|—Age of Empires II description|
The Organ Gun is the first unique unit of the Portuguese in Age of Empires II HD: The African Kingdoms. It is a gunpowder siege weapon that fires a volley of bullets. Like all other unique gunpowder units, Organ Guns do not require Chemistry in order to be trained.
Organ Guns can be upgraded to Elite Organ Guns in the Imperial Age.
The Organ Gun is one of only four unique siege units in the game (the others being the Ballista Elephant, the Hussite Wagon, and the Houfnice). It fires a volley of five bullets in a spread pattern that can hit multiple enemies. It is more effective against large groups of units, because other than the one main bullet dealing the panel attack, the other four bullets deal effectively only attack. Conversely, however, it is woefully ineffective against structures, in a similar vein to the Scorpion, dealing very light damage to them, even when used in large groups.
It is advised to always protect Organ Guns, because their subpar accuracy (without Arquebus) and slow Rate of Fire leaves them vulnerable, especially to melee attacks. Firing from behind allied units and buildings can prevent incoming enemies from exploiting the Organ Gun's minimum range. Halberdiers and Hand Cannoneers pair well with Organ Guns, and can effectively protect them from melee attacks. They are also vulnerable against enemy Bombard Cannons and Siege Onagers, though Elite Organ Guns can barely survive a hit from a regular Onager. Also, despite having an attack bonus against rams, they are a poor choice against them, while the Rams can deal devastating damage to an Organ Gun, if ordered to attack it.

An organ gun, most commonly known as a ribauldequin or rabauld, was a Renaissance-era volley gun with many small-caliber iron barrels set up parallel on a wooden platform, in use during the 14th and 15th centuries. When the gun fired in a volley, it created a shower of iron shot, serving mostly as an anti-personnel gun. The name "organ gun" referred to the artillery's resemblance to a pipe organ, a well-known musical instrument.
