A Guide to Milestones and Tiers in Satisfactory

In Satisfactory, players unlock new technologies and advancements through Milestones, organized into Tiers. Each tier presents progressively more advanced unlocks that require specific resources to progress. Here’s a breakdown of the major Tiers, what they unlock, and what you need to unlock them.

Tier 1 and 2: Basic Infrastructure and Automation
The first two tiers focus on setting up basic infrastructure for your factory.

Key Unlocks:

• Logistics: Conveyor belts, splitters, and mergers for efficient resource transportation.
• Power Infrastructure: Biomass burners for energy production.
• Storage: Personal storage boxes and larger storage containers for managing resources.
  What You Need to Unlock:
• Iron Plates
• Iron Rods
• Concrete
• Wire
  Most of these resources can be manually crafted early in the game using the Hub and Crafting Bench. As you automate production, gathering these resources for milestones becomes easier.

Tier 3 and 4: Advanced Automation and Power
Tiers 3 and 4 introduce more complex systems and unlocks necessary for scaling your factory.

Key Unlocks:

• Coal Power: A more sustainable power source than biomass, allowing longer and more efficient factory runs.
• Assembler: A machine that enables the crafting of more complex components like reinforced plates and rotors.
• Tractor and Truck Station: Automate resource transport between distant areas.
  What You Need to Unlock:
• Reinforced Iron Plates
• Rotors
• Modular Frames
• Concrete
  These resources require more advanced setups, with machines like the Assembler to combine raw resources into higher-level components.

Tier 5 and 6: Oil, Advanced Materials, and Logistics
Tiers 5 and 6 bring massive factory expansions and introduce oil-based products, which play a crucial role in more advanced technologies.

Key Unlocks:

• Oil Processing: Enables the extraction and refining of oil into plastics and rubber.
• Trains: Unlocks rail-based transport, ideal for moving large quantities of materials across vast distances.
• Manufacturer: A multi-input machine required for assembling high-end products.
  What You Need to Unlock:
• Motors
• Heavy Modular Frames
• Steel Beams
• Steel Pipes
  Oil-based resources are critical here, so setting up oil extraction and processing will be key for progressing through these tiers.

Tier 7 and 8: Endgame and Nuclear Power
In the final tiers, players unlock advanced energy solutions and components critical to reaching the endgame.

Key Unlocks:

• Nuclear Power: The most efficient but dangerous energy source, requiring careful management of uranium.
• Jetpack and Gas Mask: Mobility and survival tools for navigating hazardous environments.
• Programmable Splitters: Enhances logistics and resource management efficiency.
  What You Need to Unlock:
• Supercomputers
• Uranium
• Aluminum Sheets
• Advanced AI Components
  These tiers require complex automation systems and significant factory expansions, with high-end resources only available through advanced machinery and logistics.

The Milestones and Tiers in Satisfactory represent a progression system that rewards strategic planning and factory expansion. As you progress, resource requirements become more complex, encouraging you to automate your production lines and scale up your factory operations. Proper planning, resource management, and efficient use of machinery will allow you to unlock the highest tiers and dominate the world of Satisfactory.
