Age of Empires IV: Anniversary Edition

Create a custom Skirmish game with the following settings:
Teams: 1v1
Enemy Team: Easy
Generated Map: Dry Arabia or any other land map
Starting Age: Age I
Map State: Revealed
Starting Resources: Highest (Max)
Civilisation: Holy Roman Empire (Enemy doesn't matter)

Once loaded into the game select all your villagers and build 6-8 Barracks.
Let the Barracks produce simple Spearman until you have around 25 of them ready.
Now head straight into the enemy base and start destroying buildings and units of the AI.
Pressing F1 to select all Barracks and then setting a Rally Point right into the enemy base for all Barracks will make it easier to get a constant flow of new units where we want them, so do that and queue up Spearman in each building.
It should be no issue to win the game in under 5 minutes with the original 25 Spearman but this will make it even faster/easier.
