Asteroids and aliens are threatening your planet to a doom. You, as a space ranger should eliminate all these dangerous objects as quickly as possible, or you will be hit and crashed. Save the day by destroying the harmful forces! The asteroid will be broken down into smaller pieces, but you still need to fire at them until the fragments are completely destroyed. Your spacecraft will be under attack when an enemy appears, and you have to dodge from the missiles and fight back. Be careful when you move to the edges of the screen as your spaceship will rebound. If your craft is hit by an asteroid or a missile, the game ends. Turn [left and right arrow keys] Move [up and down arrow keys] Shoot [Spacebar]
