Defender (1981 Video Game)

''Defender'' is a scrolling shooter video game developed by Williams Electronics in 1980 and released for arcades in 1981. A side-scrolling shooter, the game is set on either an unnamed planet or city (depending on platform) where the player must defeat waves of invading aliens while protecting astronauts. Development was led by Eugene Jarvis, a pinball programmer at Williams; ''Defender'' was Jarvis' first video game project and drew inspiration from ''Space Invaders'' and ''Asteroids''. ''Defender'' was demonstrated in late 1980, before entering production in early 1981. It was distributed in Japan by Taito.

''Defender'' was one of the most important titles of the golden age of arcade video games, selling over 55,000 units to become the company's best-selling game and one of the highest-grossing arcade games ever. Praise among critics focused on the game's audio-visuals and gameplay. It is frequently listed as one of Jarvis' best contributions to the video game industry and one of the most difficult video games. Though not the first game to scroll horizontally, it created the genre of purely horizontal scrolling shoot 'em ups. It inspired the development of other games and was followed by sequels and many imitations.

Several ports were developed for contemporary game systems, most of them by either Atari, Inc. or its software label for non-Atari platforms, Atarisoft.

Gameplay

''Defender'' is a side-view, horizontally scrolling shooter set on the surface of an unnamed planet. The player controls a spaceship flying either to the left or right. A joystick controls the ship's elevation, and five buttons control its horizontal direction and weapons. The player starts with three "smart bombs", which destroy all visible enemies. As a last resort, the "hyperspace" button works as in ''Asteroids'': the player's ship reappears in a random—possibly unsafe—location. Players are allotted three ships at the start of the game; another ship and smart bomb are awarded every 10,000 points (adjustable per machine). Two players can alternate turns.

The object is to destroy all alien invaders, while protecting astronauts on the landscape from abduction. Landers pick up humans and attempt to carry them to the top of the screen at which point they turn into fast-moving mutants. A captured human can be freed by shooting the lander, then catching the human before it falls to its death, and dropping it off on the ground.

Defeating the aliens allows the player to progress to the next level. Failing to protect the astronauts, however, causes the planet to explode and the level to become populated with mutants. Surviving the waves of mutants results in the restoration of the planet. A ship is lost if it is hit by an enemy or its projectiles, or if a hyperspace jump goes wrong (as they randomly do). After exhausting all ships, the game ends.

Development

''Defender'' was Williams Electronics' first attempt at developing a new video game; the company's earlier game was a ''Pong'' clone. The popularity of coin-operated arcade games in 1979 spurred the company to shift its focus from pinball games to arcade games. The company chose Eugene Jarvis, who had a successful record of Williams pinball games, to head development. Larry DeMar, Sam Dicker, and Paul Dussault assisted Jarvis. At the time, Williams had a small staff and the management was unfamiliar with technology used for its electronic games. As a result, the staff was afforded a large amount of creative freedom.

Initial development

Space was a popular setting for video games at the time, and Jarvis felt the abstract setting would help obscure simple graphics that lacked realism. Initially, Jarvis spent 3–4 months developing color variations of Taito Corporation, Taito's ''Space Invaders'' and Atari, Inc., Atari's ''Asteroids''. First inspired by ''Space Invaders'', he created a similar game with new gameplay mechanics. After spending a few weeks on the design, however, the team abandoned the idea, believing it lacked enjoyment. Development then shifted to emulating Atari's ''Asteroids'', but hardware differences between ''Asteroids'' and ''Defender''s proposed specifications were problematic. ''Asteroids'' displays vector graphics on a special monitor, while the staff planned to use pixel graphics on a conventional monitor. The team experimented with recreating the game with pixel graphics, but also abandoned it because they felt the gameplay lacked enjoyment and visual appeal.

Believing their first attempts to be too derivative, the developers held brainstorming sessions. During a session, they agreed that one of ''Asteroids''s favorable elements was its Wraparound (video games), wraparound. They felt a game that allowed the player to fly off the screen would be exciting, and decided to create a game world larger than the screen displayed. The game's environment was made longer than the screen, with the visible area scrolling horizontally. Expanding on the idea, they envisioned a version of ''Space Invaders'' rotated 90 Degree (angle), degrees. By changing the orientation of ''Space Invaders'' design, the ship moved up and down while flying horizontally. Large asteroids, an element from ''Asteroids'', were then added to the game world, but were later removed because the staff felt it lacked enjoyment. Jarvis intended the screen to scroll only from left to right; fellow Williams employee Steve Ritchie (pinball designer), Steve Ritchie, however, convinced him the game should be able to scroll in either direction.

