   Doom II, also known as Doom II: Hell on Earth, is a 1994
   first-person shooter game developed and published by id
   Software for MS-DOS. It was also released on Mac OS the
   following year. Unlike the original Doom, which was initially
   only available through shareware and mail order, Doom II was
   sold in stores, making it the first game in the Doom franchise
   to be released initially in stores.

   Compared to its predecessor, Doom II features larger levels,
   new enemies, a new Super Shotgun weapon, and a new power-up.
   Master Levels for Doom II, an expansion pack with 21 new
   levels, was released on December 26, 1995. Another expansion,
   No Rest for the Living, which adds nine extra levels, was
   developed for the release of the game on Xbox Live Arcade and
   is also included in the Doom 3: BFG Edition, as part of Doom
   Classic Complete, and as a free add-on for the 2019 Unity
   engine port of Doom II. It was also included in the 2024 KEX
   Engine port.

   Reception of Doom II was very positive, with critics praising
   that the game refined the already good aspects of the original
   Doom. It has sold more than 1.8 million copies and earned over
   $74 million in revenue in the United States alone and is
   considered to be one of the greatest video games ever made.

   Doom II was ported to the Game Boy Advance in 2002, Tapwave
   Zodiac in 2004, on Xbox Live Arcade in 2010, and on Nintendo
   Switch, PlayStation 4 and Xbox One in 2019. The release of the
   Doom source code has facilitated ports to platforms including
   iOS and other cellphone systems. Doom II was included in the
   Doom ports for the PlayStation and Sega Saturn in 1995 and
   1997.

Gameplay

   [edit]
   [IMG]The Super Shotgun in use

   Doom II was not dramatically different from its predecessor.
   There were no major technological developments, graphical
   improvements, or substantial gameplay changes. Instead, the
   development team took advantage of advances in computer
   hardware since the release of the original game that allowed
   them to do more with their game engine by making much larger
   and more intricate levels. The game still consists of the
   player navigating large nonlinear levels. Each level is
   infested with demons that can be killed with a variety of
   weapons that can be picked up throughout the game. Levels are
   completed by finding an exit, whether it be a switch or a
   teleporter; the goal is simply to advance to the next area. As
   with its predecessor, Doom II's levels can be completed in a
   straightforward fashion. However, because the levels are
   nonlinear players can wander off the beaten path, and those
   that do are often rewarded with bonuses, like health pickups
   and more powerful weapons. Due to the larger and more
   complicated maps with larger groups of monsters, the game had
   somewhat higher system requirements than the original.

   Rather than the player playing through three related episodes
   as in the first Doom, gameplay takes place over 32 levels (two
   of which are secret levels that can be accessed from level
   15), albeit with interludes for when the story develops.
   Instead of watching the player's progress on a map (as in the
   original episodes of Doom), the screens between each level
   simply show a background (a style carried over to the bonus
   fourth episode of Doom available in The Ultimate Doom, the
   retail re-release of the original Doom). This also means the
   player is never forced to lose all of their inventory after
   completing an episode.

   Doom II doubled the number of non-boss monster types and
   started using bosses from the original Doom as normal level
   enemies, in addition to adding a new weapon, the super shotgun
   (a very powerful double-barreled shotgun), and a new power-up,
   the megasphere.

  Multiplayer

   [edit]

   Doom's multiplayer functionality was greatly improved in Doom
   II, including "out of the box" support for a vastly increased
   number of dial-up modems. The two-player dial-up connection
   allowed one player to dial into the other player's computer in
   order to play either cooperatively or in deathmatch-style
   combat. There was also local area network (LAN) functionality
   added, which was improved upon as patches and updates were
   released. This functionality was later incorporated into the
   original Doom. As with the original Doom, multiplayer games
   used to be played using the dial-up or LAN by the internal
   setup program (setup.exe), through the online service DWANGO
   or with once-popular programs like Kali and Kahn (using SPX)
   in Windows 95. Nowadays, in the modern standards, Doom II can
   be played with almost any version of Windows across the
   internet using third-party source ports such as Odamex,^[5]
   Zandronum,^[6] ZDaemon,^[7] and are still popular today.^[8]
   The Xbox Live Arcade port of Doom II supports online
   multiplayer via Xbox Live.

