No idea if this applies to your issue. But maybe it might help.
I recently built out an area that has about h 6-8 zombies that spawn/re-spawn in a hallway. If effect a zombie hoard!
The adventurers have to open a door, but the zombies also have the ability to open the door. creates an interesting random type experience.
Now these zombies were spawned by calling them from a script, when the PC walks though a trigger the zombies spawn, but through the magic of television ( joking) we spawn some zombies who mess up the PC(group).
so your going to need to spawn something. If interested I can share my script on spawning a monster that was inherited by the support of other more pointy headed type that haunt this forum. so it not just my script...
I have really no idea about your requirements. but , hay maybe this could be be your starting point.