After six months of development, the team felt the game had not made enough progress. They examined other games and concluded that survival was a necessary component to implement. To achieve this, they devised enemies to present a threat, the first of which was the "Lander". Jarvis enjoyed violent, action entertainment, and wanted the game to have those elements, but felt the action should have a reasonable objective. Inspired by the 1960s television show ''The Defenders (1961 TV series), The Defenders'', Jarvis titled the game ''Defender'', reasoning that the title helped justify the violence. He added astronauts to expand on the space theme and give players something to defend while they shot enemies. The element of flying over a planetscape was added after a brainstorming session between Jarvis and Ritchie. The landscape is depicted as a line only a pixel wide, primarily because the hardware was not powerful enough to generate anything more detailed.

Later development

By July, development was behind schedule and Jarvis's superior began to pressure him to finish the game in time for a then-upcoming trade show, the AMOA, in September. Jarvis spent several weeks creating the astronauts, which his boss felt should be omitted if the process didn't speed up. The pressure frustrated him to the point he considered resigning. Around that time, a new programmer named Sam Dicker was hired. He assisted in programming the game and added visual and audio effects. For example, Dicker implemented a particle effect algorithm to generate unique explosions for destroyed enemies. The new elements re-invigorated Jarvis, who felt the project began to show promise.

Development then shifted focus to the enemies. Landers were given the ability to capture humans, and a new enemy was devised from the mechanic: "Mutants", captured humans that had turned hostile. The Mutants added a rescue element to the game that Jarvis believed made it more interesting to players and encouraged them to continue playing. The element of making a "comeback" from a dire situation was applied to the planet as well. Jarvis felt it mimicked the ups and downs of real life. "Bombers", enemies which release floating bombs on the screen, were added next. More enemies were added to create different gameplay elements. "Swarmers" and "Pods" were designed to attack the spaceship as opposed to the astronauts. "Baiters" were included to add pressure to the player by preventing them from lingering. The enemies quickly follow the spaceship to collide with it, and were based on a similar enemy in ''Asteroids''.

By September, the game was still unfinished, and almost every Williams programmer assisted in meeting the deadline for the AMOA trade show. The evening before the trade show, the arcade cabinets were delivered for display. The developers, however, forgot to create an attract mode (an automated sequence designed to entice an audience to play) and high score system for the game, and began working on them that night, with DeMar coding the attract mode, Dussault and Dicker creating the high score table, and Jarvis doing playtesting and bug fixes. Early the next morning, the team created the final EPROM chips for the mode and installed them in a cabinet. The chips were put in backwards, causing an electrical short when the cabinet was turned on, so the team had to quickly burn a new set of EPROMs. Once the attract mode was operational, Jarvis and the team returned to their homes to prepare for the show. After the show, the developers expanded the game to allow users to play indefinitely. The display model featured five levels, which the team felt was more than enough because of the game's difficulty. Most Williams employees could not progress past the third level and Jarvis's score of 60,000 points seemed unbeatable to them. The developers decided it was best to be prepared for players that might exceed their expectations and added more levels that repeated.

Hardware

The game features amplified monaural sound and Raster graphics, pixel graphics on a Cathode-ray tube, CRT monitor. A Motorola 6809 central processing unit handles the graphics and gameplay, while a Motorola 6800 microprocessor handles the audio. A pack of three AA battery, AA batteries provide power to save the game's settings and high scores when the machine is unplugged from an electrical outlet. The cabinet artwork is stenciled on the wooden frame.

Development started by focusing on the game's hardware. The staff first debated what type of monitor to use: black-and-white or color. They reasoned that using advanced technology would better establish them as good designers and chose a color monitor. The developers estimated that the game would require 4 colors, but instead chose hardware that could display each pixel in 16 colors. At the time, the designers believed that was more than they would ever need for a game. The monitor's resolution is 320×256, an expansion from the then-industry standard of 256×256. The staff believed that the wider screen provided a better aspect ratio and would improve the game's presentation. Video games at the time relied on hardware to animate graphics, but the developers decided to use software to handle animation and programmed the game in assembly language. The switch allowed them to display more on-screen objects at a lower cost.

The game's control scheme uses a two-way joystick and five buttons. Jarvis designed the controls to emulate both ''Space Invaders'' and ''Asteroids'' simultaneously. The player's left hand manipulates the joystick similar to ''Space Invaders'' and the right hand pushes buttons similar to ''Asteroids''. The button functions also use a similar layout to ''Asteroids'', with the button to shoot projectiles and accelerate on the far right and left, respectively. Jarvis reasoned that players were accustomed to the control schemes of past games, and felt altering past designs would prove difficult for them.

