It is a multidirectional shooter arcade game that is space-themed, released in 1979 by Atari. The player takes control of a single triangular spaceship in an asteroid field which gets disturbed by saucers and asteroids in its way. The ship can rotate left and right, thrust forward, and also fire forward shots. After the boat starts to move in a particular direction, it will continue to go in that direction until it gets some thrust in a different order. The ship can also go into hyperspace and can disappear and reappear anywhere on the screen. The game aims to shoot the saucers and the asteroids and avoid getting hit or colliding with them. As the game moves forward, the number of asteroids also increases. Like the hyperjump, there are nine effects that let asteroids spin fanatically as the player progresses through different rock paths. Each level begins with the asteroids moving in different directions. After the player hits the asteroids, they get broken into smaller pieces, and if the player hits these pieces, he gets more points. Two flying saucers occasionally appear on the screen; the big saucer aim is not great, but the smaller one frequently fires at the ship. After the player reaches 40,000 points, only the small saucer appears; as the player's points increase, the small saucer's angle range reduces, and after some time saucer fires extremely accurately. After the player has cleared all the asteroids and saucer, a new set of large asteroids appears and starts the next level. In the beginning, the player has 3–5 lives, and after every 10,000 points, there is an extra life. If the player loses all the lives, it ends the game. 99999 is the maximum high score that the player can achieve.
