Star Birds takes you on an impressive journey through the asteroids, where you have to mine resources and deal with the secrets these asteroids hold as our bird friends fare the space near their home planet.

In Sector 3, you’re asked to produce Mirror and Laser, and crafting them isn’t easy because you’ll have to set up different types of resource production until you get there.

Introduction

At the start of Sector 3, you’re greeted with a small cutscene that discusses the origins of the strange object that you discovered in the previous sector. The crewmates suggest referring to the mysterious object as a Strangelet.

After that, the crewmates discuss the possibility of going to another star system. But for that, they’ll need more resources from here so their friends can fix up the starship, and you can go to another star system.

The view will shift to the map, where you can see three discovered asteroids, alongside three that are yet to be discovered. You’ll immediately receive a request from the captain, asking you to gather one Laser and 10 Mirrors and send them to the spaceship. Completing this quest will result in the completion of Sector 3.

Figuring Out The Required Resources

Both of these materials are something you’ve yet to produce. For that, you’ll have to click on the quest icon and then click on each material to see how to craft them.

For Laser, you’ll have to combine Uranium and Glass in an optics factory. Luckily, there will be an asteroid with Uranium discovered. But you’ll still have to make preparations for the rest.

To craft Mirror, you’ll have to combine Light Alloy and Glass in an optics factory. It is clear now that optics factory and Glass will play a major role in this sector.

If we break it down further, Glass can be refined from Quartz with the help of a refiner. And, for Light Alloy, you’ll have to combine Aluminium and Silicon in a crucible.

Landing In The Unknown

The game doesn’t specify any asteroid that you have to land on, but picking the one with Uranium on it is recommended since it’s the only resource we’re familiar with right now that is required to produce some of the items. As you land on the asteroid, you’ll discover Uranium and Magnesium reserves on it.

Start by setting up a few extractors on Uranium and accept some modules to start earning credits and raise your Station level.

Now, set up another launch pad. Set up four extractors on Magnesium and connect them to the second launch pad. Now, you’ll have a steady supply of both Magnesium and Uranium.

Check the modules, and you’ll find that you can complete the Lab due to the new Magnesium supply. Accept the module and complete it to raise your Station level.

Setting Up A Crucible

Now that we have a steady supply of two materials, it’s time we start working on our main objectives. Start researching the crucible, but you’ll need Silicon and Aluminium to complete the research.

Head back to the map, it’s time to look for Silicon and Aluminium. Check if any of the other asteroids have at least one of the resources we’re looking for.

Enter the other asteroid with Silicon and place a launch pad on it. You’ll also find Sulfur here, but we don’t really need it right now. Set up extractors on the Silicon and connect them to the launch pad.

Head back to the map and now look for an asteroid that has Aluminium on it. Land on it and set up a launch pad on the Aluminium asteroid. Complete modules or deploy a rover to get the necessary Credits if you run out of them.

You’d have enough resources to complete the research on the crucible now. Complete the quest once all the resources have been delivered.

Discovering An Energy Source For The Crucible

As you know, Light Alloy can be produced at a crucible by combining Aluminium and Silicon. Place the Crucible on the Aluminium asteroid. You’ll need to place this structure on a small crater.

You’ll need energy to power up the crucible, and figuring out how to generate energy will be the next challenge.

To produce energy, you’ll have to set up solar panels. However, for researching solar panels, you’ll require Glass. We’ll have to halt our crucible and production for now and focus on producing Glass.

Setting Up Glass Production

Head back to the map and look for an asteroid that has either Water or Silicon on it, because combining the two in a chemical lab will produce Quartz, which is required to produce Glass.

Head to the other asteroid that has Water on it and set up a launch pad there. Set up extractors on Water and connect them to the launch pad. Now, on the same asteroid that has water on it, build a landing pad.

We’ll have to bring Silicon over here, so we can start producing Quartz. Head back to the map, and drag the Silicon transport line from the Silicon asteroid to the Water asteroid.

Now, head back to the Water asteroid and set up a chemical lab near the landing pad and connect it with the landing pad, and an extractor on Water. This process should receive Silicon from the landing pad, send it to the chemical lab, where it will be combined with Water coming from an extractor to produce Quartz.

For the final step, you need to build a refiner. Place the refiner near the chemical lab, and have the Quartz delivered to it, and then connect the refiner to a launch pad to send the produced Glass to the spaceship.

If you’ve done it right, the Glass production should be going smoothly, and your research for solar panels will be completed shortly.

Powering Up The Crucible

Now that we have Glass to produce solar panels, go back to the Aluminium asteroid where you had built the crucible. Place at least three solar panels, but be wary that you can only put solar panels on the side of the asteroid that’s facing the sun.

Connect these solar panels to the crucible. Both Aluminium and Silicon are required to produce Light Alloy. You’ll have to set up a landing pad to receive Silicon from the other asteroid.

However, we’re already sending Silicon to the Glass production asteroid. Head to the Silicon asteroid and set up another launch pad, and connect it to several extractors. Reroute the newly crafted launch pad’s route to the asteroid with Aluminium. This way, we can produce Glass and Light Alloys with Silicon without interruptions.

Head back to the Aluminium asteroid and build another launch pad, and connect the crucible to it. We’re doing this because we need the Light Alloy on another asteroid.

Setting Up An Optics Factory

After we’ve gotten all the base resources, we need to build an optics factory. Head to the Water asteroid and start researching it there because we’ll be needing Glass, and we’re already producing it there. Wait for the research to complete.

After you’ve built an optics factory, you’ll get another tutorial message, and this time you’ll be asked to build a pipe hub so you can transfer resources to two places from the same refiner.

Researching The Pipe Hub

To start the research, you’ll need Iron, and that’s not something we’ve set up production for in this sector. Accept the research and head back to the map.

Look for an asteroid that has Iron on it and set up a launch pad there. We could also use the asteroid that we had been previously working on to gather Water, as it also had iron, but it’s better not to fill it with too much clutter. You should be able to gather the required Iron quickly. And once that’s done, head back to the Water asteroid to set up the pipe hub.

Producing Laser And Mirrors

We’re in the endgame now for this Sector. Everything is ready, and we just need to connect the dots. You’ll need to set up a landing pad to receive the production from other asteroids.

First, we should focus on crafting Laser. Connect the Uranium transport line to the newly crafted landing pad on the Water asteroid and then link it to the optics factory. Set up a launch pad as well to send the resources back to the space station.

Note that the optics factory also needs some energy, so you’ll have to craft at least three solar panels and place them in the sunlight.

Now that you have produced the Laser, half our work is done. You need to craft mirrors next, and that would be easy as well.

Head back to the map and remove the Uranium transport line from the landing pad connected to the optics factory. Replace it with Light Alloy and watch it work.

Wait for the production to begin, and once you’ve sent out 10 units of Mirror, you’ll be able to complete the quest and end Sector 3.

Ending Sequence

After completing Sector 3, our bird friends will finally embark on their journey into deep space. Now that they’ve gathered all the resources they needed, there’s nothing to fear.

It takes them a whopping 96 years to reach their destination in deep space, and as our bird friends wake up from their sleep, we’ll see what secrets await them in the next Sector.
