First about the entire campaign
The difficulty is hard even if i only played on normal (and 2 missions on easy) and sometimes ridicilous but in most cases (not all) balanced.
Many different and unique units are very interesting and give the player different strategies even if the best strategy in many cases seems to be playing the turtle.
The heroes are also interesting to play and have well written stories (even if i don't really like some decissions). Also van Durce became my favorite hero because his chararacter is much more interesting than he is presented. However his skill are way to passive in my opinion.
Another thing i really like is the Leadership you can chose but the implementation is not perfect since it required restarts in many cases because i wanted to read it. The enemy often just attacks to early with too many troops to read it.
Now let's start with the missions
Mission 1 The Bootlicker
We see a new charakter: Zed. It's interesting to play with this summoned unit in many cases but it seems that he is forced to be mentioned in so many dialogs. Also i liked it to get rid of the Golden Guard Soldiers ^^
And it is a map without a base making it easier than others.
MVU: hard to say but i chose Gardon
Mission 2 Dark Blades
The demons are here! Since i already played the beta version of the campaign i focused the hidden Demon Gate and had nearly no problems clearing the map. Most demons only came from the south western part of the map so it was nice to play it.
MVU: Cleric (Great support)
Mission 3 Rebellion
This is my favorite mission in the campaign because the enemy has nearly no OP-Units but many weak peasants.
One feature was that the peasants used the Archs to port to a certain point so i could keep them away using many towers and some Executioners to prevent them from dealing too much damage to the towers.
A little problem was that Retka had barracks in the villages so that his troops disturbed my attacks upon the village with the Marauders.
MVU: Watchtower
Mission 4 Lord of Shadows
I liked Brian's Shadow Creatures because they brought a stealth aspect to the map. Somehow i missed the shade near the trebuchets.
At least it was possible to play toghether with a useful ally (Until the major got killed)
Something i disliked at the plot here was that the Undeads have again everything planned perfectly and that they have Plot-Skills (Port Gardon away; One-Shot Salomar in the Intro of the campaign) --> I am no fan of plot-skills
But this map had good balance and Zed was a good defender (i didn't used him to attack because i wanted him to stay alive)
MVU: Shadow Stalker
Mission 5 End of an Uprising
Yes this map was a bit harder but not impossible even if i lost some buildings in the main base. It was interesting to play 3 player slots which could be specialised to specific roles (E.g. i used the Golden Guard as support units because of their leadership bonus)
The trebuchets are difficult to rate: on the one hand they are op but on the other hand they prevent the mission from beeing ridicilous long.
About Retka: I killed his base with trebuchets and destructors and wanted to execute him with a small force: Vampire-Aura is quite nasty.
About Imperator: I killed Retka and Scarlett gave up (nice option) so i could kill the templars with the entire force --> It was more interesting than using destructors like i did it in the beta but he died quite fast ^^
A problem here was that i got nearly no possiblity to build another base so most of the time i played a turtle and a attacking group to clear the city.
MVU: Trebuchet !!
Mission 6 Burning Forest
In the beta i didn't finished this map because there i haven't seen how op the Terror-Class-Ships are. With them i killed all factions except the Elven Main Base and the Dark Elf Base so this map wasn't too hard but still interesting. A problem i see here is that Merlon's Leadership bonus seemed quite useless to me because terror ships are the only ships you really need.
MVU: Terror
Mission 7 Long Live the Queen
The Queen is dead - long live the queen.
In this map i had some moments where i thought "Shar Dundred could be quite ok". There were many enemies but since the half army of the Golden Guard started a rebellion (Meh ... it is way to hard to keep them alive) and Sapphira supported me with Frost-Wyrms it was very nice to play. (Honestly i didn't trusted Aridon to be dead - i hoped so but as the end shows he as not dead --> He makes way too few mistakes in my opinion but i doesn't prevent the story from beeing interesting)
The Assassins of the queen were more anyoing than a real danger so Walkyries and Dragon Hawks (and Frost Wyrms) could easily kill them.
MVU: Knights of Kome
Mission 8 Burning Corruption Away
Finally another mission without a base where it was possible to explore the map (and got f**ked by Demons).
It was interesting to have here another decision even if it was possible to see that the Fire Spirits were the "good" guys. (if you can speek of good guys in Arkain)
And Progaderas died another time.
So here is nothing much to mention.
MVU: I would say Harmos
Mission 9 Lords of the Golden Guard
Well this mission was of the kind that throws and anvil in your face.
