TankDuo：双坦出击

“TankDuo: Twin Tanks Strike” is an original retro tank defense game created for iPhone and iPad. Drive your tank across brick walls, steel walls, water, grass, and ice. Defend the base at the bottom of the map and repel relentless waves of enemy forces. Four enemy types feature different speeds, firepower, durability, and point values, requiring you to balance offense and defense in every stage. Key Features: - Classic four-direction movement and firing controls - A continuous single-player campaign featuring three original maps - Destructible brick walls and steel walls that require maximum firepower to penetrate - Six power-ups: Star, Helmet, Bomb, Clock, Shovel, and Extra Life Tank - Four enemy types, wave-based spawning, lives, scoring, and local high scores - Two-player co-op between nearby devices, with the host running the battlefield and synchronizing the other player’s actions - Full-screen landscape support for iPhone and iPad - Original hard-edged pixel art and procedurally generated retro sound effects - No ads, no in-app purchases, and no account required Nearby two-player mode uses Apple’s MultipeerConnectivity framework. Depending on the environment, the system connects the devices using the local network, peer-to-peer Wi-Fi, or Bluetooth capabilities. Both devices must have compatible versions of the game installed and grant the required local network and Bluetooth permissions.
