + Red Items.
- Strong risk-to-reward value for late-game players.
However, unlike standard locked rooms, you cannot access it immediately at match start, even if you already have the keycard.
AOC Secret Archives Location (Airport Map)
To begin, you must travel to:
📍 Airport Map → Central Main Building → AOC Control Center
Step-by-step location path:
- Enter the main central building of the Airport map
- Use any of the three main entrances
- Be aware: opening these entrances announces your action to the entire map
- Move to the first floor Control Tower area
- Enter through one of the available breaches or doorways
- Drop into the small side room via the hole in the wall
- From there, proceed into the locked upper ring backroom area
At this point, you’ll encounter a problem.
Why the AOC Secret Archives Are Locked at Match Start
Even if you:
- Blow through walls
- Reach the correct hallway
- Already own the keycard
➡️ The two doors leading to the upper ring and archive area are locked by default.
This is intentional. The developers introduced a new environmental puzzle mechanic that must be completed first.
How to Unlock the AOC Control Center Backrooms (Puzzle Guide)
🔐 Step 1: Find the Yellow Code Books
You need to locate at least two yellow code books.
- They spawn on tables throughout the Control Center
- Each book contains: One letter
- One number
Example:
A = 4
C = 9
You technically only need two books, not all three.

🔐 Step 2: Go to the Observation Room (Upstairs)
Once you have the code books:
- Head upstairs
- Enter the Observation Room
- Open the door inside
- You’ll see an Access Terminal directly in front of you
🔐 Step 3: Use the Access Terminal
The terminal:
- Displays three letters
- Requires you to input three numbers
How the code logic works:
- Each letter corresponds to a number from the yellow books
- If you have: 2 books → only 10 possible guesses
- 1 book → 100 guesses (not recommended)
- 0 books → 1000 guesses (very inefficient)
You can:
- Retry unlimited times
- Brute-force the final digit if needed
Once the correct combination is entered:
✅ Both locked doors unlock
✅ Access to the upper ring and electronic safe area is granted
