The most classic of videogames revisited without betraying the original nature: the aliens move along the three axes in a "vintage way", and the UFO moves only along the upper perimeter: you'll have to defend the space platform from evil but amazing 3D space invaders, with the help of extra weapons and first person mode. You will get them shooting down the UFOs: triple fire, energy shield, self-guided missiles and paralyzing rocket. Totally new: cockpit mode, which will project you inside the Cannon, bringing yourself to the center of the battle, and capture mode, where you'll have to hit the alien that will have captured a laser cannon in order to fight using two cannons at once! You'll also get other new combined weapons by advancing level! And now there are also Boss Monsters every three levels!
