Alright, I have just finished playing the campaign again and this time was on Hard, this is my walkthrough if anyone is interested
Chapter 1: no need to talk about it, you can do everything normal, the executors are good tankers mixed with the heroes, keep them up front to take all the damage and when you want to get rid of the Golden Guard let your units attack the orc commander and his troops alone and pull back the heroes. If any of them survived, finish them off with Gardon and Merlon their health will be greatly reduced by the attack so its an easy job.
Chapter 2: I started with stacking towers at all entrances with a mix of cannon, guard and arcane, then I finished off the Pitlord first with a battalion of knights accompanied by the heroes and three catapults. I kept luring some units away from the bulk of his defense until I finished them off all and overwhelmed the Pitlord. I attacked with all my forces on the first demon base, I used the same tactic but this time I lured all of the units outside the base and killed them then destroyed the towers at the entrance and focused on the gates - I had 4 priests just for healing-. The murloc village is easy to deal with with any tactic you use, then attacked with the same units I used on the pitlord to march on to the demon gate to the north. The main base is a bit hard, I stacked cannon towers near it then lured the defenders to them to die - I used that for a silly reason because I don't want to finish the campaign fast because its great- then destroyed the gates with all of my forces. I used a lot of knights and crossbowmen with 2 or 3 greywolves.
Chapter 3: I gotta say it took a lot of time but I cleared the pass using catapults, crossbowmen and a few executors. The orange base is weak , use Gardon and Cora to help destroy it fast. then I marched to the two northern bases with 3 catapults, heroes and a lot of executors. The pink base was a pain because I didn't want to kill any of his units or buildings I just wanted to kill the mercenaries, I neglected any pinks in my way till I reached the commander and killed her. The dark green base I waited for pink to attack them to lure all units and again I used executors and catapults to destroy them. Defending your base is easy seeing that the enemies attacks are very weak, towers and a small group of units can deal with any threat - I used 2 executors 2 priests 4 zealots and 3 crossbowmen-.
Chapter 4: this chapter is a pain in the neck but I like it, defend your base by stacking all kind of towers on all entrances, I used just shadow stalkers in the first tier of the city, I attacked blue first and used arcane towers ability to quickly deal with the shades there then clean up everything, the same technique with orange and purple, you have to deal with the towers and shades if you want to attack with just stalkers, that'swhy I built a lot of arcane towers to use reveal, the second tier is easy to deal with using 4 elites, Brian and executors.
Chapter 5: this chapter needs a lot of concentration cause the food limit is 60, I stacked towers at the Ironfist entrance and stationed Cora and Larine at the other entrance with their given troops just train 2 priests and station them there, the offensive part was as follows, I trained War golems from blue base, executors from orange and knights, one overseer and few bowmen from brown then attacked the base near Gardon's base - forgot its colour- then attacked grey base from two points with the units I trained to attack on the first base and Cora, Larine and the troops with them. After I got the destructors I sent the offensive force to get killed then built destructors from all bases and destroyed green first - all you have to do is destroy the production buildings and they'll become idle and friendly- ignore the units only kill ranged units and towers, yellow is easy with the destructors giving that the ranged units number is low. I repaired the trebuchets and used them to thin out dark green and finished it with destructors.
Chapter 6: Again stack towers first to defend your base but you also need to build frigates to protect your flank from yellow base to the west. The new ship helps a lot, I built seven of it and seven destructors and used the destructors to give line of sight to the ships to bombard the towers on the hill near the shipyards then destroyed yellow base, same technique with the remaining bases. It takes time but I consider it efficient.
That's how I played it, and last but not least a special thanks goes to Shar Dundred and Kasrkin for this wonderful campaign and I can't wait for the next update.
EDIT: I noticed that in Arkain world there are no goblins at all if memory serves I had hadn't seen any goblin laboratory or hut in all campaigns, was that intentional?
Approved
