ALTITUDE ZERO is a fast, focused vertical shooter with a cyberpunk heart. Tilt your phone (or drag your thumb) to steer a jet, chopper, drone, or heavy bomber down a river carved from neon. Bridges divide the run into sectors: clear them to raise the stakes with faster scroll, tougher enemies, and richer payouts. No fluff. No timers gating your fun. Just a clean shmup loop, tuned for short sessions and long high-score chases. GAMEPLAY • One-thumb controls: gyro tilt with tap to fire, or full touch drag if you prefer • Pick your theater from a tactical operations map, each with its own threat rating, payout, and personal best • Score-based sectors: every bridge you clear ramps difficulty and rewards • 23 machines to unlock: stealth jets, tandem-rotor Chinooks, quad drones, the B-2, the Black Hawk escort, and the DARK STAR ion-fighter • Analytic river collision, no cheap deaths, no invisible walls • Weather that actually changes the fight: rain with lightning strikes, snow drifting the ship sideways, thick fog cutting your reach THREE MAPS • NEON RIVER, the classic cyberpunk canyon, wide and forgiving until it isn't • GRAND CANYON, narrow water, cliff-mounted missile launchers, dams, and a coin bonus for the brave • STAR RUN, trench walls and dense turret gauntlets in deep space, double coins for anyone who lives through it ESCORT AND POWER-UPS • Score milestones drop a Black Hawk escort with wingmen and a fuel hose • Contra-style pickups: SPREAD, RAPID, PIERCE, +1 HP • Bomb items and shield items on cooldown when a wave goes wrong PROGRESSION • 20+ Game Center achievements • Weekly and All-Time leaderboards • A hangar you actually want to grind for. Every ship flies differently. FREE TO PLAY, HONEST ABOUT IT • Free with ads. Banner ads between menus, a short interstitial after some runs, and optional rewarded videos that give you a continue or a coin top-up when you choose to watch them. • Coins are the in-game currency you spend on new ships. Earn them by playing, or buy a coin pack as an in-app purchase if you want to fast-track a specific ship. • Remove Ads (Pro) is a one-time in-app purchase that removes every ad in the game for good.
