COBALT NINE

Take flight through towers, forests, skybridges, and ravines in a single-player 3D drone action game.

Language Support
The interface and tutorials are available in English and Korean.

Assemble Your Airframe
Combine a frame, twin motors, weapons, armor, and a power cell across seven equipment slots. Find parts in five rarity tiers, upgrade them with chips, and tune your drone for speed, durability, firepower, or energy.

Master 3D Flight
Climb, descend, turn, boost, dive, and fly narrow routes between structures. Automatic targeting and firing let you concentrate on piloting. Manual fire and three active combat skills add extra options in battle.

Clear a 200-Stage Campaign
Fight through ten regions and 200 stages with a gradual difficulty curve. Battlefields include training rooftops, city streets, high-rise corridors, forests, storm zones, and cliff routes.

Collect Supplies
Recover blocks and supply items during combat. Optional rewarded ads can open supply capsules. The supply screen displays drop rates and guarantee thresholds, and duplicate parts grant upgrade chips. The current version has no real-money item purchases.

Ad Information
The game may show occasional interstitial ads after a defeat. Rewarded ads are optional. If an ad is unavailable or required privacy choices are incomplete, core gameplay remains accessible.

No account is required. Progress is stored locally on your device. An internet connection may be needed for ads.