Reception

Commercial performance

The game was slow to gain popularity, not attracting much attention at the 1980 AMOA show. In retrospect, Jarvis believed many passersby were intimidated by its complexity. The game was well-received in arcades, and crowds gathered around the cabinet during its first nights of play testing. The success spurred Williams to release a cocktail version as well. ''Defender'' eventually became Williams' best-selling arcade game, with over 55,000 units sold worldwide, and it became one of the highest grossing arcade games ever, earning over United States dollar, US$1 billion. , it has sold 70,000 arcade units and grossed worldwide.

Six months after its release, the game was one of the top earners in the United States video game industry. On the 1981 arcade game charts, it topped the ''Play Meter'' arcade chart in August, and the ''RePlay'' arcade charts for most months between April and November. The annual ''Cash Box'' and ''RePlay'' arcade charts listed ''Defender'' as the second highest-grossing 1981 in video games, arcade game of 1981 in the United States, just below ''Pac-Man''. The Amusement & Music Operators Association (AMOA) later listed ''Defender'' among America's six highest-grossing 1982 in video games, arcade games of 1982.

Co-designer Larry Demar was surprised by the game's popularity. At the time of its release, Stan Jarocki, director of marketing at then-competitor Midway Games, Midway Manufacturing,Williams Electronics purchased Midway in 1988, and later transferred its games to the Midway Games subsidiary. described the game as "amazing".

In Japan, ''Defender'' was not as highly successful, but was a moderate success. It was tied with ''Turbo (video game), Turbo'' and ''Galaxian'' as Japan's 18th highest-grossing 1981 in video games, arcade video game of 1981.

The Atari VCS port sold over copies, becoming the second best-selling Atari 1982 in video games, home video game of 1982 (just below the Pac-Man (Atari 2600), Atari version of ''Pac-Man''). However, at least 68,993 copies of ''Defender'' were Video game crash of 1983, returned in 1983. Via

Reviews

''Softline (magazine), Softline'' in 1983 wrote that it "remains one of the hardest arcade games ever developed. Initial attempts lasting less than ten seconds are not uncommon for novices".

Ed Driscoll reviewed the Atari 2600 version of ''Defender'' (where, due to its graphical limitations, was reformatted to a city setting, rather than the planet setting of the original arcade version) in ''The Space Gamer'' No. 57. Driscoll commented that "all in all, if you want a good game for your Atari, this qualifies. ''Defender'' lovers have a few gripes, but I would recommend this one to any VCS owner". The port won the "Best Science Fiction/Fantasy Videogame" category in the 1983 Arcade Awards. ''Computer and Video Games'' later reviewed the game, giving it a 90% rating.

In 1983 ''Softline'' readers named the Atari 8-bit version fifth on the magazine's Top Thirty list of Atari programs by popularity. The magazine was more critical, stating that "the game's appeal does not justify its unreasonable cost" of being shipped on ROM cartridges. David H. Ahl of ''Creative Computing (magazine), Creative Computing Video & Arcade Games'' said in 1983 that the Atari 5200 version was "a substantial challenge to the most seasoned space gamers". ''Computer Games'' magazine reviewed the IBM PC conversion, giving it a mixed review. They said the "action is very fast" but "it becomes boring after a short time."

Retrospective

In 1995, Flux (magazine), Flux magazine rated Defender 34th in its Top 100 Video Games. They lauded the game stating: "the ultimate side scrolling arcade shooter." ''Next Generation (magazine), Next Generation'' ranked the arcade version as number 13 on their 1996 "Top 100 Games of All Time", saying that its balanced difficulty makes gamers keep coming back for more instead of giving up. In 1996, GamesMaster (magazine), GamesMaster listed the game number 5 in their "Top 100 Games of All Time", they described the game as "One of the greatest shoot-‘em-ups of all time." In 1999, ''Next Generation (magazine), Next Generation'' listed ''Defender'' as number 23 on their "Top 50 Games of All Time", commenting that "despite exceptionally complicated controls, gamers fell in love at first sight. The difficulty is high but fair - when you die, it's always your fault, and that leaves you wanting one more chance to beat the game". In 2004, ''Defender'' was inducted into GameSpot's list of the greatest games of all time. In 2008, Guinness World Records listed it as the number six arcade game in technical, creative, and cultural impact. That same year, ''Retro Gamer'' rated the game number ten on their list of "Top 25 Arcade Games", citing it as a technical achievement and a difficult title with addictive gameplay. Also in 2008, ''Edge (magazine), Edge'' ranked ''Defender'' the sixth best game from the 1980s. The editors described its design as very "elegant" despite a lack of narrative and characters.

