Tempest, released by Atari in 1981, remains one of the most visually and mechanically distinctive games of the golden age — built on vector graphics rather than the pixel-grid raster displays used by almost everything around it, and controlled by a rotary “spinner” knob instead of a joystick.
Vector Graphics, Explained
Most arcade monitors of the era drew images the way a television does: scanning a fixed grid of pixels line by line. Vector monitors work completely differently, drawing images as a series of precisely aimed straight lines directly traced by the electron beam, similar in principle to an oscilloscope. The result is a picture made of impossibly crisp, glowing lines rather than blocky pixels — vector games have a distinctive sharpness and brightness that raster hardware of the same era simply couldn’t replicate. Tempest’s abstract, glowing geometric “web” playfield is a direct showcase of what vector technology did best.
Dave Theurer’s Design
Tempest was designed by Dave Theurer, the same Atari designer behind Missile Command the year before. According to accounts from the time, Theurer developed Tempest partly out of a recurring nightmare about being chased and consumed by something crawling up out of a hole — a fittingly unsettling origin for a game about fending off creatures climbing up a geometric tube toward the player’s position at its rim. Whatever its psychological origins, the resulting concept — enemies advancing up individual lanes of an abstract 3D-ish tube toward you — was unlike anything else on arcade floors at the time.
The Spinner Controller
Tempest’s rotary spinner was one of the first genuinely analog control inputs in mainstream arcade gaming, letting players rotate their position around the tube’s rim with a level of fine, continuous precision a directional joystick simply can’t match. That analog feel became inseparable from the game’s identity — Tempest ports and clones on digital controllers have never quite recreated the exact responsiveness of the original spinner, which is part of why dedicated Tempest cabinets remain highly sought after specifically for their authentic control hardware rather than just the board inside.
Legacy and Spiritual Successors
- British game designer Jeff Minter has spent much of his career building spiritual successors to Tempest, starting with Tempest 2000 for the Atari Jaguar in 1994 — widely regarded as one of the best games on that commercially unsuccessful console — and continuing through later reimaginings like TxK.
- Tempest’s vector aesthetic influenced the visual style of numerous later games even after vector hardware itself largely disappeared from arcades by the mid-80s, as raster displays became cheaper and more versatile.
- Atari itself revisited the concept decades later, and the original remains a fixture of golden-age retrospectives specifically because it still feels genuinely different from anything released before or since.
Collecting Notes
Vector monitors are notably harder to source and service than standard raster arcade CRTs, since they use a different chassis design built specifically for the precise beam-steering vector graphics require — something worth understanding before buying a Tempest cabinet, since a failing vector monitor is a more specialized repair than a typical raster CRT issue. For collectors specifically drawn to the unusual hardware as much as the gameplay, that added complexity is part of the appeal rather than a deterrent.
