First steps when you load in

Step

In short Redeeming codes the moment you start is the fastest way to get a head start on buildings and resources.

Before you place a single building, open the settings panel and redeem any available codes. Codes hand you free buildings like the Research Lab and Industrial Drill. Once your free buildings are placed, keep your resource and manufacturing lines running without stopping.

Open settings click the Settings icon on the left side of the screen to find the code entry box.
Enter your codes type each code into the 'Insert Codes Here' box and press Enter to claim your free buildings.
Place claimed buildings deploy the Research Lab and Industrial Drill right away so they start contributing immediately.
Start your production line keep resource refining and item manufacturing running continuously from the beginning.
Train soldiers begin training troops so you have units ready for combat.
Plan your power add or upgrade power generators before you run out, because each new building increases your base's energy demand.

Unit controls

Check

In short Mastering drag-selection and the queue command lets you move groups of units during both attacks and base defence.

All unit commands use your mouse and keyboard together. You can control a single unit or manage an entire army depending on which combination you use. The queue command is useful when you want units to carry out several actions in sequence.

LMB selects one unit at a time.
Shift + LMB adds another unit to your current selection.
LMB + Drag selects every unit inside the box you draw.
Shift + LMB + Drag adds multiple units to an existing selection.
Ctrl + LMB moves your selected units to the clicked position.
Ctrl + Shift + LMB queues a command so units execute it after finishing their current order.

What each building does

Table

In short Each building fills a distinct role, so placing the right mix early keeps your economy, research, and combat strength growing together.

Your base is only as strong as the buildings running inside it. Some produce resources, some accelerate research, and others generate the powerful units you need for combat.

Research Lab	speeds up technology development and is available free through codes.
Industrial Drill	mines resources to keep your production line supplied.
Vehicle Depot	a legendary building that produces powerful combat vehicles; placement position matters.
Experimental Gantry	used to develop advanced weapons and high-tier units.
Logistics Warehouse	manages the flow of resources across your base.
