## What is 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

Both devices must have compatible versions of the game installed and grant the required local network and Bluetooth permissions.

## Version history (last 4 releases)

### 1.3 — 2026-09-19

Fixed some issues.

### 1.2 — 2026-09-18

1. Redesigned the battle interface with side controls: a directional joystick on the left and a fire button on the right, leaving more room for the battlefield.
2. The turret now follows the movement direction. Hold a direction to fire continuously for smoother one-handed controls.
3. Redesigned the landscape menus, results screens, and in-game HUD to prevent the battlefield from being squeezed on smaller screens and iPad.
4. Fixed an issue where enemies could spawn repeatedly at the same spawn point and become stuck. Overlapping enemies now separate automatically.
5. The Shovel power-up now reinforces existing brick walls only, instead of creating steel walls from empty spaces.
6. Fixed edge cases involving the initial number of reactive armor layers and enemy-elimination calculations for splitting enemies.
