📋 About This Mod
1. 0: Created and uploaded the mod
1. 1: Fixed the various faction issues, notably with nightstalkers attacking one another. Turns out most of the robots also probably had this issue, so I readded the BigMTEnemyFaction, but only to them, so they'll attack non-robots and roboscorpions.
I made this mod because I found it annoying that all of the Big MT enemies would only attack the player and nothing else, as if we we the "outside threat". To remedy that, I've changed their faction alliances so that they were no longer on the same team, and set their aggression to Very Aggressive so they will actually attack others who aren't their allies.
- Every enemy will now attack each other. Roboscorpions might not attack other robots, but I haven't tested. Please let me know.
- I added a peaceful Lobotomite with "dialogue", since it doesn't really make sense that they would all be hostile. His dialogue changes in accordance with your perception. Travis the tragic can be found in the Cuckoo's Nest, but he may run outside once you engage with his hostile buddies.
Like I said, I didn't test everything thoroughly and whipped this up pretty quickly, so some enemies that would technically be allies might attack each other or vice versa. Please let me know if that is the case and I will quickly fix that.
INSTALL/UNINSTALL
Just extract the ESP into your data folder to install, and remove it to uninstall. It's safe to do both mid-playthrough since it's pretty much just stat edits.
