How to Play

As you take your place in the cockpit of your mothership, you'll be armed with the WASD keys to navigate your spaceport through the cosmos. To move your cursor across the screen and select building sites, simply hold the arrow key. To make precise movements, you can toggle the cursor movement option from the settings menu.

Defend Your Empire

The core of your mission is to protect your mothership from the relentless waves of alien probes. These explosive intruders emerge from quantum portals, aiming to sabotage your defenses. To stop them, you must strategically place and upgrade your structures, including turrets, shields, and repair drones.

Build and Prosper

As you repel attacks, you'll need to manage your resources wisely. This means balancing your spending on construction, upgrades, and maintenance. Keep your energy levels high, your walls strong, and your fleet ready for battle. The key to victory lies in your ability to foresee the enemy's next move and fortify your defenses accordingly.

Resources and Structures

To ensure your empire prospers, you must carefully manage your resources. Gather minerals, energy, and other valuable goods from asteroids and space debris to fund your defenses. With these materials, you can construct and enhance various structures, each with its own unique capabilities.

The Challenges Ahead

The alien invaders are relentless. The more time you spend defending your mothership, the more intense the attacks will become. Each wave is harder than the last, pushing your strategy and resources to their limits. Can you hold the line against the encroaching darkness?

Ready for Launch

Space Builder Defender is more than just a game—it's a challenge to your ingenuity and resilience. Will you rise to the occasion and secure humanity's future among the stars? With Space Builder Defender, the galaxy is your canvas, and the enemy is your canvas. Let the construction begin!
