Tempest

Tempest is a 1981 tube shooter video game developed and published by Atari, Inc. for arcades. It was designed and programmed by Dave Theurer. It takes place on a three-dimensional surface divided into lanes, sometimes as a closed tube, and viewed from one end. The player controls a claw-shaped "blaster" that sits on the edge of the surface, snapping from segment to segment as a rotary knob is turned, and can fire blaster shots to destroy enemies and obstacles by pressing a button. Tempest was one of the first games to use Atari's Color-QuadraScan vector display technology. It was also the first to let players choose their starting level (a system Atari called "SkillStep").
