Prepare to immerse yourself in an exhilarating planetary defense arcade experience with *Blue Defense: Second Wave*. This game builds upon the legendary, pick-up-and-play gameplay of the original 2008 hit, which many have celebrated as an "App Store classic." Engage in intense, accelerometer-based gameplay as you defend the Blue planet from waves of menacing Red and Green enemies. Your mission is to obliterate these threats using the innovative planet cannon, ensuring the survival of 6.8 billion lives that hang in the balance.

With a variety of game modes ranging from quick bursts to marathon sessions, *Blue Defense: Second Wave* promises endless entertainment. Whether you're aiming to conquer the all-new Gauntlet mode, striving to survive as long as possible in Infinite-Classic and Infinite-Quickstart modes, or honing your skills in Level select mode to earn over 200 medals, there's always a challenge waiting for you. The game also features 62 mode-based global leaderboards, encouraging you to compete with players worldwide.

Experience the thrill of taking out hundreds of enemies at once with the powerful planet cannon. Navigate through 64 all-new levels, facing off against 24 different enemy types. The updated retro art style adds a nostalgic yet fresh visual appeal to your gaming experience.

Control the action with both multitouch and tilt controls, which can be used simultaneously for a versatile gameplay experience. Tilt your device to shoot bullets upwards, unless you're in a zero-gravity environment. Use multi-target locking by double-tapping the screen to continue your assault, and master the planet cannon by tapping and dragging from the planet to aim and release to fire. Pause the game at any moment by double-tapping the planet.
