About

Gravity OB1

Features
Read full description

GRAVITY OB1 turns orbital physics into pure arcade thrill. Sling your ship across a living solar system, ride the pull of planets and black holes, and master gravity itself โ€” because the radar is your only map. THREE GAMES IN ONE - CRUISE โ€” Pure flight. No weapons, no boosters. Just you, gravity, and one perfect slingshot to the target. - COMBAT โ€” Full war. Dodge mines, missiles, and asteroid lasers. Boosters and shields at your side. - ASSAULT โ€” Take the fight to the enemy. Dogfight alien ships with a twin-stick control scheme, lock into orbit around planets, and rain fire on your foes. MASTER GRAVITY Every shot is a puzzle. Planets bend your flight path, black holes swallow the careless, and the sun is always hungry. Learn to read the pull, thread the needle, and let physics carry you home. ORBIT LOCK Fly close to any planet and lock into a stable orbit โ€” circle your target hands-free while your cannons and homing missiles pour fire into it. A gravity-powered gunship run like nothing else on mobile. A FLEET OF SHIPS Unlock 8 distinct ships, from the nimble Needle interceptor to the mighty Bastion battleship. Each flies differently โ€” light and fast, or heavy and armored but harder to pull free of gravity's grip. 100 MISSIONS + SUPER NOVA Ten levels across every mode, each with escalating hazards: moving asteroids, black holes, orbiting worlds, and finally the endless waves of Super Nova. FEATURES - Real gravity physics โ€” no two shots ever feel the same - Three completely different game modes - 8 unlockable ships with unique handling - 8 alien enemy types with distinct behaviors - Homing missiles, cannons, boosters, and shields - A tactical radar you'll learn to live by - Premium hand-crafted art and an original soundtrack Free to play the opening of every mode. Unlock the full campaign once โ€” yours forever. Slingshot in. Master the pull. Clear the system.
