The Serpent in "Quarry Quandary" and the Dragonfly in "Zelmie Sortie" both seem to have one shot kills. Why? It serves no useful purpose. The last name in "Zelmie Sortie" is OK; you can get out of the kill zone but the Dragonfly has no clear visual warning, I've seen white arc on the ground and go out of it but it is not always there (as far as I can see). This the sort of zone that leaves me thinking I should be looking for another game.
