Milestones

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 resources. Sets of milestones are grouped together into tiers, and all but tier 0 are locked to the engineer from the start of the game. Completing tier 0 unlocks tiers 1 and 2, and completing phases of the Space Elevator unlocks tiers after that.

Note: The below milestones are not necessary ordered as you will see in your session. The ordering of milestones within the same tier is dependent on the sequence of your M.A.M research.

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

Tips

 * Later milestones have longer cooldown. For example, jetpack and gas mask milestones at tier 6, you could fulfill all jetpack material, without pressing the launch button, select the gas mask milestone and fulfill it. Then you could launch jetpack milestone immediately followed by gas mask milestone. This way you could save a lot of time.