Plot

   [edit]

   Immediately following the events in Doom, the player once
   again assumes the role of Doomguy. After defeating the Spider
   Mastermind, the marine finds a portal to Earth opened by
   demons. After returning to Earth, the marine finds that it has
   also been invaded by the demons, who have killed billions of
   people.^[9]^[10]

   The humans who survived the attack have developed a plan to
   build massive spaceships which will carry the remaining
   survivors into space. Unfortunately, Earth's only ground
   spaceport has been taken over by the demons, who placed a
   barrier over it, preventing any ships from leaving.^[9] The
   marine battles hordes of demons and is able to deactivate the
   force field, allowing the remaining humans to escape. Once all
   the survivors have escaped Earth, the marine is the only human
   left on the planet.^[11]

   Just as he sits down to await death, knowing that he saved
   humanity, the marine then receives an off-planet transmission
   from the survivors in orbit, who have managed to find out
   where the armies of Hell are coming from. The message reveals
   that the demonic base is in the center of the marine's own
   hometown. He then fights through the city until he reaches the
   base, but sees there is no way to stop the invasion on that
   side. He decides to step into the portal to try deactivating
   it from the other side, entering Hell.

   After fighting through the hordes of Hell, the marine reaches
   the location of the biggest demon he has ever seen, called the
   Icon of Sin (Baphomet). He kills the Icon of Sin by firing
   rockets into its exposed brain. Its death causes devastation
   in Hell, and the portal to Earth is sealed. The marine wonders
   where evil people will go when they die now that Hell has been
   destroyed, and reflects that rebuilding the world will be more
   fun than saving it as he begins his journey back home.

Development

   [edit]

   Most of the levels were designed by Sandy Petersen,^[12] with
   American McGee playing a significant role as well.

   The final level, Icon of Sin, contains an easter egg where two
   of the artists put the severed head of John Romero as the
   sprite hidden behind the icon on the wall which must be
   damaged by rocket splash damage three times to win the game.
   Romero, while playing the level to work on its sound effects,
   accidentally stumbled upon this in-joke of himself. After
   realising what his co-workers had done, Romero himself
   answered by recording his voice saying "To win the game, you
   must kill me, John Romero", putting it through various filters
   to distort it, then reverse the recording to create the
   "demonic chant" spoken by the head upon spotting the
   player.^[13]^[14] The photo that was scanned for the "John
   Romero's head"-sprite was from a Businessweek photo shot in
   1994.^[15]

   One of Sandy Petersen's ideas that never made it to the final
   game was replacing the Fists weapon with a hand axe.^[16]

   Advertising for the game was between $3 million and $5
   million.^[17]

Releases

   [edit]

   Doom II was released for DOS on October 10, 1994 (one of the
   days of the Doomsday rule and exactly ten months after the
   original) in North America and Europe; distribution was
   handled by GT Interactive.^[18]^[19]^[20]^[21]

   In 1995, a port for Mac OS by Lion Entertainment Inc. was
   released,^[22] as well as a port for the
   PlayStation.^[citation needed] An Atari Jaguar port was also
   announced early in the year, but was never released.^[23]
   Likewise, a 3DO Interactive Multiplayer version was announced
   to be in development by Art Data Interactive, but it never
   materialized.^[24]^[25] In 1997, a port for the Sega Saturn
   was released.^[citation needed]

   A port for the Game Boy Advance was released in 2002, for the
   Tapwave Zodiac in 2004, for Xbox Live Arcade in
   2010,^[26]^[27] and for Nintendo Switch, PlayStation 4 and
   Xbox One in 2019, with the latter-most platforms (with
   PlayStation 5 and Xbox Series X/S versions) receiving a
   further expanded port in 2024 alongside the original
   Doom.^[28]^[29]^[30]^[31]

   The release of the Doom source code^[when?] has facilitated
   ports to many other platforms, including iOS and other
   cellphone systems.

   In August 2024, Bethesda announced a definitive edition at
   QuakeCon called Doom + Doom II. The new edition also includes
   TNT: Evilution, The Plutonia Experiment, Master Levels for
   Doom 2, No Rest for the Living, Sigil (by John Romero), a new
   deathmatch map pack with 26 maps, and a new episode titled
   Legacy of Rust. Legacy of Rust was developed by id Software,
   Nightdive Studios, and MachineGames. The bundle also included
   in-game mod support across both titles, along with the 2016
   "IDKFA" arranged soundtrack for Doom and a brand new "IDKFA"
   arranged soundtrack for Doom II, both by Andrew Hulshult.^[32]

   On 10 April 2025, Sigil II was officially added to the Doom +
   Doom II edition.^[33]

Expansions

   [edit]

  Master Levels for Doom II

   [edit]

