In the distant future, Earth was attacked by an alien enemy known as xenomorphs. They used their technology to infiltrate Earth and take over. However, a hero emerged who decided to defend his planet. He gathered a team of other survivors and went into space to find a way to defeat the aliens. Our hero pilots a spaceship and must destroy enemies using various weapons on board. The player's goal is to protect Earth from alien invasion and save humanity. Rules: dodge collisions with alien ships, earn 5 points for each maneuver. Star dust clouds are our helpers โ they help us hide from the aliens, and you get 30 points for flying through them.
