Hi, its me again. Just like when I finished your human campaign I now finished your undead campaign and will post my experience as well as the bugs and issues I found. And there are quite a bunch.
So once again I love the ideas you put in but it misses polish and playtesting, making it fun but flawed at times and the reason it is not on the same level as some of the other custom campaigns. However im sure you can improve these things so here are my thoughts and a score at the end:
1) In the first mission, the camera angle goes inside a crate
2) powerfull typo again, its called powerful
3) your secrets are the worst I've seen. They are extremely badly hidden with no indication so people either have to use iseedeadpeople or deforest the whole map, place something that indicates that there might be something but dont just place some dudes behind trees or at rivers at random.
On top of that there are in the Dalaran mission stat books and such that you cant get unless you cheese or ignore Antonidas. I find this design stupid and silly, if you kill Antonidas you win. If you ignore him and explore which breaks any immersion or sense you get rewarded. Big no. Either make Antonidas retreat so you can actually explore those areas or leave it be.
I had to play every mission with iseedeadpeople to check if I missed something as the campaign encourages this sadly.
4) The Pandaren Keg quest does not work. I went up with my Keg to him and he only tells me about the quest but no way to turn it in
5) Falric should get the special hero treatment. Enemy spells on him are annoying and last very long like Polymorph.
6) You get many items but few heroes, this time not all items are legendary like in the human campaign but it makes even more sense to turn Falric into a hero (or a semi-hero) or at least someone you can put the items to use, maybe dont make him a full hero but find a use for the items or make some combinable.
7) Falric scales extremely bad with his upgrades. If you upgrade him only his maximum attack damage increases but never his minimum - so with all upgrades he deals 35-115 damage. That doesn't feel right. He also becomes obsolete after halfway when you get the Dreadlord or the Lich pretty much.
8) The undead roaster is fun but overbloated, alot of units fulfill a purpose only in the mission they get introduced
9) In the Siege of Silvermoon on the ghost secret for Arthas there is a typo with a double ::
10) Banshee 50% revive upgrade are buggy. In the Siege of Dalaran each time they revived they decided to join the mage guilt and were hostile towards me.
11) Spirit Towers with all upgrades have more HP than armored ziggurats, though thats your design choice I just wanted to point that out
12) Arthas is OP and by the end has like 7k life and I love it. Finally he feels like an actual Death Knight and not like a bad Paladin copy but I would've loved it if he has anything Frostmourne related or kept his Chaos Damage to distinguish him further.
13) You should not go omega crazy with the books, you get really silly stuff like a tiny troll camp giving your hero overall 5 stats permanently, adjust it to what we face but once again your choice
Note about difficulty:
Three Moon Keys and Blackrock N Roll have been the hardest, though if you instantly rush east on Blackrock N Roll and make your base there while Arthas and Kel Thuzad solo the armies its not too hard. The final was extremely easy and I hope you'll add more waves and make all of them attack on the final 2-3 minutes so its truly a final battle. I was waiting around most of the time and it honestly annoys me the most on this.
My score:
Right now 7/10, its okay. If you fix the bugs I mentioned and polish this up I'd say its very enjoyable and would say 8-9/10. I overall recommend this campaign as the ideas, fresh takes and new units & upgrades as well as hero improvements and Arthas being badass makes up for the lack of polish and issues I stated.
And now onwards to your third campaign
