About Project Earth

Blast off on an epic sci-fi journey with Project Earth, a ground-breaking indie action game where your mission is nothing short of saving mankind. Set deep in a hazardous future, your sun is dying, and Earth itself is your spaceship. The stakes are cosmic: master the controls to turn an entire planet into humanity’s only hope for survival. Carefully maneuver Earth through the dying solar system, steering, propelling, and braking to avoid obstacles and harness momentum, all while balancing delicate planetary systems in your quest to escape annihilation.

Project Earth is a visually striking HTML5 browser game, accessible on both desktop and mobile, with smooth, minimalist graphics that let you focus on the intense gameplay. Your every move determines the fate of the world—navigate with precision using intuitive W/S or Z/S controls for propulsion and braking, and A/D or Q/D to steer your planetary ark. Right from the start, you’re immersed in the tension of space survival, equipped with a unique horizontal compass and responsive UI (while full 3D navigation is best on the downloadable version, browser play remains tightly engaging).

Every run is packed with challenge: plot your trajectory through cosmic hazards, make quick tactical decisions, and feel the rush as you narrowly escape solar devastation. Project Earth fuses classic retro sci-fi vibes with contemporary indie flair, making every attempt thrillingly fresh. It’s perfect for both casual players looking for quick action and hardcore gamers seeking tactical depth and replay value.

Created by a passionate indie developer—with even bigger adventures to discover on Steam—Project Earth is the kind of free online action game you’ll want to share and replay. Will you master celestial navigation and lead humanity into the stars? There’s only one way to find out: play now, and become the savior of Earth.

How to Play

Start your cosmic journey by loading Project Earth in your browser or mobile device. Your primary objective is to navigate Earth as a planet-ship away from the unstable, dying sun, successfully avoiding cosmic hazards en route to safety. Controls are intuitive: use W (or Z) to activate propulsion and move forward, and S for braking—timing is everything. Steer with A/D (or Q/D, depending on your keyboard), carefully plotting your course across the star system.

To select actions and confirm decisions, click with the left mouse button (or tap on mobile). Strategy matters: watch the horizontal compass (currently not fully functional in WebGL/browser, so anticipate extra challenges with direction), and monitor key stats displayed at the top of the screen. As you accelerate or brake, Earth's inertia changes—mastering this delicate balance is crucial to avoid overshooting your target or drifting into danger.

Beginner tips: Experiment with small adjustments rather than drastic steering changes. Don’t forget to keep an eye on your momentum, and use braking frequently in tight spots. Every attempt teaches you more about planetary navigation, so don’t get discouraged—each escape attempt builds your cosmic skills. Pause often to strategize, and remember: the fate of humanity is in your hands. Try the downloadable version on itch.io or Steam for a more complete experience, especially if you prefer full 3D navigation and a working compass.
