The Earth is being attacked by alien invaders from another universe, and you, the hero, are the only one who can help save the planet. In this game, you will take on the role of one of the mecha knights. You were tasked with assisting in the survival of the Earth by stopping their attacks and defending the homeland. You must do your best at both dodging and striking your opponent. Take victory while protecting Mother Earth.

The game’s mechanics are simple; to keep your health, you must move and avoid the bullets coming your way while using the left-hand controls. Another approach is to use long-range weapons to damage the aliens by using right-hand controls, such as machine guns and missiles. Once you are in close proximity to the alien, you can automatically switch to using laser swords.
