If going for impossible badge you can use this walkthrough as I'm using it and have found it very useful. At Zone 4 on Heroic no training fights although some battles you will require luck in Zones 1 & 2.
Fo captain Hunt for bio use Crystallize twice in skill ring at level 2 Disrupt at level2 twice in ring Reform at level2 twice in ring Leading strike and Break.
Try have high strength and vitality as you can.
When battle starts keep Captain crystallized kill him last and hammer on Sniper while removing his two many damage buffs.
When Sniper is dead beat the medic to death then the captain.
Heal when needed with yourself and veradux.
Also its not the end of the world if one of people dies(as long as its even numbers) as you can maintain the Captain crystallized to heal yourself if like me it ended in a 1v1.
To get political Assassination beat the Mayor on Challegening or Heroic.
To beat Baron drain his focus.

this is a good walkthrough of the game for herioc using a biological. It is what I'm using and so far I've just got to the Baron but trust me don't worry if you lose a few times some fights take way too much luck in them.
For Humans don't use arch angel for last boss incase you don't already know use angels and dragons it will take longer but you have to.
Limlekhong that is a Super/Revenge wave you need to be ready for it with a wall of hobbits and protectors or whatever tank you have to block the wave while your mages destroy it.
The game is quite easy and there's even a walkthrough for it if your stuck and all the caves are fairly easy if you have patience.
But trust me you need to finish the game a few times first to get most of the spells.
I think the game is fairly good the game kinda takes notions sometimes with bridges.
As sometimes you could be using proper bridge making and it sill colapses or to get it done sometimes seems you need nearly all your budget.