GameSpy's David Cuciz lauded ''Defender''s challenging gameplay, commenting that it is representative of what other games should be. He described the graphics as "beautiful", citing the varied sprites and flashing explosions. Matt Barton and Bill Loguidice of ''Gamasutra'' stated the audio-visuals and gameplay's depth balanced the excessive difficulty. They praised the game's "catch and rescue" feature, as well as the mini-map. Cuciz also praised the mini-map, stating that the game is impossible without it and that it allows players to plan strategies. Author John Sellers praised the audio-visuals and the connection between the game's plot and gameplay.

GameDaily in 2009 rated ''Defender'' the ninth most difficult game, citing the attack and rescue gameplay. Author Steven L. Kent called it "one of the toughest games in arcade history". He also stated that novice players typically are able to play only a few seconds, and that enthusiasts saw proficiency at the game as a "badge of honor". David Cuciz echoed similar comments. Sellers described ''Defenders difficulty as "humbling", saying that few could play it with proficiency. He further stated that players would continue to play despite the difficulty. Author David Ellis attributes the game's success to its challenging design. Its difficulty is often attributed to its complex control scheme. ''Edge'' magazine called ''Defender'' "one of the most difficult-to-master" games, describing its controls as "daunting".

Impact and legacy

Players have competed to obtain the highest score at the game and the longest play time on a single credit. Competitive playing for the longest play time was popularized by Mario Suarez from Atlantic City, who played ''Defender'' for over 21 and a half hours in 1982 at the Claridge Casino Hotel in Atlantic City. It was authenticated by the facility and the many witnesses that watched along with the press of Atlantic City; the media attention spurred other players to attempt the same feat. Expert players exploited software bugs to extend the length of their play time. ''Defender'' was the focus of the first Twin Galaxies video game contest. Players in 32 cities simultaneously competed on the weekend of April 3–4, 1982. Rick Smith was the victor with a score of 33,013,200 which took 38 hours. One bug, related to how the game keeps track of scoring, allows players to earn a large number of "extra lives". Players can then use the extra lives to leave the game unattended while they rest. Other bugs allow the ship to avoid damage from the enemies, also prolonging the length of play.

''Defender'' is considered the first side-scrolling shoot 'em up, predating ''Scramble (video game), Scramble'' by two months. Professor Jim Whitehead described ''Defender'' as a breakthrough title for its use of full 2D motion, multiple goals, and complex gameplay that provides players with several methods to play. James Hague of Dadgum Games called ''Defender'' a landmark title from the 1980s. Stearny said that the game's use of scrolling helped remove design limitations associated with the screen. Cuciz stated that ''Defender''s use of scrolling introduced the "first true 'gaming environment'". He further said that though the game's mini-map feature had been introduced before, ''Defender'' integrated it into the gameplay in a more essential manner. Stearny described it as the most important space game in the early 1980s. He commented that its realism and technological advances pushed developers to create more popular games, citing ''Gorf'' and ''Phoenix (video game), Phoenix'' as examples. Vince listed the game as a classic title that introduced new technology, specifically scrolling. Ellis stated that prior to ''Defender'', companies designed video games to have a balanced challenge. They believed games should be easy enough to attract players, but difficult enough to limit play time to a few minutes; anything too challenging would dissuade players. Loguidice and Barton commented that ''Defender''s success, along with ''Robotron: 2084'', illustrated that video game enthusiasts were ready for more difficult games, which spurred developers to create more complex game designs.

Jarvis's contributions to the game's development are often cited among his accolades. Author John Vince considered him one of the originators of "high-action" and "reflex-based" arcade games, citing ''Defender''s gameplay among other games designed by Jarvis. Ellis said that Jarvis established himself as an early "hard-core" designer with ''Defender''. In 2007, IGN listed Eugene Jarvis as a top game designer whose titles (''Defender'', ''Robotron: 2084'' and ''Smash TV'') have influenced the video game industry. Barton and Loguidice stated that the game helped establish Williams and Jarvis as key figures in the arcade game industry. Sellers echoed similar comments. After the success of ''Defender'', Williams expanded their business by building a new facility and hired more employees. Before the expansion, Jarvis could work in isolation. But the influx of people created an environment he was unhappy with. He left Williams along with DeMar to found their own development company, Vid Kidz. The company served as a consulting firm to Williams and developed two games for them.

