Celts
Infantry and Siege Civilization
Unique Unit: Woad Raider (fast infantry)
Unique Technology: Furor Celtica (+50% hp on Siege Units)
Team Bonus: Siege Workshops 20% Faster
Extras: Infantry and lumberjacks 15% faster, Siege Weapons fire 20% faster, and Sheep not converted if in Celt's LOS
Notes: Your going to be disapointed with the fact that they can only reasearch 2 technologys from their blacksmith in Imperial age, your only able to build blast furnace and Plate Mail armor. You are able to build every siege unit except bombard cannons. Overall, you should build a lot of infantry to protect your powerful siege units.
Recommendation? No, Not unless you are fighting a big infantry civilization or the Byzatines. They are great against Byzatines.
