How to Reach Milestone 4 in Lightyear Frontier
Reach Milestone 4 through colony deliveries, identify missing ingredients and avoid following an outdated unlock checklist.
Milestone 4 is a delivery goal
Advance the colony delivery progression to reach Milestone 4. In 1.0, this is also where automation begins to enter the unlock sequence. You do not reach it by constructing four buildings, raising a combat level, or spending a separate set of skill points.
The useful question is which available delivery you can complete with your present tools and recipes. Old milestone charts can point to the wrong unlock order, so use the requirements displayed in your own world.
Work backward from one shipment
Open the Delivery Cannon and choose an order. Separate its requirements into three groups: goods already stored, goods you can produce now, and goods whose recipe or ingredient you have not discovered. Start with an order whose final group is empty or easy to resolve.
- Reserve the materials needed to operate your farm and finish the order's processing chain.
- Plant only the crop quantity you can maintain, adding a practical surplus for seeds and future production.
- While it grows, gather the non-crop requirements and prepare any intermediate components.
- Recheck the full order before submitting. One missing component can keep the shipment unavailable.
- Send the delivery, inspect the progression screen, and repeat until the milestone advances.
Do not spend your entire stock on decorative construction while a single missing part is blocking the next useful unlock. Equally, avoid turning every seed into a delivery: restarting a crop supply is work that does not move the milestone forward.
Diagnose a stalled delivery
| What you see | Next action |
|---|---|
| Enough raw material, but shipment still unavailable | Compare the requested processed item with what you own |
| One ingredient remains undiscovered | Explore or inspect the recipe chain before expanding fields |
| An order asks for equipment beyond your current recipes | Choose another available route and review progression |
| A recipe appears to unlock incorrectly | Update the game and check again; the first 1.0 hotfix addressed recipe ordering |
What to build after unlocking it
Start automation with one small, useful connection rather than redesigning the whole farm. Choose a component you repeatedly craft, give it a clear input supply, and confirm it produces the expected item before adding branches. Earlier automation does not mean every late-game machine becomes available at Milestone 4.
Read the automation crafting guide for a first production line. If ordinary farming is the bottleneck, improve crop rotation before multiplying your field area.
