Sinistar is an arcade game released by Williams in 1982. It belongs to a class of video games called twitch games. Sinistar was developed by Sam Dicker, Jack Haeger, Noah Falstein, RJ Mical and Richard Witt. The title is also a pun on the word "sinister." The player pilots a lone spacecraft, and must create "Sinibombs" by shooting at drifting planetoids and catching the crystals that are thereby released. Sinibombs are needed to defeat the game boss, Sinistar, an animated spacecraft with a demonic skull face. Sinistar does not exist at the start of the game, and is continuously under construction by enemy worker ships. Though time is crucial, attempting to mine too quickly will destroy a planetoid without releasing any crystals. Enemy worker ships are also gathering crystals (often stealing them from the player) which they use to construct the Sinistar. Enemy warrior ships can directly attack the player's ship. The player is given a head-start before the enemy ships have enough crystals to begin construction. Game ends when the player's ships are all destroyed. Once the Sinistar is completely formed, a digitized voice (recorded by radio personality John Doremus and played through an HC-55516 CVSD decoder) makes various threatening pronouncements, including "Beware, I live!," "I hunger, coward!," "I am Sinistar!," "Run! Run! Run!," "Beware, coward!", "I hunger!," "Run, coward!," and various loud roaring sounds. The Sinistar has no weapon attacks, but if it contacts the player's ship while it darts about the playfield, the player's ship will be "eaten" and destroyed. A total of 13 Sinibombs are required to destroy a fully built Sinistar, although an incomplete Sinistar can be damaged to slow construction. Each short-range Sinibomb automatically targets the Sinistar when fired, but can be intercepted by a collision with an enemy ship, enemy fire, or a planetoid. The player moves from one zone to the next each time he defeats the Sinistar. A sequence of four zones...
