When, three years later, 3D Realms released Duke Nukem 3D, a tongue-in-cheek science fiction shooter based on Ken Silverman's technologically similar Build engine, id Software had nearly finished Quake, its next-generation game, which mirrored Dooms success for the remainder of the 1990s and significantly reduced interest in its predecessor.

Duke Nukem 3D is a first-person shooter computer game developed by 3D Realms and published by GT Interactive Software.

It is a sequel to the platform games Duke Nukem and Duke Nukem II published by Apogee.

Duke Nukem 3D features the adventures of the titular macho Duke Nukem ( voiced by Jon St. John ), who fights against an alien invasion on Earth.

Along with Wolfenstein 3D and Doom, Duke Nukem 3D is considered responsible for popularizing first-person shooters.

After fifteen years in development hell, a direct sequel was released called Duke Nukem Forever.

As a first-person shooter, the gameplay of Duke Nukem 3D involves moving through levels presented from the protagonist's point of view, shooting enemies on the way.

The environment of Duke Nukem 3D is highly destructible and interactive ; most props can be destroyed by the player.

Duke Nukem 3D features multiplayer.

Duke Nukem 3D did not support the TCP / IP client / server model, instead basing its network play on the IPX LAN, modem or serial cable.

Duke Nukem 3D players often either battled modem-to-modem, using the IPX network utility Kali or the Total Entertainment Network ( TEN ) online pay service.

Duke Nukem 3D has been ported to run on modern Microsoft Windows variants including Windows XP and Windows 7.

Duke Nukem 3D is set on Earth " sometime in the early 21st century ".

The levels of Duke Nukem 3D take the player outdoors and indoors through rendered street scenes, military bases, deserts, a flooded city, space stations, moon bases and a Japanese restaurant.

The introduction establishes that the game picks up right after the events of Duke Nukem II, with Duke returning to Earth in his space cruiser.

Various spin-offs and modifications to the original Duke Nukem 3D were produced in the following years of the game's initial launch.

* Plutonium PAK / Atomic Edition: The Atomic Edition of Duke Nukem 3D was released in November 1996, and contained the original 3 episode game as well as a new eleven-level fourth episode.

The Plutonium PAK was also released as an upgrade package to convert the original release of Duke Nukem 3D ( v1. 3d ) to the new Atomic Edition ( v1. 4, later patched to v1. 5 ).

The Total Entertainment Network featured hundreds of Duke 3D players online at any given time and players had to pay a monthly fee.

The last major game to make use of the Duke Nukem 3D source code was TNT Team's WWII GI in 1999.

Its programmer, Matthew Saettler, obtained permission from 3D Realms to expand the gameplay enhancements done on WWII GI to Duke Nukem 3D.

Wiederhold was later hired by 3D Realms to work on the sequel Duke Nukem Forever.

The add-on was unofficial but was included in an official compilation called Duke Nukem: Kill-A-Ton Collection through business deals with 3D Realms.

Duke Nukem 3D ( Sega Genesis ) was released in 1998 by Tec Toy.

The same engine was used to power the Sega Saturn versions of Duke Nukem 3D and Quake.

The Saturn port used Lobotomy's own Slavedriver engine ( the same engine that powers the Saturn ports of Duke Nukem 3D and Powerslave ) instead of the original Quake engine.

He wrote to the Duke of Tuscany that " he planet Saturn is not alone, but is composed of three, which almost touch one another and never move nor change with respect to one another.

In a few months the Duke was to be the center of a controversy of some significance on the touchy question of the Protestant Succession.

A few days after this Englishman appeared, Defoe reported to Oxford that Steele was expected to move in Parliament that the Duke be called over ; ;

In 1256, the castrum of Abensprech was first mentioned, and on 12 June 1348, Ludwig, Margrave of Brandenburg, and his brother, Stephen, Duke of Bavaria, raised Abensberg to the status of a city, giving it the right to operate lower courts, enclose itself with a wall and hold markets.

