Play Metal Sonics Asteroid Blaster
The action begins as soon as you press the Play button. Sonic will begin flying through the middle of the screen. You can move him higher or lower on the screen by using the up and down arrow keys. You can also slow him down by pressing the left arrow key and speed him up with the right arrow key.
You can help Sonic shoot at the asteroids by pressing the spacebar. What's interesting is the asteroids don't immediately disappear after being shot. They instead break into four smaller pieces. These pieces then shoot out in a diamond shape. Be sure you aren't too close to the pieces when they shoot out or your game will come to an end.
Directions
