Fork from ToasterGod's Strong Nests, this version is highly customizeable.

IMPORTANT: default values are equal to vanilla's nests. You will not notice any changes if you do not change any settings.
(I personally enjoyed the settings in the screenshot, nests are near invulnerable until end game tech and even then require an army of spidertrons)

ALSO IMPORTANT: settings apply to worms as well as nests
