Building the siege workshop in Age of Empires 2: Return of Rome
In order to build the siege workshop you need to build at least one Archery Range and reach the Bronze Age.
In the siege workshop you can make catapults and ballistas, and eventually upgrade them into heavy catapults and helepolish, which of course are better.
Useful upgrades for these units are to be found in the Government Center: Alchemy, Ballistics and Engineering.
Remember that to unlock the Heavy Catapult you need to research the Siegecraft in the market, and to unlock the Helepolis you need to research the Craftmanship, in the market as well.
Not all civilizations support those upgrades though.
The best civilizations for siege units are:
- Sumerians, whose catapults fire 30% faster
- Hittites, whose capults have 50% more hitpoints
- Macedonians, whose siege units cost 25% less