The last Lord of Abensberg, Nicholas, supposedly named after his godfather, Nicholas of Kues, a Catholic cardinal, was murdered in 1485 by Christopher, a Duke of Bavaria-Munich.

Henry, Duke of Brunswick-Wolfenbüttel, then took command of the troops of the league, and after Albert had been placed under the imperial ban in December 1553 he was defeated by Duke Henry, and compelled to flee to France.

Albert the Bear (; c. 1100 – 18 November 1170 ) was the first Margrave of Brandenburg ( as Albert I ) from 1157 to his death and was briefly Duke of Saxony between 1138 and 1142.

Albert was the only son of Otto, Count of Ballenstedt, and Eilika, daughter of Magnus Billung, Duke of Saxony.

Albert was a loyal vassal of his relation, Lothar I, Duke of Saxony, from whom, about 1123, he received the Margraviate of Lusatia, to the east ; after Lothar became King of the Germans, he accompanied him on a disastrous expedition to Bohemia in 1126, when he suffered a short imprisonment.

In 1158 a feud with Henry's son, Henry the Lion, Duke of Saxony, was interrupted by a pilgrimage to the Holy Land.

Because Albert was a member of the Brandenburg-Ansbach branch of the House of Hohenzollern, it had been hoped that his election as Grand Master would reverse the decline of the Teutonic Knights since 1410 ; Duke Frederick of Saxony of the House of Wettin had been elected for the same reason.

His mother was Sophia, daughter of Casimir IV Jagiellon, Grand Duke of Lithuania and King of Poland, and his wife Elisabeth of Austria.

Albert was chosen as his successor early in 1511 in the hope that his relationship to his maternal uncle, Sigismund I the Old, Grand Duke of Lithuania and King of Poland, would facilitate a settlement of the disputes over eastern Prussia, which had been held by the Order under Polish suzerainty since the Second Peace of Thorn ( 1466 ).

Afonso de Albuquerque ( or archaically spelt as Aphonso d ' Albuquerque and also spelt as Alfonso, and Alphonso ; ; 1453December 16, 1515 ), 1st Duke of Goa, was a Portuguese fidalgo, or nobleman, an admiral whose military and administrative activities as second governor of Portuguese India conquered and established the Portuguese colonial empire in the Indian Ocean.

Ealdred supported Harold as king, but when Harold was defeated at the Battle of Hastings, Ealdred backed Edgar the Ætheling and then endorsed King William the Conqueror, the Duke of Normandy and a distant relative of King Edward's.

Alexander (; ) ( 5 August 1461 – 19 August 1506 ) of the House of Jagiellon was the Grand Duke of Lithuania and later also King of Poland.

He was elected Grand Duke of Lithuania on the death of his father ( 1492 ), and King of Poland on the death of his brother John I Albert ( 1501 ).

For want of funds, Alexander was unable to resist the Grand Master of the Teutonic Knights or prevent Grand Duke of Muscovy Ivan III from ravaging Grand Duchy of Lithuania with the Tatars.

The most the Grand Duke of Lithuania could do was to garrison Smolensk and other strongholds and employ his wife Helena, the Tsar's daughter, to mediate a truce between his father-in-law and himself after the disastrous Battle of Vedrosha ( 1500 ).

Great solicitude was devoted to the education of Nicolas as tsarevich, whereas Alexander received only the training of an ordinary Grand Duke of that period.

By the age of twenty, Ferdinando I, Duke of Mantua, began commissioning works from him, and he was also employed by local jewelers for figurative designs.

Thus the possibility of re-incorporating Portugal ( up to then Southern Galicia ) into a Kingdom of Portugal and Galicia as before was eliminated and Afonso became sole ruler ( Duke of Portugal ) after demands for independence from the county's church and nobles.

Alfonso was the son of Queen Isabella II of Spain, and allegedly, of her husband and King Consort, Francis, Duke of Cádiz.

Finally Amadeus of Savoy, Duke of Ostia, was elected by Parliament as new King of Spain.
