Your mission: to protect Earth
Real-time Threat System
Asteroids, comets, and interstellar objects are discovered suddenly and can pose a threat to our planet.
Real celestial mechanics
All objects in the game move according to the real-world laws of Newtonian celestial mechanics, and behind the scenes, the system performs actual calculations of rendezvous parameters, just like in real interplanetary missions. And you can control it all with just one finger!

Entertain while Teaching
The game shows the basic principles of spaceflight in elliptical orbits—there is no straight-line motion in space.
The Earth is under threat
As the game advances, there will be more and more dangerous objects, and you'll need to refine your tactics and strategy to defend the planet and earn more points.
Global cross-platform leaderboard
Rival other asteroid and comet hunters from around the world and rise to the top of the leaderboard!

Atmospheric visuals
A dynamic starry background, various types of orbits, and smooth animations of celestial objects that draw you into the game from the first seconds.
What's new?
Version 1.0.3 has been released
The key word for this update — smoothness.
- A major, long-hidden recurring bug that caused the aim path to “jitter” has been detected and expelled.
- Smooth scrolling of the global player leaderboard has been added, with a frame rate of up to 120 Hz (if your phone supports it). Now you can see where you stand compared to other hunters.
- Smooth control — fixed slight jumps of game screen that occur when touching the screen with two fingers to move the camera or when canceling aiming.
- Computational performance has been optimized for even smoother gameplay, and a few other tweaks have been made under the hood.
