I didn't want to throw this off topic, so I finished the thought in the General HQ Discussion board...

Anyhow, I've seen this level played on TableTop simulator and I agree that it would take forever with an obscene number of undead.
I've playtested it to try and solve the issue and found it is more suitable if the undead only spawn when heroes are in line of sight of the spawn points, so the undead don't start until the hero's turn from the first hallway, but only one undead from each X, so they'll only be getting 1 until they past that first corner.
