AoE2 HD Expansions - 1v3 Hardest AI in RM Arabia
I recommend watching the video with 2x speed, makes it much easier to watch due to my limited gameplay pace.
Took pretty many tries to figure out how to do it. Tried many different civs, strategies etc. First time I succeeded winning against 3 hardest bots alone.
It is not pretty, but I managed to win. Im crap at the game still, I know.
