Chaotic Tanx

Artillery warfare on iOS with destructible terrain, physics-based ballistics, and turn-based multiplayer. Currently in TestFlight beta.

Chaotic Tanx is an artillery game for iOS in the tradition of Scorched Earth and Worms. Built with SpriteKit, it features destructible terrain, realistic ballistics with wind effects, and turn-based multiplayer via Game Center. Currently available on TestFlight.

🎮 Core Gameplay

Destructible Terrain System

  • Real-time crater generation - Permanent landscape modification
  • CGContext bitmap manipulation - Efficient terrain destruction
  • Physics body regeneration - Accurate collision detection after destruction
  • 60fps performance - Optimized for iPad (2022)

Weapon Arsenal

  • Basic Cannon - Simple projectile with medium-sized craters
  • Sunburst Launcher - Splits into 3-5 projectiles at trajectory peak
  • Strategic depth - Different weapons for different tactical situations
  • Visual weapon feedback - Distinct firing effects and impact patterns

Combat Mechanics

  • Intuitive aiming - Drag from tank to aim with visual arc preview
  • Power system - Distance determines projectile force
  • Physics simulation - Realistic ballistics and gravity effects
  • Screen shake - Impact feedback enhances combat feel
