I'm happy to hear that it works with 2 major mods.
rofl. Good luck with explosive biters. They are worse than zerg in term of damage. They melt buffed base game defenses during my test lol. I guess K2 has better defense weapons to deal with them. If it gets too bad, you can lower their damage in explosive's biter mod setting lol.
I started to work on one race per surface feature. Hope to release it sometime next month.
K2 only generates creep on "enemy" force. There isn't much I can do on my end. I did propose a solution to K2 author. Let see if that includes in a future update. https://mods.factorio.com/mod/Krastorio2/discussion/605d800cf3bb48c41a98cd6b
re: "Can You make bobs enemies and natural evolution enemies compatible too?"
Not sure at the moment. Once this reaches 1.0, I may use the base game player assets to create a new enemy race.
