Dive into the neon river. Tilt to steer, tap to fire, chase every bridge across cyberpunk canyons in a retro vertical shmup built for one thumb, and 22 machines.
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
• Score-based sectors: every bridge you clear ramps difficulty and rewards
• 22 machines to unlock: stealth jets, tandem-rotor Chinooks, quad drones, the B-2, the Black Hawk escort, and more
• 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
TWO 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
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.
