All of Core City Hostile?

[track02]

Just wondering if someone could help me out

I've done the mission to steal the shields from the protectorate and on leaving the warehouse everyone in core city seems to be hostile to me

I did kill the superintendant after bribing him in the utility building which I'm thinking may have caused it - but this was silently with a crossbow and after closing the door, no one came to investigate and I was able to leave combat instantly so I thought it'd gone unnoticed

Is there any way out of this or do I need to start the game again?

Load previous save and read about controlled areas.

I'll see if I can sneak out, otherwise I'll leave it for a while and rollback - my last manual save was a few levels ago
And the controlled zone tooltip only explains traps/explosives being traced back automatically

Hey,

Uncontrolled : You can plant traps without them getting traced back to you.
You can mug factionmembers if they are alone and no one else noticed it.

Part. Controlled :
You can mug factionmembers if they are alone and no one else noticed it.

Controlled : If you kill one, you piss off all. Traps will be traced back to you.

This is what i noticed during my UnderRail career.

Thanks, I figured this was the case too - although I don't think it's too clear from the tooltip which to me reads like it only concerns traps
I'm not able to get out of Core City at all and I couldn't find a way to edit my save so it looks like I'll have to restart

Hey,

I'd just steal the key from the superintendent and then just ignore him. He won't become hostile if you open the door.