   Master Levels for Doom II is an official expansion pack for
   Doom II which was released on December 26, 1995 by id
   Software.^[34] The CD contains 20 WAD files created by various
   authors under contract. There is also a bonus called Maximum
   Doom consisting of over 3,000 homebrew levels.^[35] Romero
   wrote about the origin of the expansion in 2023. Back in 1995,
   some retailers were selling disks in stores that simply
   contained many Doom WADs scraped from the internet. Though the
   levels were available for free online, many players had slow
   internet access at the time and so would purchase the disks,
   which were "selling like hot-cakes". Realising this, id
   decided to officially license a similar disk by approaching
   mappers and commissioning them for levels, in addition to the
   large shareware collection. More broadly, the disk was part of
   an effort by Romero to diversify id Software's income at a
   time when much of the team was waiting for the Quake engine to
   be ready.^[36] Reviewer Ed Dawson for PC PowerPlay praised the
   quality of the levels, but noted the "uniformly medium size"
   of the commercial levels and the high purchase price for
   predominantly shareware content.^[37]

  No Rest for the Living

   [edit]

   No Rest for the Living is an expansion pack developed for the
   release of Doom II on Xbox Live Arcade for the Xbox 360. It
   was developed by Nerve Software, under the direction of id
   Software and was released on May 26, 2010.^[38] It consists of
   eight regular levels and one secret level. It is also included
   in the 2012 Doom II release from Doom 3: BFG Edition, as part
   of Doom Classic Complete for the PlayStation Network, and has
   been released as a free add-on for the 2019 Unity engine port
   of Doom II. Although no detailed plot information is given,
   this expansion appears to take place after the main campaign
   of Doom II. Brandon James, president of Nerve Software, said
   this expansion was designed to be played on Ultra-Violence
   difficulty, contains "a plethora of secrets to find," and "is
   geared toward a more hardcore experience."^[39]

  Legacy of Rust

   [edit]

   Legacy of Rust was developed by id Software, Nightdive
   Studios, and MachineGames. Released on August 8, 2024, Legacy
   of Rust is the first official episode since Doom II to feature
   brand-new enemies/weapons. The new episode is divided into two
   chapters, "The Vulcan Abyss" and "Counterfeit Eden," which
   contain a combined total of 16 maps.^[40]

   The reception of Doom II was positive, with reviewers saying
   it refined everything that made the original Doom good.^[52]
   The game was reviewed in 1995 in Dragon #216 by David "Zeb"
   Cook in the "Eye of the Monitor" column, who stated that, "if
   mindless but intense carnage is what you want, you'll get your
   money's worth. It's just not a must-have,
   keep-on-the-hard-drive-forever game. If you need to have more
   Doom, get this."^[53]

   Writer/game designer Chris Crawford used the level "Barrels O'
   Fun" to illustrate a point about death in video games,
   explaining he chose the level as his example because it is
   "one of the most complex and sophisticated challenges in one
   of the very best games of the 1990s".^[54]

   Next Generation reviewed the PC version of the game, rating it
   three stars out of five, and stated that "Now that the first
   person interface has become the design of choice for the
   entire industry, Id will need to find new innovations, or it
   will quickly find it's playing catch-up in its own game
   niche."^[46]

  Awards

   [edit]

   Doom II won the Origins Award for Best Fantasy or Science
   fiction Computer Game of 1994.^[55]

  Sales

   [edit]

   According to David Kushner in Masters of Doom, id Software
   shipped 600,000 units of Doom II to stores in preparation for
   its launch. This initial shipment sold out within a month on
   shelves, despite its being expected to last for three
   months.^[56] Pre-orders for the game were so massive that it
   was difficult to buy from a store. The game products were
   displayed on pallets rather than shelves.^[57] The game was
   the United States' highest-selling software product of
   1994,^[58] and sold more than 1.2 million copies within a
   year.^[59] It placed 10th for 1996, with 322,671 units sold
   and $12.6 million earned in the region that year alone.^[60]
   According to PC Data, which tracked sales in the United
   States, Doom II sold 1.81 million units and earned $74.7
   million in revenue in the United States. This led PC Data to
   declare it the country's third-best-selling computer game for
   the period between January 1993 and April 1998.^[61] Its
   revenues in that country ultimately reached $80 million, while
   those in Europe reached $20 million. Of the latter figure,
   Kushner wrote that "30 percent [...] came from Germany—a
   country that had banned the game from its shelves."^[56]

   In Australia, the game sold 10,000 copies in the first two
   days of its release.^[62]

Legacy

   [edit]

   In 2022, John Romero created a new level called "One
   Humanity"^[63] for the game to raise money for the Ukrainian
   Red Cross, and the United Nations Central Emergency Response
   Fund following the outbreak of the 2022 Russian invasion of
   Ukraine.^[64]^[65]^[66] By March 2022, the new level had
   raised more than $29,000.^[67]
