Milestones Guide & Unlock Order

Track Lightyear Frontier milestones, prioritize deliveries, and plan unlocks for tools, buildings, automation, and solar energy.

Why Lightyear Frontier Milestones Matter

Lightyear Frontier milestones are the main progression goals for everything you build, craft, and automate. If your farm feels stuck, the fastest fix is usually to finish a delivery and claim the next milestone unlock. This guide breaks down the Lightyear Frontier milestones progression, shows which unlocks matter most, and explains how to prepare deliveries without wasting resources.

Milestones are tied to deliveries. You complete the required packages, claim the milestone, and gain new recipes, buildings, upgrades, or tools. The early steps are short: Milestone 1: Mech Tools needs 1 delivery and unlocks 6 entries, while Milestone 2: Resource Refinement needs 3 deliveries and unlocks 11. Those numbers make the first two milestones excellent momentum builders.

Milestone Map: What Each Theme Delivers

The documented milestone themes cover several production stages. Use this map to plan around the unlocks you need, not just the next package on the delivery list. Exact delivery items and quantities should always be checked in-game before you commit rare resources.

Milestone	Theme	Delivery requirement	Unlock count	Example unlocks
Milestone 1	Mech Tools	1	6	Mech Depot; Spike Saw Sweeping Strike
Milestone 2	Resource Refinement	3	11	Sawmill; Mineral Crusher; Grinder; Trash Compactor
Milestone 4	Bronze Technology & Commerce	Not listed	Not listed	Furnace; Merchant Landing
Milestone 5	Energy	Not listed	Not listed	Combustion Generator; Seed Extractor II
Milestone 6	Trailers & Trailblazer	Not listed	Not listed	Fabricator; Weather Station
Milestone 7	Iron Technology & Neighbors	Not listed	Not listed	Outpost; Compost Box; Loom; Silo; Small Animal Bed; Animal Accessory Studio; Grinder II; Thruster Boost Lv. 2; Tool Range Lv. 2; Field Harvester Mk. 2
Milestone 8	Drones & Roads	Not listed	Not listed	Watering Drone Station; Combustion Generator II; Color Mixer; road pieces; Lock-on Targets Lv. 2; Trailblazer Boost Charges Lv. 1
Milestone 9	Automation	Not listed	Not listed	Automator; Mineral Extractor; Furnace II; concrete and metal building pieces; Water Surfing Lv. 1; Water Efficiency Lv. 2; FM-04 mech parts; Farm Amount Upgrade 2
Milestone 10	Steel Technology	Not listed	Not listed	Oil Mixer; Storage Shed; Seed Extractor III; Combustion Generator III; Steel Frame; Steel Parts; Steel Electronics; Storage Trailer II; Irrigation Hose Mk. 5; Resource Vacuum Mk. 5
Milestone 11	Advancements	Not listed	Not listed	Watering Drone Station II; Silo II; Lock-on Targets Lv. 3; Tool Range Lv. 3; Fertilizer Spreader Mk. 2; Power Armor parts; Farm Area Size Upgrade
Milestone 12	Solar Energy	Not listed	Not listed	Solar Generator; Automator II; Farm Amount Upgrade

The map shows why you should not treat every milestone the same. Milestone 1 is a quick proof of concept: one delivery opens the Mech Depot and Spike Saw Sweeping Strike. Milestone 2 is a production jump with the Sawmill, Mineral Crusher, Grinder, and Trash Compactor. Later themes widen the scope: Iron Technology & Neighbors adds Outpost, Silo, animal furniture, fertilizers, and mech upgrades; Drones & Roads adds the Watering Drone Station and road pieces; Automation adds the Automator, Mineral Extractor, Furnace II, and construction parts; Solar Energy adds the Solar Generator and Automator II.

Build a Delivery Stockpile Before You Commit

A common Lightyear Frontier milestones stall is a resource stall, not a skill check. Deliveries can ask for refined goods, mutated crops, or large crop quantities, so sending whatever happens to be in storage can empty the exact stock you need for the next unlock. Check the target first, then decide whether the delivery is worth finishing now or after the next harvest.

Examples matter here. A delivery can call for a Steel Frame or mutated wheat, and crop pushes can be large enough to ask for 5,000 Polyberry. Karut and chrome maze deliveries are easier to slot into a normal farm cycle, while mutated crops are better saved until your normal targets are done because they compete with seed production.

Resource or item	Why keep a reserve	Milestone context
Iron ore and iron bars	Used in mech upgrades and steel production; iron deposits respawn in valleys	Iron Technology & Neighbors; Steel Technology
Steel Frame, Steel Parts, Steel Electronics	Refined steel goods appear in late delivery requests and advanced construction	Steel Technology
Karut and chrome maze	Crop bundles are repeatable farm output and can be planted around other goals	Delivery examples include these crops
Polyberry	Some requests are large; one target can reach 5,000	Stockpile before committing
Mutated wheat and other mutated crops	Needed for specific delivery packages but compete with normal seed production	Save for last when normal targets are done
Rope, cloth, pillow fluff	Material recipes appear in Iron Technology & Neighbors	Useful for animal and furniture builds
Coal and generator fuel	Powers combustion generators and keeps drones and watering running	Energy; Drones & Roads; Steel Technology

Best Unlock Priorities for a Smoother Run

There is no single official order for Lightyear Frontier milestones, so pick the unlock that removes your current bottleneck. A player who is constantly watering by hand gets more value from Drones & Roads than from a cosmetic paint recipe. A player who keeps filling storage should chase Silos, Storage Sheds, and higher-tier processing.

