CRACK Game Walkthrough: All Upgrades and Both Endings

CRACK is a first-person adventure and incremental simulation game developed and published by Rafoli. Released for Windows PC on October 26, 2026, the game supports cooperative play for up to four players, although solo players can also explore the laboratory and progress through its objectives.

The central objective is to excavate a gigantic, mysterious egg inside a laboratory, collect and sell the recovered materials, and reinvest the earnings into better equipment. As you dig deeper, the work becomes more complicated. New materials require improved tools, automated machines help transport resources, and dangerous reactions can disrupt your progress.

Beyond excavation and resource management, CRACK hides a larger mystery within its laboratory. Players can discover a UV flashlight, investigate a restricted room, collect hidden messages and uncover a secret escape route. The game features two endings: processing the specimen as instructed by the facility or helping it escape.

This walkthrough covers the main progression path, essential upgrades, automation, specimen reactions, hidden secrets, both endings and all 40 achievements listed in the supplied game guide.

CRACK Progression Roadmap: What to Do First

The easiest way to progress in CRACK is to follow the game’s objective list while investing your earnings carefully. Early excavation provides the money needed for better tools, while later upgrades unlock automation and access to deeper sections of the specimen.

Follow this general progression order:

• Step 1: Complete the introductory briefing and begin excavating the giant egg.
• Step 2: Collect broken shell fragments in buckets and deliver them to the Resource Depot.
• Step 3: Purchase the Mk 1 Shovel to excavate the membrane beneath the outer shell.
• Step 4: Unlock the Mk 2 Shovel to access the tissue layer.
• Step 5: Deposit approximately $70 worth of tissue to unlock Workbot Storage.
• Step 6: Purchase Collector Bots and Delivery Drones to automate resource handling.
• Step 7: Upgrade your equipment and vehicles while collecting Chalazite for Workbot upgrades.
• Step 8: Monitor specimen agitation and use the Sedative Application Terminal when required.
• Step 9: Build supported scaffolding to reach elevated areas and the ventilation shaft above the Breakroom.
• Step 10: Find the UV Flashlight, investigate the Redacted Room and collect hidden messages.
• Step 11: Explore the facility’s secrets and choose between the specimen-processing ending and the secret escape ending.

Following this order helps you avoid spending too much money on unnecessary equipment before your excavation operation becomes profitable.

CRACK Full Game Walkthrough: Getting Started

After completing the introductory briefing, follow the initial objectives into the main excavation area. Once you pass through the shutters, the gigantic egg descends, marking the beginning of your main assignment.

Each of the four players has a named keycard that grants access to terminals, shops and other laboratory facilities. If you play cooperatively, pay attention to your own keycard and the equipment available to you.

Near the egg, you will find a central terminal that monitors its agitation levels. This is an important part of the gameplay because repeatedly excavating the same area can agitate the specimen and eventually trigger a reaction.

CRACK also uses a shift-based structure. After each shift, you receive time to rest and participate in side activities. Use this downtime to manage your resources and prepare for the next stage of excavation.

1. Break the Egg’s Outer Shell

Your first task is to remove the egg’s outer shell. Pick up the starter pickaxe to break the shell and use the chisel to separate the broken pieces.

Next, visit the Resource Depot and collect buckets from the conveyor belt. Carry them to the excavation area, fill them with shell fragments and deliver the collected material to the conveyor belt.

Every Mk 1 bucket of outer shell earns $9. This is your initial source of income, so focus on collecting and delivering as much material as you can before purchasing expensive equipment.

You can also throw buckets, including full ones, to speed up the delivery process. In cooperative play, each player earns money individually, making it possible for teammates to work toward their own equipment purchases.

Tips for Efficient Shell Excavation

• Keep your buckets moving between the excavation area and the Resource Depot.
• Separate broken shell pieces efficiently with the chisel.
• Avoid spending all your early earnings on optional purchases.
• Check the specimen’s condition while excavating rather than concentrating exclusively on gathering materials.

Your goal at this stage is to build enough funds to purchase the first shovel and begin working on the next layer.

2. Buy the Mk 1 Shovel and Excavate the Membrane

Once you have removed the outer shell, the next layer is the membrane, a greyish material beneath the white exterior. The starter equipment will not be sufficient for every stage of excavation, so you need to purchase a shovel.

Visit the Company Store and purchase the Mk 1 Shovel for $13. Add the tool to your cart and complete the purchase minigame at the terminal.

Return to the egg and use the shovel to excavate the membrane. Collect the resulting fragments in buckets and transport them to the Resource Depot.

Each bucket of membrane earns $15, providing a better return than the outer shell. This increase in income helps you save for subsequent equipment upgrades.

Should You Buy a Vehicle Early?

Vehicles become available relatively early in CRACK, but purchasing one immediately may not be the best use of your money when playing solo. Unlocking vehicles costs $25, which can represent a substantial portion of your early earnings.

If you are playing with four people, the group may be able to afford a vehicle sooner. Otherwise, consider improving your excavation equipment first and purchasing a vehicle once your income becomes more reliable.

