About Dirty Business
Dirty Business is an early‑access simulation where players construct and expand a hidden criminal complex beneath a city. The game focuses on producing illegal goods—drugs, weapons, counterfeit money—and managing the logistics needed to sell them.
Players can operate alone or join up to four friends in online co‑op, hiring workers, upgrading facilities, and controlling distribution channels ranging from elevators to a secret cartel airstrip. The experience includes full controller support, adjustable difficulty, and the ability to save at any time.
01 / THE GUIDE
Underground Base Expansion
The core of the game is building an underground base that can be expanded and upgraded over time. New rooms can be unlocked, and an underground garage can be added to support a larger distribution fleet.
Base upgrades allow players to increase production capacity and unlock side production rooms, giving more options for illegal manufacturing and storage.
- Prioritize garage upgrades early to improve shipment flexibility.
- Balance expansion with crew hiring to avoid idle facilities.

Illegal Production
Players can produce multiple drugs, counterfeit various currencies, and manufacture weapons. Production rooms specialize in different illegal items, and workers are assigned to grow plants, synthesize chemicals, or assemble arms.
Orders can be completed for customers or sold directly for maximum profit, giving players strategic choices on how to monetize their output.
- Focus on high‑profit items first to fund base upgrades.
- Use a mix of production types to diversify income streams.

Distribution Channels
Small and medium shipments are sent to the surface via elevator, while larger loads use front‑company vehicles. Massive orders are dispatched from a secret cartel airstrip to distant city areas or across the country.
Players may handle distribution personally or hire street dealers to move products, allowing flexibility in managing risk and efficiency.
- Use the airstrip for high‑volume orders to reduce surface exposure.
- Hire dealers for routine city deliveries to free up time for expansion.

Crew Hiring and Growth
Workers are hired to operate production rooms, grow plants, and assemble weapons. Street dealers can be recruited to handle sales across the city, extending the reach of the criminal network.
A larger crew enables faster production cycles and more efficient distribution, directly influencing profit margins.
- Balance production staff with dealers to keep supply and demand aligned.
- Upgrade crew facilities to improve worker efficiency.

Solo and Co‑op Modes
Dirty Business supports single‑player and online co‑op for up to four friends. In co‑op, players collaborate to build and grow the criminal empire together, sharing responsibilities for production and distribution.
Both modes retain full controller support, adjustable difficulty, and the ability to save anytime, ensuring a consistent experience regardless of play style.
- Assign each player a specific role (production, logistics, upgrades) for smoother teamwork.
- Communicate shipment schedules to avoid bottlenecks.