Remakes and sequels

The success of ''Defender'' prompted Williams to approach Vid Kidz, who originally wanted to create a new game. DeMar, however, suggested creating an enhanced version of ''Defender'' to meet Williams' four-month deadline. Vid Kidz titled the game ''Stargate (1981 video game), Stargate'', and developed it as a sequel to ''Defender''. It features new elements and improved the original's performance. Some home ports of ''Stargate'' were released under the title ''Defender II'' for trademark purposes.

Williams released a ''Defender''-themed pinball machine in 1982. It has many elements from the original game: sound effects, enemies, waves, and weapons. Williams produced fewer than 400 units.

Midway's 1991 ''Strike Force (video game), Strike Force'' is an arcade update to ''Defender'' in the same way that ''Smash TV'' is an update to ''Robotron: 2084''. Jarvis and DeMar assisted with the game, but it was not widely distributed.

Atari Corporation released ''Defender 2000'' in 1995 for the Atari Jaguar. It was written by Jeff Minter, who had previously updated ''Tempest (video game), Tempest'' as ''Tempest 2000''.

''Defender'' is included in the 1996 compilation ''Williams Arcade's Greatest Hits''.

In 1997, Tiger Electronics released a handheld edition of ''Defender'' with a grayscale LCD screen, which doubles as a keychain ornament.

A Defender (2002 video game), 2002 remake, published simply as ''Defender'', uses 3D computer graphics, 3D graphics and a third-person viewpoint. It was released for the Xbox, GameCube, and PlayStation 2.

Influenced games and clones

Home games that copied ''Defender''s design include ''Gorgon (video game), Gorgon'' (1981) and ''Repton (1983 video game), Repton'' (1983) for the Apple II, ''Alien Defense'' (1981) for the TRS 80 Model III, ''Defender 64'' (1983) and ''Guardian'' (1984) for the Commodore 64, ''Invasion of the Body Snatchas!'' (1983) for the ZX Spectrum, ''Dropzone'' (1984) for the Atari 8-bit family, and for the BBC Micro ''Defender'' (1982) was renamed to ''Planetoid'' (1984) to avoid litigation. It influenced Jeff Minter's ''Andes Attack'' for the VIC-20 home computer, and later his bigravitational ''Sheep in Space''.

Other games built upon the core concept of protecting people or vehicles along the ground in a horizontally scrolling world, such as ''Protector II'' for the Atari 8-bit family, ''Chopper Command'' for the Atari 2600, and ''Choplifter'', all three of which were released in 1982.

Later games influenced by ''Defender'' were ''Datastorm'' (1989) for the Amiga and ''In My Defense'' (2021) on Steam.

Cultural references

The game has been referenced in music: Lou Reed's song "Down At The Arcade" on his 1984 album ''New Sensations'', Manilla Road's song "Defender" on their 1982 album ''Metal (Manilla Road album), Metal'', Buckner & Garcia's song "The Defender" on their 1982 album ''Pac-Man Fever (album), Pac-Man Fever'', and the Beastie Boys' song "Body Movin'" on their 1998 album ''Hello Nasty''. Nerdcore rapper MC Chris mentions ''Defender'' in the chorus of his anthemic song "Never Give Up" from his 2008 album, ''MC Chris is Dead''. Other artists to have used sound effects from ''Defender'' include Aphex Twin (on "Mt Saint Michel + Saint Michaels Mount" and "Bucephalus Bouncing Ball"), and Limp Bizkit (used to censor swearing on the clean version of "My Generation"). The game was featured prominently in the music video for the Sheena Easton song "Almost Over You".

Tim Waggoner's 2004 novel ''Hyperswarm'' is based on the video game.

The game is used as a running gag in the film ''Avengers: Infinity War'', where Groot is playing the game despite being told not to.

In ''Ready Player One (film), Ready Player One'', the ship from ''Defender'' is referenced, mentioning its ability to jump into hyperspace.

In ''Wonder Woman 1984'', in the Shopping Mall scene, there is a ''Defender'' machine visible inside the Amusement Centre.

In the fourth episode of season 3 of ''NewsRadio'' entitled "Arcade", station manager Dave's addiction to Defender as a teenager returns when the station gets a Defender arcade machine to replace an unused sandwich machine.

Defender is one of many classic arcade games that appear in the Midway Arcade World in Lego Dimensions, as it is played in Gamer Kid’s level “Retro Wreckage”, both in the start of the level, as he is shown playing Defender on his phone while he has his headphones in and it is playable in Gamer Kid’s world using the Arcade Machine vehicle, which is a part of Gamer Kid’s Level Pack.
