Invatris provides you with a great space shooting platform. Blow up all the boxes and obstacles created by the enemies. You are the only hope as you pilot your jet to defend your city. Destroy the black boxes at all costs other wise they will raise the ground and make it easy for the enemy to reach the city. Collect as many stars possible to obtain a high score. Your health bar is shown on the bottom left corner. You will stay alive and kill more enemies as long as your health bar is not empty. Collect several power ups and special weapons falling from the sky and use them to your advantage to hunt down all the invading enemies.
