The base spawns and difficulty for the Halloween Terror Challenge Missions are identical to an Expert Junkenstein's Revenge run.
The only difference is the variant for the particular challenge which in this case is:
Zomnics explode when near a hero.
Your standard Junkenstein's Revenge strat will be sufficient for this run.

Things to note:- The time given is when the audio cue is initiated. There may be a few seconds before the enemy is fully spawned and able to be damaged.
- For the random tire spawns, listen for the call-outs by the heroes. They will say "ramparts" or "left" for a left spawn, "center" or "bridge" for a center spawn, or "right" for the right spawn.
