NOTE: Achievements pop upon starting the game if you've already earned them in the 2018 version of Age of Empires
In this world, you can earn all achievements except for the win with wonder, ruins and artefacts, and the win a ranked match. All the others work! Credit to FGNZ DEBROIN for making the first version of this scenario!
First, download the scenario here:
https://www.dropbox.com/s/kxvbggz6iiv3s2g/ACHIEVEMENT%20WORL...Copy the file to the desktop.
Now in Age of empires, go to editors->Campaign editors->Open Scenario folder.
A folder will open, copy the file you copied to the desktop to this folder. Now back out and reboot the game. It is a bit glitchy, but after one or multiple attempts, the file should be visible in the list of scenarios in the campaign editor (ACHIEVEMENT WORLD TRUEACHIEVEMENTS).
Now select this scenario and click 'Add scenario'. Now at the top of the page give your campaign a name and now select 'make campaign'. Now go back to menu and select campaign, and go to custom campaign.
Start your freshly created campaign and start it on easy.
Upon starting, select ENTER on your keyboard and type in
STEROIDS and select enter again.
Now click on the town center and advantage 3 times, all the way to the iron age.
Upon winning the match that should pop you:
Next, start assigning villagers to gather:
-Wood (from trees)
-Food (from farms, bushes with berries and animals)
- Gold (from the large and few smaller mine locations)
- Stone (from the large and few smaller mine locations)
This will start you getting progress towards:
Note that also these achievements don't pop until you finish the game.
The food one is probably the hardest one and will take multiple games.
Now while your villagers are gathering resources, you can start researching all of the technologies (which will speed the resource gathering up also and you can kill the medusa and heroes in the East)
Start with the latter. Select one of the many race cars and let them perform the ground attack move on the area where the heroes are trapped (note: I could only do this with left mouse click)
Now start researching all the technologies. There are 10 buildings which require technologies to be researched. For the buildings that build fighters (docks, stable, barracks, archery, siege workshop), it are almost always just the options on the middle row. For others it can be all options. Please note that you need to go through the buildings multiple times as researches unlocked in the market and government building, for example, will open up new technologies.
THIS ACHIEVEMENT WILL POP IN GAME, SO KEEP RESEARCHING UNTIL IT POPS!
Now there are ruins and artefacts on the right-hand side, and besides, you can build a wonder. However, I could not get these to pop in the campaign and thus you will need to go for them in a custom game.
I hope this was helpful
