## What is TankDuo?

TankDuo is an original retro tank defense roguelite for iPhone, iPad, and Apple TV.

Drive through brick walls, steel barriers, water, grass, and ice as you defend the base and clear enemy waves. From Chapter 2, every chapter's fourth stage defends a central base under attack from all four corners. Each stage has a randomized map, while enemy pressure, danger mechanics, and bosses keep escalating.

Features:

- On iPhone/iPad, move with the left directional control and hold the right button to fire; the cannon follows your movement direction
- Endless wave-based stages with randomized maps and escalating enemies
- A boss every five stages plus armor, charge, split, heal, and tracking mechanics; from Chapter 2, every chapter's fourth stage is a center-base siege
- Roguelite builds with one main cannon, two automatic weapons, and one support module
- Evolutions: fuse two maxed upgrades into a golden evolution card
- Combat Rating H0 to H8 with stacking affixes and higher score multipliers
- 29 achievements with offline tracking and optional Game Center and iCloud progress sync
- Blizzard cold waves slow nearby enemies; evolve it into Cryo Storm
- Automatic checkpoint each stage, resumable from the main menu at any time
- Scrap pickups for upgrade rerolls and tank repairs
- Destructible brick walls and steel that maximum firepower can break
- Six power-ups: star, helmet, grenade, clock, shovel, and extra life
- Five enemy classes, escalating waves, score, high score, highest-stage, and most-destroyed records
- Wave spawn warnings and four-way arrows that point at whatever is hitting the base
- Two-controller local co-op on Apple TV, with revives, friendly-fire stun, and independent upgrade choices
- Solo touch play on iPhone/iPad; solo or two-player couch co-op on Apple TV
- Original hard-edged pixel art, chiptune music, and procedurally generated retro sound effects
- No ads, no in-app purchases, and no account required

iPhone and iPad offer single-player gameplay. Apple TV local co-op requires two full game controllers connected to the same television device. No second iPhone/iPad or multiplayer room is required.

TankDuo is inspired by the pacing of classic top-down base-defense games. Its name, stages, artwork, icon, music, and sound effects are original.

### 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.
