Age of Empires II: Definitive Edition (PC) - Achievement - No Wonder You Won
Win the game before Mahipala completes his Wonder in "Sacred Waters".
This achievement triggers upon completion of the level.
If you ignore the secondary objectives and take the quickest route, it's very achievable with time to spare. You would be pressed for time if you go around the map completing side-missions. This isn't recommended.
Push forward with your initial army to Kalinga (Teal) and bring your navy along the coast to clear the enemy boats. As you try and breach the city, the troops will push you. When they all die, some of the city buildings come under your control and the remaining buildings become friendly.
With the city under control, upgrade your troops and build as much as you can as quickly as you can. When you leave the city, you lose control of the buildings shortly after, so make sure to at least get your upgrades in. Friendly boats will also appear, which you can bring to your Dock for resources whilst it's still under your control.
Push forward to the closest market. Once destroyed, move to the one in the North-East. This will take you along a route in the trees, where at the end of the pass, you discover some Trebuchets. Note that these Trebuchets have limited usage, so will not do much more than take down the nearby enemy Castle. Once the Castle is taken care of, move into the city and clear out the remaining troops to bring it under your control. Reinforce your army if needed, but remember that time is of the essence, so don't leave it too long to move out.
Meet up with your ally, General Araiyan (Orange) to take control of his forces, ready for the final push. Target the Castles with your Siege Elephants and keep them protected with your remaining troops. Do your best to keep your heroes alive and fighting throughout to increase troop morale.
