Navigate through the void. Survive the barriers. Escape the system. ARC 9 is a fast-paced arcade game where you pilot a ship trapped inside an ancient alien defense system. Massive energy barriers are closing in from all sides — each one a ring of force with only a single narrow gap. Your ship is locked in a fixed orbital path around the station core. The only way out is through. Tap the left or right side of the screen to fire your thrusters and rotate your ship into position. Time your movements carefully — the gaps shift as barriers close in, and the speed only increases the further you go. FOUR THREAT LEVELS Choose your challenge. Easy eases you in with wider gaps and slower barriers. Medium picks up the pace. Hard demands precision. Crazy is relentless — faster walls, tighter gaps, and rapid rotation. Each threat level has its own global leaderboard. EMERGENCY REVIVE Lost all your shields? You get one chance to revive with 3 fresh shields and keep pushing your score higher. ACHIEVEMENTS Unlock 25 achievements across sector milestones, lifetime stats, and skill challenges. Clear 100 sectors without losing a shield to earn INVINCIBLE. Play every threat level to unlock the PROMOTED Achievement! Track your progress in the Rankings tab. GLOBAL LEADERBOARDS Compete against pilots worldwide. Four separate leaderboards — one for each threat level. Submit your best scores through Game Center and see how you stack up. SHIP UPGRADES Remove Ads for uninterrupted gameplay. Grab Extra Shields to start every mission with 5 shields instead of 3. CUSTOMIZE YOUR EXPERIENCE Adjust thruster sensitivity, toggle sound effects, music, and vibrations. Fine-tune your setup in the Systems screen. FEATURES - Simple one-touch controls! Tap left or right to rotate - Progressive difficulty that scales as your score climbs - Synthesized ambient soundtrack that builds suspense - Haptic feedback on every ring pass and shield hit - Extremely smooth gameplay - Responsive design across all iPhone screen sizes No one has ever cleared Sector 100 on Crazy. Prove them wrong, pilot.
