add_army town nTownID, bUpgrade - Fills the town with all heroes. nTownID can be:

HEAVEN = 0
PRESERVE = 1
ACADEMY = 2
DUNGEON = 3
NECRO = 4
INFERNO = 5

bUpgrade 0 or 1, for example: add_army 5, 0

Oh, it's quite complicated. If this is working code, I've made a simplified version. Take a look and choose the hero who needs an army.
Let's create an improved army of Humans, 10,000 strong.
add_army 1 2 10000
The first number represents the Human army.
(1-Humans:smile17: :smile13:
2-Light Elves
3-Mages:smile16:
4-Dark Elves:smile41: :smile29:
5-Necromancers:smile24:
6-Demons:smile51:
7-Dwarves:smile47:
8-Orcs:smile19: )

The second number represents the upgrade level: 0 = not upgraded, 1 = upgraded, 2 = super-upgraded creatures.

The third number is the quantity. If it doesn't work for you, check if you entered the code correctly. If you did, I apologize; it works for me, and I'm running around with armies of 10,000 upgraded creatures.

And if you enter 9 for the army, it will be Elementals, Knights, and Phoenixes
