This guide will show all or at least most info you might need for defeating the campaign on easy,normal, hard, hell or epic difficulty.Thanks go out to ZoharMasni at Ravenmarch for giving the detailed information.

Easy and normal difficulty:
Attachment 407
*red circle = start
*yellow circle = quests that needs to be done
*blue circle = waiting point (which is different at hard + )
*black square = dont attack unless NPC's from Nirwad barracks pass
*green circle = exit ; finish
*white arrows = path pointers

Steps:
1.Go to 1st "yellow circle" and when u defeat it , it will ask u to who to give egg.Choose Essel. -> Essel is located at Essel Barracks which is in picture 3rd "yellow circle".
2.After u gave egg to Essel , head to "blue circle" and after u defeat it wait till NPC's from Nirward Barracks pass the 2nd "yellow circle" then attack it.
*Its important that u avoid every NPC (convoy fights ; When u gave the egg to lets say Essel for example other Barracks [Sawyer , Nirwad , Jeasson] will send their convoys[NPC] to go after the one that holds egg in this case its Essel).
So its improtant that u wait till they pass , dont attack them nor attack while they are attacking (under fire).
3.After u defeated 2nd "yellow circle" it will be "Enter Battle" (Event ; Quest) and u need to defeat it (forgot why , something about hostage ; Use one general for it since its easy).
4.Head with rest generals to 3rd "yellow circle" and avoid every NPC's (convoys).
*Since we are giving egg to Essel all the rest NPC's from other barracks will send troops to Essel to fight him ; and u must avoid that NPC's since they are 100lvls and will 1shot u with their tactic attack and they have 10 000 HP.
5. So u need to wait till all NPC's (convoys) pass and then attack , dont attack if its underfire since they are in there also.
*Once more , dont forget that NPC's from Nirwad , Sawyer and Jeasson will troops to Essel so u must avoid them , never fight these convoys.
6.After u defeated 3rd "yellow circle" u took egg back , so u can go to exit now "green circle" and thats it.Its that simple.
*Remmber that in these barracks where u need to re-take egg its always stronger NPCS then usual ones ur fighting ;


Hard difficulty:
Attachment 408
*red circle = start
*yellow circle = quests that needs to be done
*green circle = exit ; finish
*white arrows = path pointers
*blue square = where u might drop some phantoms

Steps:
1.Go to 1st "yellow circle" after u defeat it, give egg to Sawyer. Sawyer is located at 4th "yellow circle" on picture.
*When u enter 1st "yellow circle dont go further until u give egg since in next territory there will be more NPC's if u enter before giving egg.
2.After u gave egg to Sawyer head to 2nd "yellow circle" avoid NPC's (convoys) never fight them , no matter what.
3.After u defeated 2nd "yellow circle" head to 3rd "yellow circle" (ludovic picture if i remmber correctly).
4.When u defeated and finished 3rd "yellow circle" head to the 4th "yellow circle" aka Sawyer Barracks (the place where u gave egg to).
5.After u defeated 4th "yellow circle" u gained egg back , and now u can head to the "green circle" = exit; finish
6.Thats it , u might drop some phantoms where u feel like it , or wheres alot NPC's so u can rush skip to next.
7.Its simple when u give egg to right person and avoid NPC's (convoys)
**Theres no specific spot to drop phantoms , so enter with 1general drop 2phantoms (in territory wheres only 1NPC so u can rush forward).
**At "blue square" u might drop some phantoms to rush forward to "green circle".


Hell difficulty:
Attachment 409
*red circle = start
*yellow circle = quests that needs to be done
*green circle = exit ; finish
*white arrows = path pointers

Steps:
*Its almost the same as Hard so i wont be giving much steps into this one , so please read Hard guide to understand it better;
1.Go to 1st "yellow circle" after u defeated it give egg to Jeasson. Jeasson is located at 4th "yellow circle.
*dont enter next territroy untill u give egg , since it will contain more npcs. (read hard guide to understand it better).
2.After u gave egg to Jeasson head to 2nd "yellow circle" (this 2nd yellow circle is always "Enter Battle" (event ;quest) so read Easy/Normal guide to understand it).
3.After u defeated 2nd "yellow circle" head to 3rd "yellow circle".
4.After u defeated 3rd"yellow circle head to 4th "yellow circle"
5.After u defeated 4th "yellow circle" and gained egg back , head to "green circle" exit;finish.
**Read Easy/Normal and Hard guide to understand better some things , its mostly the same but only different person ur giving egg to ; so its only the path that is different abit.
**Read Hard guide its same as phantom drops on Hell.


Epic difficulty:
Attachment 410
*red circle = start
*yellow circle =quests that needs to be done
*blue circle = quest that i skipped , dont know if it would be easier if i did it.
*green circle = exit; finish
*black circle = dont enter at some point read guide/steps.

Steps:
1.Go to 1st "yellow circle" and duel em out.
2.After u defeated it give egg to Jeasson.
*Dont enter 1st "black circle" untill u gave egg to Jeasson and untill NPC's(convoys) from Nirwad barracks get to 2nd "black circle".Cos it will contain many NPC's (15+ instead 5-6 only).
3.After u did all that , go to 2nd "yellow circle" and do the quest like on every other difficulty.
4.Head to the 3rd "yellow circle" ... when u defeat it , it might send some convoys(weaker ones) at 2nd black circle so it could be good idea if u dropped phatnoms there at start 1-2 only.
5.After u did 3rd "yellow circle" head to 4th "yellow circle" (need to take egg back).
6.After u took egg back , head to exit "green circle"
7.Thats it.
**1st "blue circle" i skipped that quest , it will show up later i think after 3rd quest done.Dont know if it would be easier if i did it , but still u can skip it.
***I recommend reading every guide(difficulty) then doing specific one , cos i might forgot to mention it in hard for example but i did in epic.***


If you have any other strategy that works better on a certain difficulty feel free to post it here!
