Age of Empires II: Definitive Edition (PC) - Achievement - No Royal Hair Touched
Reach the King before 10 minutes have elapsed in the second Gajah Mada mission "Unconditional Loyalty".
Time is of the essence again with this achievement and it's not the easiest thing in the world to reach the king with time to spare. Firstly, it should be noted that you have an ally to the top left of the map who will help you, but you will need to find him first, so it's best to send one of your scouts over there. It says in hints that you can command your ally which gate you would like them to attack using chat commands. I use '106' to instruct him to attack the middle gate in this video.
Secondly, there are local villagers and buildings that will join you when you find them scattered around which are crucial to have the economy you need early on. I miss a couple in the video, but get the essentials. If you want to get them all, you should resign at the start of the game and familiarise yourself with where everything is on the map - This brings me to the third starting tip. There is a decent sized army that will join you around the middle right of the map, so it's best to send your other starting scout towards them as soon as you can - especially as the army consists of elephants, so it takes a while for them to get back to your base.
I found elephants the best unit to produce to breach the outer gates of the wall quickly and get to the king, so if you choose to do this as well, it's best to build a few Stables, to pump them out quickly and focus on food and gold in the beginning. You can find a few houses around the map that will become yours when you find them, but you can also build a few yourself just to be safe and then you can focus less on wood and more on food and gold.
Once the gate is breached, the units in the city tend to push forward to you and spread out a little bit, which can give you an opportunity to send a few units in towards the king. Be careful if any Bombard Towers are still up though as you may need to dodge the cannonballs on the way there.
