About Gravity Storm - First Mission (Demo 3)

Get ready to defy the natural laws of the universe in Gravity Storm - First Mission (Demo 3), a pulse-pounding action experience where every move could mean your escape or doom. As Project Gravity Storm, you awaken in a rogue facility where machines and deadly hazards await at every turn. Forget what you know about platformers—it’s time to bend gravity to your will! From the moment you launch the demo, every power is at your fingertips: dash in any direction, manipulate gravity, and unleash energy blasts to overcome relentless obstacles and malfunctioning machines. The browser-based HTML5 design means instant action—no downloads required—and seamless play across PC or mobile.

Gravity Storm stands out for its crisp, retro-inspired pixel graphics, immersive sound effects, and a level design that rewards creative solutions. One pathway might demand lightning reaction speed, while hidden routes let you cleverly exploit your gravity abilities. Every level is a new puzzle, tempting speedrunners and explorers alike. The mother computer—your relentless adversary—adapts as you play, ensuring that no two sessions ever feel the same.

Unlike typical action games, here you’re not just running and jumping—you're in command of the laws of physics! Float over deadly spikes, leap upside-down across ceilings, or dash through laser grids like a pro. The game’s accessible difficulty is perfect for beginners, but mastering the intricacies of gravity powers will challenge even experienced gamers. Each hazard is an invitation to experiment; each victory feels earned through skill and ingenuity.

Gravity Storm - First Mission is a brilliant showcase from the indie community. Playable for free via itch.io, or as a downloadable demo on Steam (wishlist it for updates!), it's a shining example of modern indie action—a must-play for anyone who loves energetic, physics-bending gameplay. Are you ready to face the rogue machines and escape the mother computer’s grasp?

How to Play

Getting started with Gravity Storm - First Mission is easy, but true mastery takes clever thinking! Launch the game directly in your browser (or try the downloadable demo) to take control of Project Gravity Storm: a powerful machine capable of shifting gravity, dashing, and firing energy blasts. Move your character using the arrow keys or WASD—left and right to run, up to jump. To reverse gravity and walk on ceilings or avoid traps, press the gravity-flip button (usually Space or G). Dashing is crucial for narrowly escaping hazards: hit Shift or a dedicated dash key to burst through danger. Use the mouse or a specific button (often J or Left Click) to fire your weapon and take down rogue machines.

Every level is loaded with traps, moving platforms, and aggressive foes managed by the unpredictable mother computer AI. Your objective: reach the exit by creatively outmaneuvering these threats using gravity shifts and quick reflexes. Collect power orbs to unlock bonus routes or hidden goodies. Watch out for long loading times in the browser version, and try the Steam demo for the smoothest experience. The easy difficulty setting makes Gravity Storm welcoming, but experiment with new routes and combos to improve your skills and aim for speedrun glory!

Beginner Tips:

1. Get comfortable with gravity switching before tackling complex hazards.

2. Study enemy patterns; the mother computer isn’t random—there’s always a trick.

3. Experiment! Sometimes the ceiling path is easier than it looks.

4. If stuck, scout for breakable walls or secret passages using your dash.
