More alive than the living.

I completed the map – here are a few comments.

1. The first arena (on Necropolis territory) is inaccessible.
2. Forts need to be added to the hill, as the author intended for troops of various upgrades to join. The player should have the option to choose; otherwise, I had to decline the Dark Spirits and dismiss over 200 Rotting Zombies at the end to take 500 Plague Zombies.
3. Without forts, visiting the Necropolis outpost is pointless, as there is nowhere to upgrade the creatures.

I am attaching a replay of the final battle.
