Personally I would prefer to hordes to be much, much larger.
Hundred of easy to kill zombies.
I would prefer headshot only to kill but that mechanic would probably be too irritating on horde night.
my ideal horde would be 100s of zombies that run the entire night maybe open with some special zombies like the demo guy and tail off a little at the end.
I would like there to be so many zombies they can climb on top of each other and reach a roof if left uncontrolled.
I don’t want drones but maybe as envisioned a healing drone would be okay.
I don’t like turrets but some large caliber gun emplacements would be cool.
