Shoot 'em up (also known as shmup or STG) is a subgenre of the shooter genre of video games.
 In a shoot 'em up, the player character engages in a lone assault, often in a spacecraft or aircraft, shooting large numbers of enemies while dodging their attacks.
 There is no consensus as to which design elements compose a shoot 'em up.
 Some restrict the definition to games featuring spacecraft and certain types of character movement; others allow a broader definition including characters on foot and a variety of perspectives.
 Shoot 'em ups call for fast reactions and for the player to memorize levels and enemy attack patterns.
 "Bullet hell" games feature overwhelming numbers of enemy projectiles.
The Ghost Dance (Caddo: Nanissáanah, also called the Ghost Dance of 1890) was a new religious movement incorporated into numerous American Indian belief systems.
 According to the teachings of the Northern Paiute spiritual leader Wovoka (renamed Jack Wilson), proper practice of the dance would reunite the living with spirits of the dead, bring the spirits of the dead to fight on their behalf, make the white colonists leave, and bring peace, prosperity, and unity to Indian peoples throughout the region.
Space Pilot is a shoot 'em up game based on aircraft combat for the Commodore 64, released in 1984 by Kingsoft GmbH.

 The enemies also take the form of various aircraft, and fly in various directions.
 On each level, the player's task is to destroy a certain number of enemy aircraft, after which a "boss" enemy appears.
 Destroying this enemy advances the game onto the next level.
Douglas Alan Clark (died August 6, 2012.)
 is a recipient of the Navy Cross for his actions while commanding Fighting Squadron THIRTY (VF-30), attached to the USS Belleau Wood (CVL-24), on 21 March 1945.
 While on combat air patrol he directed his squadron to attack an enemy formation of Japanese bombers which was heavily protected by fighters.
 Even though his squadron was significantly outnumbered they were able to shoot down over 40 enemy aircraft in 30 minutes without suffering one loss.
 Lt Cmdr Clark himself shot down one enemy fighter and damaged another during the confrontation.
 His quick action and the superiority of his squadron turned back what would surely have been a devastating attack on his carrier group.

Perfect is the enemy of good is an aphorism, an English variant of the older "better is the enemy of good", which was popularized by Voltaire in French form.
 Alternative forms include "the perfect is the enemy of the good", which more closely translate French and earlier Italian sayings, or "[the] perfect is the enemy of [the] good enough".
 Similar sentiments occur in other phrases, including from English, and are all attested since around 1600.
Crow Dog (also Kȟaŋǧí Šúŋka; 1833 – 1912) was a Brulé Lakota subchief, born at Horse Stealing Creek, Montana Territory.
 He was the nephew of former principal chief Conquering Bear, who was killed in 1854 in an incident which would be known as the Grattan massacre.
 Crow Dog was one of the leaders who helped popularize the Ghost Dance.
 On August 5, 1881, after a long simmering feud, Crow Dog shot and killed principal chief Chief Spotted Tail (who was also at the Grattan massacre), on the Rosebud Indian Reservation.
 A grand jury was convened and he was tried and convicted in Dakota Territorial court in Deadwood, South Dakota, and sentenced to death which was to be carried out on January 14, 1884.

Zarlor Mercenary is an action game for the Atari Lynx handheld console, released by Epyx.
 It was a vertically scrolling shoot 'em up in which the player controlled a spacecraft destroying enemy spaceships and buildings in order to earn money which could be used to buy upgrades between levels.
 These upgrades included more powerful shots, side shots, regenerating shields, megabombs (damaging every enemy on the screen) and a laser which automatically targeted the nearest airborne enemy.
 Up to four players could play simultaneously, extra weapons being available to attack the other players.
Super Aleste (スーパーアレスタ ) , known in North America as Space Megaforce, is a vertically scrolling shoot 'em up video game developed by Compile.
 It was published by Toho in 1992 for the Super Nintendo Entertainment System as part of the "Aleste" series.
 In a traditional fashion, the player pilots a spaceship through a variety of locales crawling with enemy squadrons to shoot down, though the story in the Japanese version is different from American and European ones.
 However, "Super Aleste" also offers a "Short Game", where only a set of small levels are played, with the emphasis on scoring as many points as possible.