We have an ally - i like it - but this ally can easiliy be killed by the stupid Dragons and is no real threat to the enemy. I only kept him alive because i didn't wanted to have the Dragons in my base. Speaking about the base: Why the heck are there 6 Demon Lords with quite bad loot in the woods. This shouldn't be anything a Demon LORD should do.
And also the orcs were attacking with an interesting group of different units. (I am interested to see how they organised this creepy group of units)
The demons were ... ok ... but what really killed my nerves where the Knights. The enemy has OP-Units but i have only the Golden Guard and the Units together were not that strong as the Ironfist.
Also at the beginning the strategy was again to play the turtle while harvesting wood to get Destructors (and to kill Demons and Orcs with them)
Here was the only time i really used WhosYourDaddy 1 time.
MVU: Destructor
Mission 10 Menace Below
Speaking of an anvil in my face. Here came the second anvil. Why do the dwarves have to be surrounded by enemies again (like in the first human book). At the beginning it seemed that there would be a choice about who will play together with the dwarves but i was surprised that the King has chosen to help the Golden Guard.
I tried it on normal but there are just too many kobolds (or i failed clearing early enough)
Then i played on easy where it nearly became way too easy but i should mention that i played quite aggressive on this easy difficulty.
Wouhou let's kill Progaderas again.
MVU: Rune Priest (or were they called Battle Priest?)
Mission 11B End of the Ironfist
Yes i have chosen van Durce because he became very sympathetic in the interlude.
There were many enemies to fight but it was good balanced because you had 2 allies and got a group of Airships from Marin that could be used to kill Merlon and the Knights of Kome when their armies where busied and the Elven and Royal army because they couldn't attack my airships within the forest.
And van Durce had to kill his nephew

MVU: Pride of Humanity
Mission 12B Purification
The third time we play on this map and this is the ultimate turtle-map. (The next anvil comes in)
3 Factions to kill each spamming units as heck and they kill each other only sometimes.
The Dominion was the easiest (and funiest) faction to kill because i could use my Destructors. (Shot the fortress --> run away --> shot again --> wait i got attacked --> look to the Destructors --> F. you Brocktar)
The Demons unfortunately had Nether Drakes so i had to wait.
A good point was that the other factions adapted to missing enemies which kept the difficulty at a certain level.
Finally only the Undead where remaining so i thought: Let's kill them in the open field.
But no - They are just imba so i had to wait for the Purificator (Sorry but this is bad map design because it only makes the map longer but without making it interesting since i could easily keep the Undead dead)
MVU: Paladin
My strategy was to use heros and Paladins to keep enemies away and some Crossbowmen to shot from behind.
Another thing on this map/ before it: 3 Lichs talking about "balance" if i remember correctly --> Again the stupid OP-Undead (or old gods?) having everything under control
Mission 13 The Red Night
No base! I like it. (Even if it was challenging)
There is not much to say about gameplay but about the story.
Volarian is no Tyrant?! (Why changing between first and third person from storytelling

)
If i do a second run on these campaigns (then only on easy) i don't take any demon-eye.
Yey artifacts corrupted with the essence of a demonic bitch...
At least the other hero got the Slavemaster-Soundset (for me it is still Kobayashi of Shards of Resistance)
MVU: Adaele
Mission 14B The Golden Crusade
I tried it on normal but when i ran out of Gold and had no fleet i sayed: "Forget it. It takes too long doing it on normal" so i switched to easy where my ally's AI got broken and he didn't sent any troops.
Using Oil as gold is interesting but the way you have to get it here is just ridicilous because the enemy can spam ships as heck so it became too stupid for me. (on easy it became possible)
Mostly this map's content was: Building battleships - we need more battleships - hey could we have some more battleships. Oh and you need Pegasie (i don't know if this is the plural) to kill Terror-Class-Ships
MVU: Battleship!!!
About the difficulty: a problem i see is: that normal difficulty is much much harder than easy (the gap is way to big) which says "lol you noob try this"
Then i have seen the end of this campagins.
The Golden Guard was the target of a Plot-Skill!!! So it seems that it doesn't matter if you chose to play Golden Guard or Ironfist. (Maybe i'll find out)
Adaele seems to have died and here body got recyceled by Lisara.
Oh and Aridon is not dead what a biiiiiiiiiiiiiiiiiiig surprise and he does what he do best: tricking the mortals and recycle them.
Largoth replaced the Emperor and Gods manipulating the story: i just say meh.
Arkain is only the name of the continent? ok - i thought the planet/ world has this name but ok.