Vehicles can later be upgraded to carry more buckets and tools, improving transportation efficiency. The key is to balance immediate convenience against the cost of equipment that helps you excavate deeper.

Remember that tools wear down with repeated strikes. You will need to replace or upgrade them as you progress, so maintaining a reserve of money is important.

3. Unlock the Tissue Layer and Workbot Storage

As you excavate deeper, the game introduces additional materials, including Blight and Calcified Nodules. Follow the objectives that appear and continue upgrading your tools and transport vehicle as necessary.

Eventually, you will move beyond the grey membrane and reach the pink tissue layer. This is an important milestone because tissue unlocks access to the game’s automation systems.

To unlock Workbot Storage, deposit approximately $70 worth of tissue. Once the requirement is met, you can begin investing in machines that automate collection and transportation.

Use Scaffolding to Reach Higher Areas

Excavation is not limited to the areas immediately within reach. You can construct scaffolding around the egg to reach elevated sections and continue removing material.

Build your scaffolding with proper support. Poorly supported structures can collapse, wasting time and potentially interrupting your work. Specimen reactions can also damage scaffolding, making structural stability an important consideration throughout the game.

As you move into more advanced stages, your progress will depend on more than simply having enough money. You must also maintain safe access to the egg and respond to environmental hazards before they interrupt your operation.

4. Automate Resource Collection With Workbots

Workbots are among the most useful upgrades in CRACK because they reduce the amount of manual work required to collect and transport excavated materials. Once the system is unlocked, you can devote more attention to digging, upgrading tools and managing the specimen.

There are two main types of Workbots described in the walkthrough.

Collector Bots

Collector Bots search for empty buckets and fill them with excavated materials. They automate the collection stage, reducing the need to repeatedly move between the egg and individual buckets.

Delivery Drones

Delivery Drones transport filled buckets to the Resource Depot. They handle the delivery stage, helping keep your collection system operating while you focus on excavation.

Both types operate autonomously. You do not need to issue individual commands, and you cannot directly instruct a bot to perform a specific task.

Workbot Prices

Automation requires a significant financial investment, particularly as you purchase additional units. The supplied walkthrough lists the following prices for Collector Bots:

• First Collector Bot: $100.
• Second Collector Bot: $150.
• Third Collector Bot: $200.

The price increases with additional purchases, and Delivery Drones follow the same general pricing pattern. Therefore, you should consider how much manual work your current setup requires before investing in another machine.

One well-timed automation purchase can improve efficiency, but buying too many units before your income can support them may slow your progress toward other upgrades.

5. Repair Workbots and Collect Chalazite for Upgrades

Workbots do not operate indefinitely without maintenance. They can break down during operation, interrupting collection or transportation until they are repaired.

Carry a wrench so you can repair malfunctioning machines. Check your automated operation regularly, because a broken bot can reduce the benefits you receive from investing in automation.

How to Upgrade Workbots

Unlike ordinary equipment, Workbots cannot be upgraded simply by spending money. Their upgrades require Chalazite, a resource that you must locate using the Scanner.

To improve your chances of finding Chalazite, upgrade the Scanner’s scan depth and sensitivity. These improvements help you search for deposits more effectively.

Different colours of Chalazite provide different amounts of upgrade progress, and Workbots can reach a maximum of five upgrade levels.

Important tip: Do not sell Chalazite when you find it. Keep it stored for Workbot upgrades instead. Spending it as an ordinary resource could delay your ability to improve your automated operation.

CRACK Egg Reactions: All Seven Major Hazards

The giant egg is not a passive excavation site. Repeatedly digging in the same area can increase its agitation, and continued agitation can trigger a reaction event. These incidents can disrupt the laboratory, damage structures and force you to stop your regular work.

The supplied walkthrough identifies seven types of reactions.

1. Tentacles

During a tentacle event, the laboratory turns red and multiple tentacles emerge from the egg. The reaction can introduce an immediate hazard to players working nearby.

2. Magnetic Field

The egg generates a magnetic field that attracts loose metallic objects, including tools. The magnetic effect can also break scaffolding, potentially cutting off access to elevated excavation areas.

3. Bugs and Parasites

Various bugs or parasites emerge from the egg. These events add another hazard to the excavation process and can interfere with routine work.

4. Eye Anomaly

A large eye appears on the egg during this reaction. It is one of the unusual specimen events that players may encounter while digging.

5. Tremors

Tremors shake the environment and can break down scaffolding. If you rely on elevated platforms to reach an excavation area, structural damage can interrupt your progress.

6. Flooding

Pressure lines rupture during a flooding event, allowing water to spread through the laboratory. This reaction disrupts the work environment and requires you to respond before returning to your normal tasks.

7. Regeneration

Regeneration is particularly disruptive because the egg restores previously excavated areas. As a result, work that has already been completed may need to be repeated.

