In the early game, aim for Amethyst Components, Amethyst Part, and Buck Capsules as they will reinforce your foothold in Valley IV for when you unlock Ferrium in the mid to endgame.

Amethyst Component will be used for early game gear crafting to get basic armor skills for your Operators, while Buck Capsule C are used for Stock Bill Trading.

Viable Until You Unlock Ferrium

The early-game spans from the start of the game until you are able to mineFerrium at around Authority Level 18. Be sure to evolve together with your factory to get stronger items and gear!

Best Early Game Layouts

Amethyst Component Layout

Amethyst Component for Gears Blueprint

First of all, you'd want to aim for the creation of Amethyst Components, which will allow you to craft early game gear for exploration. This allows you to take on up to level 30 enemies in the Quarry areas.

The buildings needed here are unlocked via the main quest so it is not missable. You will be required to create the Amethyst Component.

Buck Capsule C Layout

Create Buckflower Powder Loop Farm

Infinite Seed-Planter Loop Blueprint

To start the Buck Capsule C factory, you'd want to create a self-loop infinite Buckflower Powder Factory which allows you to create a self-sustaining plant farm. You may then pass the output into a Shredding Unit to create Buckflower Powder.

The Buckflower Powder will be plentiful, and you can even use the excess for general healing.

Combine With Amethyst Bottle in Filling Unit

Buck Capsule C Blueprint

To take it even further, connect the output of the Buckflower Powder Farm into another input of the Filling Unit in the Amethyst Bottle production line to finally create the Buck Capsule C. This item can be sold in the Valley IV outposts for Stock Bills!

Automate Amethyst Parts

Amethyst Part Blueprint

If you have extra Amethyst, consider creating Amethyst Parts to start storing this material for later use. Lots of buildings and machines also use Amethyst Part, so consider stocking up.

Early Game Tips

Take Over Mining Nodes

Mineral Bed

Mining Nodes are your source of raw materials like Originium and Amethyst, so try to take over as much mining nodes as you can in the field. They are called Mineral Beds and are marked in your map with a rock icon.

They are scattered around the map and will have varying purities, so exploration and story progression is a must. In addition, rushing to get the Electric Mining Drill is a necessity since the machine automatically teleports the materials to your PAC Hub.

What is Mining Purity and How to Increase It

Use Originium on Thermal Banks

Towards the end of endgame, you may see your factory lacking in power. On that note, it is essential to unlock the Thermal Bank and feed it fuel to add power to your grid.

It may be tempting to use Batteries for this, but we strongly recommend using Originium first. Producing batteries will eat up amethyst, which is a scarce in the early game.

Thermal Bank Recipes and How to Use

Do Not Overuse Amethyst!

Amethyst is going to be the bottleneck of your builds in the early game so it is important to choose which produce to make. On that note, the items above is enough to take you to the mid-game where you'll unlock the Ferrium Ore production.
