Milestones

"To achieve company milestones according to satisfaction we expect you to construct your FICSIT Inc. factory in such a way that it allows for easy expansion and complexion. Not only will buildings grow more complex over time, so will the parts they produce. Project Assembly isn’t your average high-school science project. We’re making history here! Go big or go home! Of course, this requires both high-level and low-level power management, good luck getting to nuclear!"

- Caterina Parks's assistant Steve

Milestones are the primary method of progression in the game, allowing the engineer to unlock new buildings, recipes, equipment, and more. They can be completed at the HUB Terminal by inputting the specified resources. To do so, move near the terminal (the PC-shaped booth inside the HUB), interact with it, then + the required material in your inventory.

Sets of milestones are grouped into tiers. At the start of a new game session, only Tier 0 is available (unless Onboarding is skipped, which will skip Tier 0 as well). Completing Tier 0 unlocks Tiers 1 and 2, and completing phases of the Space Elevator unlocks higher tiers.

Parts inserted into the HUB Terminal cannot be taken back.

Tier 0
Tier 0 focuses on upgrading the HUB. Unlike milestones in later tiers, these must be completed in sequential order. Each milestone changes the HUB's appearance as well.


 * Note: The two Biomass Burners that are added to the HUB are smaller than the standalone version, each only produces 20 MW instead of 30 MW. They also burn fuel proportionally slower.

Tier 1
Requirements: All Milestones from Tier 0 completed (The HUB is completed) or Onboarding is skipped

Tier 2

Tier 3
Requirements: Space Elevator Phase 1 completed

Tier 4
Requirements: Space Elevator Phase 1 completed

Tier 5
Requirements: Space Elevator Phase 2 completed

Tier 6
Requirements: Space Elevator Phase 2 completed

Tier 7
Requirements: Space Elevator Phase 3 completed

Tier 8
Upcoming Requirements: Space Elevator Phase 3 completed

Important note: In an official video by Coffee Stain, it was confirmed that information previously listed in this section came from very old builds of the game, and was implemented as a prototype. To avoid misinformation, it was removed.
