A player runs a space ship loaded with different weapons. The ship can fly both vertically and horizontally within the borders of the game screen. At the beginning of each level the space is empty but during the flight certain enemy ships and obstacles appear on the screen. Enemies can fly freely on the screen making tricks and special moves. The purpose of the game is to kill as many enemy objects as possible, including asteroids. After a certain number of enemy objects is destroyed a player gets different bonuses, i. e. healing packs, weapons upgrades, double-power packs, etc. When the enemies are eliminated on the level, a player jumps to the next level. After completing every three levels you’ll meet a super-boss on your way – an enemy super space ship with tricky weapons and fight behavior.
The game offers many guns from common machine gun to plasma gun and ion shell. Homing missiles find targets themselves and help annihilate super tricky enemies.
In September 2015, a new study provided an important missing piece to the intriguing puzzle of how our Moon came to be the lovely object that we see today.
The screaming winds could be carrying the dust raised from the dunes across great distances, contributing to the global cycle of organic dust on Titan. These would result in effects similar to those that occur on both Earth and Mars.
A moon is a natural body that is in orbit around a planet, and it is kept in place by both the host planet's gravity and the gravity of the moon itself. Some planets possess orbiting moons; some do not. There are several theories explaining how Earth's Moon came to be. At this point, the favored model is termed the giant impact theory, often playfully called the Big Whack or Big Splash theory by astronomers when they are in a humorous frame of mind. These funny nicknames were derived from the central tenet of the theory, which is that a Mars-sized body, named Theia, smacked into the primordial Earth billions of years ago. The collision caused part of our planet's crust to be hurled violently into space. Some of this shattered, somersaulting debris was snared into Earth-orbit, where it formed a host of moonlets that were ultimately pulled together by gravity to evolve into our Moon.
