In an effort to preserve some of these maps I've made the last few years, I am uploading these sub-par maps here since my laptop recently took a crash and I nearly lost everything and have no backups.
My son and I made 2 version of this map, one Melee (posted right after we made it) and this one. This is a custom Melee version. Minimal changes were made. Where he liked using Orc Warlock as a additional unit (basically a Necromancer from Undead, just orc version).
We also have an Undead Sky Barge that instantly replaces the Goblin Zepplin if your Undead and purchase it from the Goblin lab.