If this is your bottleneck	Prioritize	Why it helps
Hand-watering and crop upkeep	Milestone 8: Watering Drone Station; Milestone 11: Watering Drone Station II	Automates watering and frees time for deliveries
Full storage and slow refining	Milestone 2: Sawmill, Mineral Crusher, Grinder; Milestone 7: Silo and Grinder II; Milestone 10: Storage Shed	Adds processing and storage capacity
Mech travel and tool reach	Milestone 7: Thruster Boost Lv. 2 and Tool Range Lv. 2; Milestone 8: Lock-on Targets Lv. 2 and Trailblazer Boost Charges Lv. 1; Milestone 11: Tool Range Lv. 3 and Lock-on Targets Lv. 3	Improves harvesting and exploration comfort
Manual crafting and harvesting	Milestone 9: Automator and Mineral Extractor; Milestone 12: Automator II	Adds automation and resource extraction
Power shortages	Milestone 5: Combustion Generator; Milestone 10: Combustion Generator III; Milestone 12: Solar Generator	Adds generation tiers and solar power
Base building and roads	Milestone 4: Merchant Landing; Milestone 8: roads and paints; Milestone 9: concrete and metal pieces	Expands base layout and decoration options

If you are early in a save, finish Milestone 1 and Milestone 2 first. Six unlocks for one delivery and eleven unlocks for three deliveries are strong returns.
Do not rush mutated crop deliveries. Use normal fields for Karut, chrome maze, and Polyberry first, then switch spare capacity to mutations.
Build each new production unlock as soon as you claim it. A Sawmill or Mineral Crusher sitting in the build menu does not help the next delivery.

Step-by-Step: Clear Lightyear Frontier Milestones Without Waste

Use a simple audit before every delivery push. The goal is to avoid submitting a scarce item that blocks a different unlock.

Step	Action	Checkpoint
1	Read the current delivery target and note exact items and quantities	Know whether the request needs mutated crops, steel goods, or a large crop bundle
2	Clear the cheapest useful package first	Early milestones reward momentum; Milestone 1 needs 1 delivery and Milestone 2 needs 3
3	Reserve one stack of iron ore and iron bars	Iron feeds steel production, mech upgrades, and multiple later themes
4	Plant delivery crops before you leave the farm	Crops advance over time, so queue long jobs before exploration
5	Send the package only after the next unlock is within reach	Prevents emptying storage for a milestone you cannot claim yet
6	Build the new unlock immediately and test it	A Watering Drone Station, Silo, or Automator changes your routine only when placed

One more habit pays off: check drone water and fuel before a long trip. If your Watering Drone Station runs dry while you are chasing iron or eggs, the fields stall and the next delivery slips.

Common Lightyear Frontier Milestones Bottlenecks and Fixes

When progress slows, diagnose the bottleneck instead of grinding blindly. Most fixes come back to resource routing, power, or crop timing.

Symptom	Likely cause	Fix
Delivery asks for mutated crops and stalls	Mutated seeds compete with normal crop production	Finish normal crop targets first; dedicate spare field space to mutations
Iron runs dry	Iron is consumed by bars, steel, and mech upgrades	Revisit valleys and mine respawning deposits; keep a dedicated iron reserve
Crops are not ready when needed	Different crops have different growth times; queues are not instant	Plant the longest jobs first and harvest before starting another delivery
Drones stop watering	Water or fuel ran out	Refill the Watering Drone Station and top off generator fuel before leaving
No useful deliveries remain	Current available milestone unlocks are finished	Claim what you have, stockpile iron and crops, and wait for the next unlock or update

FAQ: Lightyear Frontier Milestones

How do you unlock Lightyear Frontier milestones?

Complete delivery packages tied to the milestone, then claim the reward. Milestone 1: Mech Tools requires 1 delivery and opens 6 unlocks; Milestone 2: Resource Refinement requires 3 deliveries and opens 11.

What should I unlock first?

Start with Mech Tools and Resource Refinement because they improve tools and refining. After that, choose by bottleneck: Watering Drone Station for hand-watering, Silo or Storage Shed for storage, and Combustion Generator or Solar Generator for power.

Are mutated crops required for milestones?

Some delivery requests use mutated crops such as mutated wheat. They are not worth dumping early because they compete with normal seed production. Save them for the specific package that needs them.

What if I finish all available Lightyear Frontier milestones?

Claim the final available unlock, then stockpile iron, steel goods, and crops. More milestones may open later, so keeping reserves ready is more useful than submitting packages with no current reward.