How to Control Specimen Agitation

Managing the egg’s condition is essential to maintaining steady progress. If you ignore agitation alerts, a reaction may damage your equipment or undo part of your excavation work.

Use the following precautions:

• Monitor the central terminal: Check the egg’s condition regularly to identify changes in agitation.
• Spread out your excavation: Avoid repeatedly digging the same spot when other areas are available.
• Apply sedatives promptly: When an agitation alert appears, head to the Sedative Application Terminal and complete its minigame successfully.
• Protect excavated areas: Use Support Spokes to prevent excavated sections from regenerating during a reaction.
• Prioritise emergencies: Stop routine work when a reaction begins and focus on neutralising the immediate threat.

To apply a sedative, you must successfully complete the terminal’s minigame. Make this a priority whenever the game instructs you to intervene.

The most important lesson is to treat specimen management as part of your regular work rather than an occasional emergency. A controlled excavation operation is more useful than one that repeatedly loses progress to preventable disruptions.

CRACK Secret Room Guide: How to Find the UV Flashlight

The laboratory contains hidden information that can help you uncover its secrets and pursue the alternate ending. One of the most important discoveries is the UV Flashlight, which allows you to reveal concealed code fragments and investigate areas that are not immediately accessible.

Finding it requires you to unlock Custom Scaffolding and reach a ventilation shaft above the Breakroom.

Step 1: Unlock Custom Scaffolding

Progress through the game’s objectives until Custom Scaffolding becomes available. You will need it to build upward and reach the ventilation shaft.

Step 2: Reach the Ventilation Shaft

Construct scaffolding high enough to access the ventilation area above the Breakroom. Check that the structure is properly supported before climbing, as collapses can interrupt your attempt.

Step 3: Open the Vent Panel

Bring a hammer and use it to strike the screws securing the panel. Once the path is open, enter the ventilation shaft and retrieve the UV Flashlight.

Step 4: Investigate the Dead Crew Member

Do not leave the ventilation shaft immediately after collecting the flashlight. Continue to its end, where you will find a deceased member of one of the previous crews.

Pick up the clipboard nearby. It contains additional information about the facility and contributes to your investigation of the events surrounding the laboratory.

How to Find the Redacted Room Password

With the UV Flashlight in your possession, you can search the laboratory for the code needed to open the Redacted Room.

The password is different for each player, so using another player’s code will not necessarily work. However, the locations of the code fragments remain the same.

Search these three locations in order:

• First two digits: Check the right-side wall of the Breakroom near the slot machines.
• Second two digits: Examine the area near the right-side wall of the Vehicle Bay.
• Final two digits: Look directly above the Redacted Room’s keypad.

Once you have collected all six digits, enter your complete code at the keypad to unlock the room.

The Redacted Room is not required to complete either ending described in the walkthrough. However, it contains important information about the facility, making it worth exploring if you want to understand more of the game’s mystery.

CRACK Endings Guide: How to Unlock Both Endings

CRACK offers two endings that reflect different choices regarding the specimen and the laboratory’s objectives. One ending follows the facility’s instructions and processes the specimen. The other involves uncovering a secret route and escaping with it.

Ending 1: Process the Specimen

The first ending follows the laboratory’s intended procedure. Your objective is to locate the Core Specimen, secure it and deliver it to the designated processing area.

Follow these steps to complete the specimen-processing ending:

• Step 1: Locate the Core Specimen.
• Step 2: Find the Containment Sac inside the egg.
• Step 3: Secure the Core Specimen before moving to the processing stage.
• Step 4: Enter the Processing Chamber.
• Step 5: Insert the specimen into the designated location.
• Step 6: Complete the processing procedure and dispatch the resulting product.

Completing these steps awards the Reach 1/2 Ending tag, as described in the supplied walkthrough.

This route is the direct option for players who want to finish the facility’s assigned task. It focuses on completing the objective rather than investigating an alternative way out.

Ending 2: Escape Through the Secret Exit

The second ending requires more exploration. Instead of following the laboratory’s demands, you must investigate the hidden messages and uncover a concealed escape route that allows you to leave with the specimen.

Step 1: Find the Hidden Messages

Search the ventilation shaft and the Redacted Room for messages that reveal information about the secret exit. This is why obtaining the UV Flashlight and unlocking the restricted room are useful parts of the investigation.

Step 2: Break Through the Blocked Exit

Use the hammer to break down the boards blocking the exit. Enter the room beyond the obstruction and look for the clipboard on the ground.

Read the clipboard to learn about a passage that has been blocked by dirt.

Step 3: Uncover the Hidden Stairs

Use your tools to remove the dirt blocking the passage. Continue digging until you uncover the stairs leading upward.

Step 4: Bring the Specimen to the Locked Door

Continue through the newly uncovered route until you reach the upper section. There, you will find a locked door that opens only when the specimen is present.

Secure the specimen and carry it to the door. Once the specimen is brought to the required location, the door opens and you can complete the secret escape ending.

This route rewards players who take the time to investigate the laboratory rather than concentrating exclusively on the main excavation objectives.
