The classic and wildly popular Discovery Cannon Challenge web and iPhone game has been fully re-imagined and updated for the iPhone and iPad!

Your NLOS tank is now set in beautifully rendered 3D environments. You'll need to calculate not only the velocity and elevation of your shots to hit the enemy targets, but also consider the rotation of your turret as you blast your way through nine dangerous missions. Intelligent enemies will advance and fire back, so you will have to either use your shields or pivot to cover points to avoid fire. Be mindful of your shot count and allied drops that provide power-ups like shields, additional types of weapons and more.

Features of the Cannon Challenge II include:
- 3D rendered environments
- Tank turret rotation for more accurate targeting
- Player tanks can move or use shields for avoiding incoming fire
- Intelligent enemies move and shoot back
- Power-up rewards include shields, ammunition and more
- Use of Gyroscope (iPhone 4) or Accelerometer to look throughout environment
- Stunning graphics optimized for iPhone 4 Retina Display
- Scoring posted to leaderboards
- In-game soundtrack or choose your own music background
- Randomized enemy placement on each play
