|“||Stronger than Scorpion. Light artillery that fires large arrowlike bolts.||”|
|—Age of Empires II description|
The Heavy Scorpion is a light siege unit in Age of Empires II that can be trained at the Siege Workshop once the Imperial Age is reached. The Heavy Scorpion fires large arrow-like bolts. It is effective against groups of enemy units as the bolts cause damage to multiple units in a straight line. Unlike the Mangonel line, they do not damage friendly units. This can make all the difference in a pitched close quarters battle.
The * indicates that the civilization can fully upgrade their Heavy Scorpions, i.e. gets Siege Engineers. Faith and Heresy are not taken into account because they only contribute to their combat strength in a very situational manner.
Heavy Scorpions are effective against slower units such as infantry, archers, and Monks, where its slower-moving bolts have maximum efficiency. Heavy Scorpions perform poorly against Woad Raiders, Eagle Warriors, Huskarls, and cavalry, which can dodge its missiles and close the gap quickly. Heavy Scorpions, like most siege units, should be well protected, as their slow speed makes them very vulnerable to attack. They are often paired with Halberdiers to deal with enemy cavalry. This combination is especially prominent with the Bulgarians, Celts, Chinese, Ethiopians, Khmer, Slavs, and Teutons, as all have either a civilization bonus or unique technology that benefit the strength of both.
When used properly, Heavy Scorpions can be quite devastating. A medium-sized group of Heavy Scorpions can decimate whole armies of infantry and archers in the blink of an eye, and even hold out well against cavalry in sufficient numbers. However, Heavy Scorpions are always vulnerable to longer ranged attacks such as that from Bombard Cannons. When maneuvered properly, Cavalry Archers, especially Mangudai can deal with Heavy Scorpions efficiently. Onagers are also very effective against Heavy Scorpions.

Dynasties of India
- With update 61321, Heavy Scorpions have 8 pierce armor.
- With update 61321, siege units and ships are now resistant to armor-ignoring attacks similarly to buildings.
- The Heavy Scorpion in The Age of Kings makes a 'whoosh' sound when it fires its projectile, which it also shares with the Galleon. In The Conquerors and after, the sound no longer occurs and it makes the same sound as the regular Scorpion due to the file being missing in The Conquerors' files.
- Interestingly enough, Heavy Scorpions have a 0 melee damage value, meaning that Rams and Siege Towers take extra damage from them due to having -3 and -2 melee armor respectively. On top of that, Heavy Scorpions also have an attack bonus against Rams.
- The Heavy Scorpion is based on the real-world Manuballista (also known as a Cheiroballista) which was an improvement to the existing Scorpio, being more portable and less resource-heavy.
- Despite it acting like a Scorpio, statistically and in-name, it is more of a Ballista.
- The Byzantines, despite being the only civilization that actually used the Scorpio during the majority of the Middle Ages (until the Crusades where it had a comeback), do not have access to the Heavy Scorpion.
