Age of Empires II: Definitive Edition (PC) - Achievement - The Go-Getter

Defeat the Hungarians before Subotai has arrived in the sixth Genghis Khan mission "Pax Mongolica".

Time is of the essence again in this achievement. In this video, I build a second Town Centre early on to boost Villager production and get resource production in order. You may also want to focus on upgrading and producing one or two specific units. In this video, I focus on using Mangodai. A few Trebuchets won't go amiss either.
If you upgrade Mangonels to Onagers, then they will have the ability to destroy trees so it will be helpful to have one of these as I believe destroying trees will provide you with the best route to reach the structures that need destroying (2 x Castles and 2 x Town Centres).
Initially it appears the map is divided by a frozen river separating you from your foe and only one bridge connecting you, however if you follow the river all the way to the opposite of your starting end, you will see it has frozen over to the point in which you are able to cross, which leads to a wooded alcove with gold and stone. Using your Onager, you can destroy some of the trees and attack the Hungarian forces from the side. There is also a Castle and a Town Centre close to where you emerge in their base. All you need to do is use your siege units to destroy the buildings and protect them with your standing army as they push forward and eventually get to the remaining Castle and Town Centre. You also start with 10 x Saboteurs. 5 Saboteurs will destroy a Town Centre so remember to use these to your advantage as well.
