Worshipper – “Betrayal” [2nd campaign, 1st mission]

Elysium, I don't know what your problem is... For example, I initially had trouble finding the entrance to the dungeon. But since you've already found it, try recruiting a couple of Cerberus and Hellhound units along the way. You can recruit more in the dungeon if you've gathered a few piles of gold, and some will join you automatically. Attacking neutral creatures from Inferno is pointless – it's a waste of your army. And, if possible, a screenshot of the initial setup of your and the enemy's troops in the final battle – maybe we can suggest how to defeat them better :)
