ESA SHIELD - Earth's Safety Starts with You!

Join the European Space Agency's SHIELD mission and discover why aliens aren't the biggest threat to us! In this science-based Planetary Protection Simulator, you fight real cosmic hazards. Build, Monitor, Protect! Become Earth's Last Defense.

Become head of the European Space Agency's Space Safety Department and protect Earth from real cosmic hazards like Asteroids, Space Debris, and Space Weather. This science-based Planetary Protection Simulator combines tower defense, roguelite, and strategy elements to create a unique gameplay experience grounded in reality.

☄️ Encounter Real Space Threats: Face the same dangers ESA deals with today. Coronal mass ejections, asteroid impacts, and space debris. Each threat behaves differently, affecting systems in unique ways, and demands its own monitoring and defense approach. Every decision could be the difference between survival and orbital disaster.

🔬 Research Real Technologies: Unlock and implement real-world tech from past missions, current prototypes, and near-future plans. Build your strategy using actual science and engineering: from telescopes to deflection rockets.

🛰️ Build and Customize Satellites: Design your own space systems: choose components, mission goals, and orbital paths. Balance cost, stability, and lifetime to create your optimal satellite system.

📡 Monitor the Skies: Deploy and upgrade detection systems like telescopes and radar arrays. Expand your coverage, improve precision, and catch incoming threats before they hit.

🚀 Defend Earth and Infrastructure: Build and operate space-based defense systems to prevent catastrophic impacts. Launch interceptors, trigger system shutdowns, or send clean-up bots into decaying orbits.

🎯 Make Strategic Decisions Under Pressure: Every threat comes with uncertainty. React with limited data, weigh the risks, and choose between bold moves or conservative actions. Your judgment matters.

Under a programme of, and funded by, the European Space Agency.
