any way to edit this or turn off? I have some long range turrets and the biters will just sit still while they dump ammo into them with 0 damage

This property is specially introduced to counteract such systems as bob-plasma. But I think it's a good idea to allow it to be disabled.
I will add the setting in the next version. The next version should be expected in the middle/end of next week

However, there will be no endless consumption of ammo. A hit causes an attack, after which the distance is reduced and "long-range immunity" doesn't work

awesome thank you! Awesome work on the mod I love it !

Rampant Fixed 1.1.0 released. Long-range immunity and oneshot protection now can be disabled in mod settings.
Thank you for your positive feedback. This gives the motivation to continue working on the mod.
