Thorough exploration of the scenarios in the recently released title in the survival horror franchise requires attention to detail from users. Dentro of Centro of Cuidados Rhodes Hill facilities, locked safes store essential resources for the progression of the main campaign and for improving equipment.
The system for opening these compartments requires entering exact combinations into a rotating metal dial. Mechanics establish that movements to the left follow a clockwise direction, while movements to the right follow a counterclockwise direction.

The location of the compartments covers different sectors of the game map:
– Bar and Lounge with old coins.
– Sala of Exame with old coins.
– Sala of Espera with compartment already unlocked.
– Porão from Forno containing map and ammunition.
– Câmara of Esterilização ARK with medical and offensive items.
– Lounge0 of Lounge1 ARK with components for creating grenades.
Obtaining all items stored in these locations guarantees unlocking the exploration achievement. Progress tracking occurs automatically in the menus on current gaming platforms.
First compartments in the care center
The compartment located at Bar and Lounge appears in the early hours of the campaign, located on the second floor of the medical complex. The area has a significant amount of enemies, which forces the player to clear the perimeter before trying to enter the combination, which consists of left ten, right eighty and left thirty. The file that confirms this sequence is positioned nearby, and opening it guarantees three old coins, in addition to facilitating access to Grace’s pistol.
At Sala of Exame, accessible from the east lobby, the user will find another safe positioned in the right corner of the room. The correct sequence for unlocking the metal door requires the movements right thirty, left ten, and right fifty, as indicated by a document left on an adjacent table. The reward delivers three more ancient coins, totaling six units at the beginning of the journey, which allows for quick acquisitions of Salão improvements.
Atypical situation at the main reception
Sala of Espera presents a variation on the standard mechanics for exploring the security compartments. The safe positioned behind the main service counter already has the door unlocked.
This condition eliminates the need to search for passwords or text documents in the scenario. The player only needs to interact with the object to collect the two ancient coins left inside.
The visual narrative suggests that another character looted the place previously. Interacting with this specific object normally counts towards the progression of the main achievement associated with the vaults.
Secrets hidden in the facility’s basement
Accessing Porão from Forno requires solving a prior puzzle involving a joint plug for the stacker room. The safe in this area is in a side position and requires a specific password.
The combination right sixty, left forty and right eighty is engraved on a deformed cabinet in the same sector. Entering the numbers correctly releases the locked compartment.
The interior stores ten pistol bullets, essential for direct confrontations that occur in the dark underground corridors. The feature helps keep your inventory stocked against local threats.
In addition to the ammunition, the player acquires the raccoon map. Este document marks the exact location of all collectible statues scattered throughout the medical complex.
Advanced Supplies in the Lab
The campaign’s progression takes the characters to the ARK laboratory, a zone infested with lickers and advanced biological weapons. The safe located at the bottom of Câmara of Esterilização requires the sequence right ten, left ninety and right twenty.
Opening this compartment provides a medical injector, fifteen pistol bullets, and a Molotov cocktail. The codes for this area are stored in Repositório of Bioweapons zero five.
Tactical resources in the control room
The second safe in the ARK complex is located at Sala, Controle, Monitores, an area adjacent to the main lobby. The corresponding password requires the movements left fifty, right sixty and left eighty.
The reward includes a medical injector, a vial of acid and an empty bottle. Combining the acid with the bottle allows you to create improvised grenades to clear blocked routes.
Password changes on maximum difficulty
Selecting mode Insanidade substantially modifies the exploration experience, keeping the location of the safes intact but changing all numerical combinations to test users’ memory. No Bar and Lounge, the new sequence becomes right twenty, left fifty and right thirty, while Sala of Exame now requires left fifty, right thirty and left ninety. The Porão Forno magazine adjusts its latch to left seventy, right fifty, and left twenty. Nas advanced facilities, the Câmara of Esterilização demands left eighty, right fifty and left zero, and the No Bar0 of No Bar1 of No Bar2 requires right twenty, left zero and right seventy. No Bar3 of No Bar4, in turn, presents your safe completely empty in this difficulty, removing old coins from easy access and forcing much more rigorous resource management from the first minutes of play.
Requirements for the Exploration Achievement
Obtaining the achievement Nenhum Cofre IS Seguro occurs after opening the six main compartments during the regular campaign. Trophy synchronization happens in real time on desktop and computer platforms.
Economy system and weapon improvements
The old coins collected in the initial compartments function as the main currency of exchange in Salão of Centro Rhodes Hill. Accumulating six units allows you to double the ammunition capacity of the basic firearms used by the protagonists.
Another investment option available at Salão increases the pistol’s base damage by twenty percent. Prioritizing these improvements in the early hours optimizes combat performance and reduces ammunition consumption against common enemies.
Purchased upgrades remain active in Novo Jogo Mais mode. Efficient management of ancient coins defines the difficulty curve of mandatory confrontations throughout the narrative.
Inventory Management and Rotation Tactics
Strategic use of supplies found in the ARK laboratory vaults determines the survival rate in the final sections of the campaign. The Molotov cocktail obtained from Câmara from Esterilização serves as the main tool for clearing narrow corridors occupied by multiple lickers, saving conventional ammunition. Medical injectors instantly restore characters to full health, functioning as an emergency resource during boss battles. The empty bottle, when combined with chemical fluids, creates area weapons that neutralize groups of armored enemies. Inventory space planning requires the player to return to storage chests frequently to organize newly acquired items.
The mechanics of rotating the safes display require precision in control or keyboard commands. The system starts in automatic mode, but manual manipulation guarantees greater control over the entry of numbers. The technical recommendation advises to go through the previous numbers during the second rotation to avoid accidentally restarting the sequence. Practicing in already open compartments helps you understand the sensitivity of the dial before attempting to open safes in areas patrolled by enemies. Password confirmation only occurs after pressing the verification button, allowing corrections if the user accidentally reverses the turning directions.
