As a freshly graduated pilot of a small aircraft you must take off with as much cargo and as many passengers as you safely can, while avoiding terrain and obstacles. Earn points by pushing your airplane to it's limit, but beware: The more you carry, the worse your aircraft will perform! How many passengers and how much cargo can you successfully take off with, and still out climb obstacles and terrain? This game applies the real-world laws of aviation to a variety of challenging scenarios. As in the real world of flying, a headwind can be your ally. Wind reduces the speed at which you travel over ground, but it does not affect climb speed, so a strong headwind can provide pilots with a steep climb angle. Hot, High, and Heavy. Any combination of these can produce disastrous results. Hot or high atmospheric conditions indicate thin air, which reduces aircraft performance by lengthening the takeoff roll and reducing your climb angle. Too much weight will have the same effect on aircraft performance. Earn money, upgrade your plane. Complete achievements, earn gems, unlock new maps.

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 — because the radar is your only map. THREE GAMES IN ONE - CRUISE — Pure flight. No weapons, no boosters. Just you, gravity, and one perfect slingshot to the target. - COMBAT — Full war. Dodge mines, missiles, and asteroid lasers. Boosters and shields at your side. - ASSAULT — 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 — 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 — 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 — 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 — yours forever. Slingshot in. Master the pull. Clear the system.
