Insane on Nyx is Really impossible.

[Smotus]

On Year 5 (trading scenario) on Nyx moon with insane difficulty the insect attacking waves are spawning daily and even twice / day until you get busy only with repairing the defense systems.
Game over after ran out of repair materials for turrets. I was hit first by a wave of 184 flyers and 76 bugs and after a few hours another 196 flyers and 48 shirkers spawned near the base. Was impossible to face this kind of attack waves.
