Just tried this on my server, specifically the Dead Centre campaign.
I like your method of getting past the cola part without making it completely trivial. However I do have to ask if there is any way of stopping the panic event? I've noticed that the swarms just keep coming and more often than not, it stops the bots getting to the safe room on that level.
Just a minor thing, but there you go.
Going to try it on the other campaigns later, but I knew that particular one would likely be the toughest... and it works well.
