Our research shows that there are three main theories of what the Trojan Horse might actually have been, so we are representing three kinds of Trojan Horse in the game. One theory is that the Trojan Horse may actually have been an earthquake, because the horse is a symbol of Poseidon. Poseidon is the god of the sea and the lord of earthquakes. He really, really hates Troy in the Iliad.
Archaeological research also shows that at a certain point when Troy was under siege, there might have been an earthquake, because signs of violence coincide with piles of rubble that an earthquake may have left. What this means in the game is that events will happen every so often in which an earthquake hits Troy. Buildings are damaged, the garrison is severely depleted, and you get a different battle map of Troy, where there are breaches in the walls.
It’s much easier to take the city then. So if your aim is to capture Troy, you need to look for these windows of opportunity, and if you’re one of the factions that wants to defend the city, you need to be extremely careful when the earthquake strikes. You need to send help to the city, if it’s threatened in any way.
