UNIQUE UNIT - GAESATAE
The cost of training the elite units of Ambiorix is higher than that of a warrior, but combat power is added when fighting against stronger enemies and areas.
SPECIFIC AREAS - OPPIDUM
Oppidum is an area that is cheaper and can be built earlier than industrial areas. When completed, the "apprentice system" technology will be released. It is able to defend, performs its own long-range attacks, and receives a large amount of adjacent bonuses from quarrys and strategic resources.
