Age of Empires II: Definitive Edition

Get all upgrades. To be safe I built 3-4 watch towers around all TCs as soon I had enough stone. Allied TCs are attacked after four stables (orange) are destroyed. Send troops to 3 TCs immediately. You can kill some of ur own villagers to make more troops (I didn't have to).

Keep as many of your cavalry as you can alive from 1st phase (you can leave one archer behind to distract red camels before the wall). Then send them immediately to orange base and snipe villagers (4 are around tower, 4 more at granary) and one TC. After that he will make villagers from distant TC and send them to build a wall - you can easely kill them there with Pyrrhus. Orange will spam cavalry, so you can start to destroy the stables. As fast as you can, make hoplites in your base and help your little army. I sent also one villager to build 2nd Academy nearby. Without economy Orange's cavalry spam will end eventualy, and I was able to destroy all 6 stables around 14:30.
At this point only red was sending his camels toward purple base (easy to deal with few academies there), and units of blue bugged ¯\_(ツ)_/¯, so 10 minutes passed quite peacefully.

Made on hard diff. Inspiration here:

Soon as you gain Villagers, I set them to defensive resource collecting. Then built walls/gates/towers around Allies Town centres.

Whilst this was happening I built an army of stone throwers and archers (set on defensive to protect stone throwers)

You will see there are gaps between walls and cliffs along the map, I just built a wall in between every gap across the map and just kept adding sentry towers.

Once all walls are built send army to crush orange stables.

I waited the 10 minutes I weren't attacked for the 10 minutes, (maybe luck a one off)
