But once you do it, you unlock a hidden room with a Health Upgrade inside — and those are some of the most valuable pickups in the game.

This guide breaks down exactly how to solve the Atlantis Cafe cash register puzzle in Control Resonant, step by step.

Where to Find the Atlantis Cafe Cash Register in Control Resonant

Where to Find the Atlantis Cafe Cash Register in Control Resonant

There are two Atlantis Cafe locations in Control Resonant. The one with the cash register puzzle is in The Park zone. Go to the southeast corner of The Park, directly in front of the Research Site.

You will spot it easily. It is the only shop on the block with its lights still on. Every other storefront is dark. As you get closer, the game will add a question mark on your map to mark it as a point of interest.

Walk inside and go behind the counter. You will see a cash register that asks you to enter a four-letter code. You cannot guess your way through this one — you need to find the clues first.

Note: The Downtown Atlantis Cafe has a completely different puzzle. That one involves turning on appliances in size order. This guide is only for The Park location.

How to Find the Atlantis Cafe Cash Register Code in Control Resonant

To work out the code, you need two things from the counter and then four leaflets from the tables around the cafe.

Step 1 – Pick Up the Two Documents on the Counter

Before you do anything else, grab both documents sitting on the counter. Do not skip this step.

• The Menu – This lists all the drinks available at Atlantis Cafe. Each drink is assigned a specific letter (A, B, C, or D).
• The Handwritten Note (Table Reservation Note) – This shows which regular customers have reserved which tables, and crucially, it gives you the order to follow for the code.

The Handwritten Note lists the reservation order as Tables 1, 5, 4, 2. That sequence is what you will use to arrange the final letters.

Step 2 – Check the Leaflets on the Four Tables

Now walk around the cafe and find the leaflets sitting on top of Tables 1, 2, 4, and 5. Each leaflet shows what drink that table’s regular customer orders. You need to match each drink to its letter from the Menu.

Here is exactly what each table says and what letter it maps to:

Table Number	Drink Ordered	Letter on Menu
Table 1	Iced Coffee	B
Table 5	The Spiciest Chai	D
Table 4	Espresso	A
Table 2	Caramel Latte	C

Step 3 – Put the Letters in Reservation Order

The Handwritten Note says the reservation order is Tables 1, 5, 4, 2. So you just take the letters for those tables in that exact order:

• Table 1 = B
• Table 5 = D
• Table 4 = A
• Table 2 = C

That gives you the code: BDAC.

Control Resonant Atlantis Cafe Cash Register Code – BDAC

Go back behind the counter and interact with the cash register. Enter B – D – A – C in that exact order.

The moment you enter the correct code, a wall panel beside the counter slides open. This reveals a hidden stairway going down into one of the game’s Secret Organization hideouts.

If the code is not working, double-check you are entering it in the reservation order (1, 5, 4, 2) and not just alphabetical order. The sequence matters.

Atlantis Cafe Secret Hideout Rewards

Head down the stairway and search the room before you leave. There are three things to collect inside:

• Health Upgrade Point – Found at an ice cream stand inside the room. This is the main reason to bother with this puzzle. Health Upgrades directly increase Dylan’s maximum health, making tougher fights much more forgiving.
• Notice of Decommissioning – A collectible lore document.
• F**k You, Larry – Another collectible lore document.

The Health Upgrade is the big one. Control Resonant does not hand these out generously, so grabbing every single one you can find early in the game makes a real difference. If you are tracking the Secret Organization storyline, the lore documents also add some useful context to what is happening behind the scenes.

Completing this hideout also counts toward the Backroom Espionage achievement, which requires you to open all six Secret Hideouts in the game.

All 6 Secret Hideout Locations in Control Resonant

The Atlantis Cafe in The Park is one of six Secret Hideouts hidden across the game world. Each one contains a Health Upgrade and lore documents. Each one also has a puzzle you need to solve to get inside. Here is a quick overview:

• Downtown – Atlantis Cafe: Appliance puzzle. Turn on six appliances in size order (radio, coffee machine, coffee brewer, soda machine, microwave, refrigerator).
• West Incursion Zone – Urban Fresh Mart: Cash register code puzzle. The code is 1213, found by reading the soda machine lights.
• Central – Laundromat (WEAR’EM & WASH’EM): Painting interaction puzzle.
• The Park – Atlantis Cafe: Cash register code puzzle. The code is BDAC (this guide).
• The Unknown – Pulse Fitness Gym: Gym equipment puzzle. Follow the workout plan in the locker room note.
• Art Gallery (Konstig Painting area): Painting puzzle with interactive canvases.

If you want to unlock Backroom Espionage, you need all six. Do not leave a zone without checking your map for any remaining question marks.

Tips for Exploring The Park Zone in Control Resonant

The Park is one of the denser zones in the game for optional content. A few things worth knowing before you dig in:

• Always read notes before interacting with anything in a puzzle room. The solution is almost always written down somewhere inside.
• The Atlantis Cafe stands out because its lights are on. If you see a lit-up storefront in a dark block, go inside.
• Question marks on the map are always worth investigating. They are how the game flags secrets.
• Health Upgrades are rare. There are only a handful in the entire game. Do not skip the secret hideouts.
