custom campaign BadHuman GoodOrcs ideas:

[Lagi7]

Mission 1
orcs slave need to build 6 human houses
player dont have any combat units, just town hall
and orc peons can build only human-farms
area is surrounded with blue footmans

twist:
after mission start a red footman will come and say:
"You ugly mf. Cant look at your foul faces. That suppose to be human house?! You cannot even keep straight plum!"
and will start killing peons

and player cannot do anything about that
he can only to train peons faster and hope to finish 6x farms, before red footman kill all peons

twist2:
there is not enough gold in gold mine, so after 1st gold mine collapse.
player need to send peons away, but this trigger blue footmans
"hey where are you going!"
and they will start chasing and attacking peons that go away from town hall.
this should make player super angry to eradicate all humans from digital azeroth in next missions

there is caravan of human peasants with goods, you need to kill them, they drop resource that you need to pick up and bring back to your base

[Lagi7]

mission that you do only with Necrolite and Warlock - you need to darkvision whats ahead, summon monsters, and Poison Cloud everything + plus summon skeletons as army
... i would define custom summons to not disappear so fast.

human killing orc ladies
and you need to save as many as possible

[Lagi7]

one smart orc will find out how to do magic to counter human empire power

[Lagi7]

you send expendition to the pink forest. where you capture wolfs (kill old wolfs and collect puppies into peons bag) and build kennels.

twist: if you dont kill any old wolf, you could use Healing Saliva upgrade in the next missions.

you can achieve it only by luring old wolf by one of your orc, who then die bite to death by wolfs. But neutral wolf will change map position thanks to that.

infiltration misssion

you have some units that can utilize invisibility and you need to capture catauplts in human fortress

sneaking in would be easy, harder would be to escape (because catapults are slow, big, and need to be reminded to hold fire)
