Tempest

O

Tempest is a 1981 arcade game by Atari Inc. The objective of Tempest is to survive as long as possible and score as many points as possible by clearing the screen of enemies that have appeared on the playing field. The player's ship can rapid-fire shots down the tunnel, destroying any enemies within the same segment, and is also equipped with a Superzapper, which destroys all enemies currently on the playfield once per level. (A second use of the Superzapper in a level destroys one random enemy.) Enemies swirl around at the far end of the playfield, then enter the playfield and move toward the player. There are multiple types of enemy, each of which has different behavior.
