littleDefender is our last hope against unknown alien invasion. There are a variety of alien spaceship from Star Gate, this will be the main goal we want to destroy. We must wisely use our weapons, but also from the wreckage of the enemy can get some loot, some of which will be very useful for us to defend the tougher enemies. At the same time, there is a strong unidentified object, we call it the 'helper'. The assistant will help us complete our work. When we need help, go to the helper.

Good luck.
